Wondering if garbage disposals and septic systems work well together? It might seem tricky, but it’s not! There are many disposals that are safe for septic systems—you just need to find the right ones. To make it easier, check out my review of the Best Garbage Disposals for Septic Systems and skip the hassle of searching everywhere!

Review of the Best Garbage Disposals for Septic Systems 

Here you will read our review on the top garbage disposals for Septic systems. Our team has tested these disposals under different circumstances and pressure and found them best in the business, so here is our take on them:

Moen GXS75C GX Series

Unboxing 

Moen Host series garbage disposals hold a special charisma. Everyone wants to have it to experience its exceptional features. I also tried the brand by ordering the GXS75C model. The parcel came and included a garbage disposal with a power cord, spare parts, and an installation guide. 

Review

As soon as I took the garbage disposal out of the well-arranged box, the first of the appliance appearance made my day. From a lightweight body, and tough build to the pre-installed power cord, it conveyed great performance in the future. 

After analyzing the GXS75C garbage disposal model for several months, I found out that it consists of many impressive features. Firstly, the featherlight framework of the disposer confirms that you can position it in its desired place without asking for any help. Still, you must consult an expert as the garbage disposal goes into the septic system for further food reduction. 

In addition, the garbage disposal is equipped with the second most powerful horsepower, which is 3/4 hp. It means you have a good opportunity to add a variety of food items down the drains without any worry of clogging. Now chicken bones, celery, fruit pits, and vegetable scraps are seen to be on the kitchen countertops as efficient garbage disposal swallows them in one go utilizing 2700 RPM. 

What impresses me the most is the sound-deadening feature of a Moen garbage disposal. No matter whether you run it in the presence of guests or for routine food disposal, there is no chance of hearing disposer-generated loud vibrations and noise that may eventually distract you for further cleanup. The credit goes to SoundShield technology.

However, the primary concern is finding the compatibility of the Moen GXS75C garbage disposal with domestic septic systems. Know that the appliance matches the working mechanics of the various standard-sized septic tanks without harming the bacteria working inside for solid waste decomposition. 

Testing the garbage disposal reveals to me that it is unbeatable in its performance compared to the other models of the same category. However, it does not give enough margin to clean the disposal thoroughly. Because the garbage disposal comes with a non-removable splash guard, maintaining it via different cleaning tactics is a bit difficult. You may try Frigidaire 3/4 HP Corded Garbage Disposal which offers a silver guard for stopping metal items from sliding inside. 

Key Specifications and Features

• Feed Type: Continuous feed
• Horsepower: ¾ HP vortex motor
• Grinding Chamber: stainless steel construction
• Speed: 2700 RPM
• Capacity: 3.2 liters
• Septic Safety: yes
• Sound Reduction: Sound Sheild technology
• Mounting System: EZ mount for convenient installation
• Power Cord: Included
• Warranty: 10 years

Pros

• I like how compact dimensions make the garbage disposal fit under the kitchen sink cabinet. 
• The garbage disposal’s permanent magnet vortex motor grinds the food waste rapidly.
• My sink area remains stink-free due to the disposal unit’s 360-degree rinsing feature for food scraps.
• Sound insulation is far better than regularly available garbage disposals. 
• Available power cord saves much time in installing it. 

Cons

• The Moen garbage disposal should provide a removable drain stopper.

Why Should You Buy It? 

Moen’s under-observation garbage disposal is one of its types. It lets you use the disposal on alternate days, clean leftovers from the plate, and whatnot. Well, there are many reasons why you must buy garbage disposal, that is sound insulation, a 10-year warranty, adequate grinding power, and septic system safety. 

Why Should You Don’t Buy it?

Moen garbage disposal is designed with a non-removable drain stopper, and that makes it a big no for purchase. 

Final Verdict

Moen GXS75C is worth your investment. Because it contains durable quality grinding components, an energetic motor for food reduction, and professional design. 

InSinkErator Evolution Septic Assist

Unboxing 

Reviewing the best garbage disposal for septic systems without mentioning InSinkErator Evolution Septic Assist, is not possible. Since the particular garbage disposal is designed for this purpose, I made up my mind to analyze the functions personally. The parcel came and brought a 3/4 hp disposal unit with a bio-injection cartridge, essential hardware components, and a user guide. 

Review

Taking it out of the box, the garbage disposal was giant compared to standard-sized ones. Also, the dimensions of the height and width were of larger values encapsulating the bio-charge automatic injection in a cartridge on the lower body.

How far the garbage disposal could maintain the working of the septic tank without much interference was not without installing it. I genuinely called a technician to get the disposal unit fixed for me, so that it would not show errors while operating. Also, the InSinkErator’s exclusive mounting assembly was a helping hand in obtaining the final finish of snug fitting. 

Describing the specifications that make up the grinding power reveals that garbage disposal utilizes a 3/4 hp Dura-drive Induction motor and causes the impellers to rotate at 1725 RPM in sending the grated food chunks from the 40-ounce grinding chamber to the septic tanks. Here microorganisms are active to accept the treated waste and segregate the solid organic waste for further decomposition. 

You must know that the bio-charge automatic injection that contains enzymes is released in the septic tank every time a garbage disposal processes food, establishing the harmony between the two. However, you must refill the cartridge to extract good results. Personally, I make it fill every four months and you must decide according to your requirements. 

InSinkErator Evolution Septic Assist garbage disposal performs a dual duty, well-being of the appliance and septic tank, it is crafted out of durable stainless-steel material. No matter how much cold water you flush down the drains, the layer of chromium oxide protects the disposal unit from corrosion build up and the same goes for the linked septic system. 

The only disadvantage of the garbage disposal you and I observe is the costly maintenance. Since it is directly linked to the septic tank, any malfunctioning components harm the working of bacteria. Even then, this garbage disposal is unbeatable when compared to its competitors like Kraus KWD100, Moen GXP50C Prep Series PRO 1/2 HP, and the like. 

Key Specifications and Features

• Feed Type: Continuous Feed
• Horsepower: ¾ hp
• Motor: Dura-drive Induction Motor
• Speed: 1725 RPM
• Grinding Technology: 2-stage multi grinding
• Sound Insulation: Sound Seal
• Warranty: 8 years
• Grinding Components: stainless steel
• Grind Chamber Capacity: 40 ounces
• Weight: 19.11 pounds

Pros

• Evolution Septic Assist fights well against usual wear and tear due to its durable stainless-steel material. 
• The eco-friendly bio-charge feature proves convenient for food grinding and ensures the septic system’s good health.
• The 40-ounce grinding chamber handles a lot of food waste in one go. 
• I found the garbage disposal among the quietest with Sound Seal technology, reducing noise and vibrations up to many decibels. 
• The anti-jam and anti-reverse features improve the garbage disposal’s functioning. 

Cons

• The garbage disposal does not come with a pre-installed power cord, you must buy it from hardware stores.
• Evolution Septic Assist comes with the challenge of installing it with extra values of dimensions.
• Keeping the bio-cartridge injection in its place becomes tricky.

Why Should You Buy It?

There are many reasons why you should go for Evolution Septic Assist. Among them are:

1. Solid waste is decomposed in the best possible way and reduced in the amount for going into landfills. 
2. Garbage disposal shows exceptional performance using ¾ hp, 1725 RPM, and sharpened stainless steel swivel lugs. 
3. It includes eco-friendly technology of bio-charge injection and grinds food waste in the disposal and septic tank without forming clogs. 

Why Should You Don’t Buy It?

InSinkErator Evolution Septic Assist demands attention to operate it so that the liquid containing the microorganisms is released in the septic tank as required. Also, the installation is problematic for DIYers. 

Final Verdict

No matter how many garbage disposals you think to buy to link with the septic tanks, Evolution Septic Assist from InSinkErator is different. Plus, it is cost-effective and you have the option of giving it a trial before the actual purchase. 

InSinkErator Badger 5 1/2-HP Continuous Feed Garbage Disposal

Unboxing

The next disposal unit on the list was Badger 5, the lookalike of Badger1. I readily confirmed the order to know how it would earn the reputation of a good performer compared to its competitor and with my cooking schedule. Upon unboxing the parcel, I got the 1/2hp garbage disposal, spare parts for installation, and an instruction manual.  

Review

At first glance, the disposal unit looked like an exact copy of the Badger 1. From the same old conventional design, continuous feed to the galvanized grinding chamber, I found no prominent differences in appearance. However, the weight of the under-consideration garbage disposal was almost close to its competitor Badger series model. 

After stopping myself from comparing both appliances, my curiosity about utilizing the Badger 5 provoked me to install it without any further delay. I appreciated the disposal unit offering the adequate 12.7 inches height and 6.3 inches width, for it made it much more convenient to hold and handle the disposer while lifting it up to the sink flange for a snug fit. 

Furthermore, I observed that the appliance is manufactured using galvanized steel material confirming the long-run durability. The efficient grinding components do not leave any food particles in the grinding chamber when you fill it up to 26 ounces. Hence, lesser chances of clogs. Also, the corrosion buildup has subsided from garbage disposal for longer years. 

Another interesting fact about the Badger 5 is that you can make it swallow some tough food items without harming the garbage disposal. Being 1/2 HP model, it can make up for the grinding of potato peels, chicken bones, green salad, fruit scraps, and whatnot. On the other hand, you must take precautions while adding citrus down the drain. 

Even then, there is a lot to say about the Badger 5, the garbage disposal does not incorporate the additional features you desire as compared to the premium InSinkErator disposers. Among them are, anti-reverse, multiple grinding stages, noise insulation, availability of the power cord, and the like. 

But you must rely on what the garbage disposal provides for kitchen waste management and if not satisfied get your hands on other InSinkErator models.

 Key Specifications and Features

• Feed Type: Continuous feed
• Horsepower: ½ HP 
• Grinding Components: Galvanized steel
• Speed: 1725 RPM
• Grinding Chamber Capacity: 26 oz
• Warranty: 3 years
• Septic Safety: yes
• Mounting Assembly: Lift and Latch Technology
• Motor: single phase, Dura-drive induction motor

Pros

• The Badger 5 can easily fit inside my tight-fitted kitchen cabinet, having no issues with placement. 
• Badger 5 is budget-friendly and does not break the band while buying it. 
• I found out that the continuous feed design of the disposal unit cut a significant amount of time in food processing. 

Cons

• The noise reduction of Badger 5 needs much improvement, with the incorporation of InSinkErator sound deadening technology. 
• The garbage disposal has only one stage of grinding.

Why Should You Buy It?

InSinkErator Badger 5 is a must-try garbage disposal unit. It fulfills all the requirements in an affordable price range. The appliance is designed to meet the average food waste protocols for a small family of two people combined with a 1/2 hp dura-drive motor and a reset button to keep situations under control. Plus, it is septic system compatible. It means you can easily get it attached and obtain a hundred percent result of food disposal. 

Why Should You Don’t Buy it?

Badger 5 comprises only the necessary specifications and does not have extra features to drool over.

Final Verdict

Insinkerator Badger 5 reaches you without making a dent in your pockets. It makes you use it and helps you decide your preferences for choosing over-priced luxurious appliances in the future. 

Waste King L-111 Garbage Disposal

Unboxing

Discovering the best stainless steel garbage disposal for kitchen waste management took me many days of hunting. Finally, my search stopped on the Waste King L-111 garbage disposal. Receiving and unboxing the order revealed a ⅓ hp garbage disposal, mounting assembly, hardware components, a splash guard, and a user guide. 

Review

The grey-colored appliance had the same slim-fit body from the top to the bottom. It came equipped with a reset button and an attached power cord protruding from the opposite direction of the overload protector. Another thing that caught my attention was the cylindrical shape of the disposal unit making it recognizable from the crowd of many. 

Testing the Waste King L-111 means walking on the path of effortless installation. The standard-sized garbage disposal of 12.75 inches in height did not bother me when I placed it under the kitchen cabinet by using the timesaving EZ mounts. Overall, it took me 20 minutes to do the process of lifting the disposal unit and locking it into the flange. 

Moreover, what impresses me till now is the coupling of the 1900 RPM speed that the magnetic motor uses and easily manages ordinary or somewhat tougher food waste, such as green vegetables, waste peels, fruit scraps, or fish bones. 

However, the construction of the disposer is something that I like to mention, that is a galvanized steel body, stainless steel grinding components, and polymer glass-filled grinding chamber. Also, the professionally manufactured garbage disposal lets the rust formation on the impellers, swivel lugs, and shredder rings on the side even in the presence of cold water for grinding. 

The septic safety goes hand in hand with the Waste King L-111. You feed your garbage disposal with organic waste that eventually reaches the septic system so that the microorganisms further reduce them and save the environment loaded with heavily occupied landfills. 

The Waste King L-111 is regarded as probably the most featured and recommended garbage disposal under $100. At the same time, you cannot deny that it comes with a removable splash guard for easy deep cleaning. However, you must try Waste Maid 10-US-WM-058-3B because it comes with anti-jamming and costs less than the product under observation. 

Key Specifications and Features

• Feed Type: continuous feed
• Horsepower: ⅓ HP
• Weight: 7.5 pounds
• Speed: 1900 RPM
• Construction Material: galvanized steel
• Motor: permanent magnet motor
• Septic Safety: yes
• Mounting System: EZ mount for easy installation
• Warranty: 2 years
• Power Cord: 32 inches pre-installed power cord

Pros

• The garbage disposal ensures durability with stainless grinding components.
• The Waste King model handles food waste effectively.
• The installation is a breeze with an available 32-inch power cord, 
• I found the Waste King L-111 a good value-for-money product.

Cons

• The build quality could be better instead of galvanized steel.
• Foul odors and frequent clogging are major issues related to L-111.

Why Should You Buy It?

You should buy the Waste King L-111 for three main reasons:

1. It comes in everyone’s budget.
2. The moderate-sized garbage disposal works well in coordination with a septic system.
3. The garbage disposal comes with a pre-installed power cord to save the time you look for a separate one. 

Why Should You Don’t Buy it?

You must not buy Waste King L-111 due to the no apparent sound insulation. Also, the low horsepower motor restricts your activity of disposing of food waste to a great extent, that is only once in a while. 

Final Verdict

Waste King L-111 is a must-buy in a lifetime, for it functions more professionally than its competitors of the same category, specifically L-1001. Also, the price range is not a hurdle, I advise you to stick to the one with promising results. 

HISSUN Garbage Disposal 3/4HP, 4000RPM

Unboxing 

The thought of experiencing the garbage disposal working other than InSinkErator was turned into reality when I found Hissun 3/4 hp. I ordered the disposer without any delay and reviewed the product to include it in a list of the best garbage disposals for septic systems. 

The parcel when unboxed, revealed a 3/4hp Hissun garbage disposal with a power cord, multifunctional stopper, mounting assembly, drain elbow, dishwasher connector, and instruction manual. 

Review

The compact design in the hues of matte black appeared different from the other garbage disposal models. It was a full-package disposer offering the power cord, an ergonomic design stopper, a thick splash guard, and a reset button. What else I could expect at first sight? 

Since the garbage disposal was a continuous feed type and had a power cord, I looked nowhere other than focusing on the installation. The space-friendly garbage disposal having 13.86 height adjusted well under the kitchen cabinet without assistance. Also, the 3-bolt design made the installation much easier, unlike Evolution Septic Assist which is big and requires shifting the surrounding things from the area. 

Furthermore, what you get is a ¾ hp motor and 4000 RPM spinning speed of the impeller that is professional enough to grind waste and convert it into powder. Plus, the 7-stages food grinding is incredible. You will be surprised when you learn that it can handle nuts, fruits, vegetables, and chicken/beef bones, the waste of five-to-right people. 

Being a 3/4 hp garbage disposal, it provides you with a stainless-steel grinding system. It means having the guarantee of utilizing the corrosion-free and crack-free disposal for years to come. There is also a stopper and a thick splash guard that prevents backup of food content and water. 

Plus, the brand claims that the HISSUN best 3/4 hp garbage disposal has a design with a sealed shock-proof body and various noise insulation materials that reduce self-generated noise by up to 30%. But what I observe is that it proves a total failure in reaching this percentage. You hear a considerable amount of emitting noise with no chance of reduction. What I want to say is that you have the option to replace it with an alternative, that is InSinkErator Badger 5XP Garbage Disposal.

Key Specifications and Features

• Feed Type: Continuous Feed
• Horsepower: ¾ HP 
• Speed: 4000 RPM
• Grind Capacity: 1.2L 
• Grind Stages: 7-stage grind
• Grinding Components Material: stainless steel
• Weight: 13.52 pounds
• Mounting Assembly: 3-bolt design
• Power Cord: included
• Sound Reduction: sealed shock-proof design, reducing noise up to 30%
• Warranty: 24 months

Pros

• The 7-stage food grinding is something I experienced for the first time and like it.
• The available power cord makes the garbage disposal installation process a breeze. 
• I can put a variety of food items in the grinding chamber, for it chews everything in a go.
• I like the compact design of the disposer, letting other things be seated at their position. 

Cons

• The constant leaking problem makes me replace the disposal unit.
• Sound insulation needs immediate improvement. 

Why Should You Buy It?

You cannot resist buying a HISSUN ¾ hp garbage disposal after glancing at the specs, such as continuous feed design, a power cord, 7-stage food grinding, a high-speed motor, and a 3-bolt mounting assembly.

Why Should You Don’t Buy it?

The only reason you should not get the Hissun disposal unit is its incapability of reducing sound. Moreover, it can only be sufficient to handle food waste disposal when run on alternate days.

Final Verdict

HISSUN ¾ hp garbage disposal serves its best with all the specifications and features. It sorts your kitchen’s food disposal at a much faster pace and is a gadget worth trying. 

Chooba Garbage Disposal 3/4HP, Continuous Feed

Unboxing 

I didn’t know that there were many garbage disposal models that compete well when the discussion was about including them in the list of septic-safe machines. One such I encountered was Chooba 3/4 hp garbage disposal. The parcel arrived and was unboxed, I got the disposal unit with a power cord and spare parts for connecting the dishwasher and for installation. Also, the package included a hex wrench or instruction manual. 

Review

At the initial sight, I got to know that Chooba garbage disposal was not something that you call ordinary. Instead, the first appearance presented an industrial design with designated inlets or outlets. Also, the stainless steel material, a reset button with a power cord spoke about the great performance in the future. 

I turned my focus toward installing Chooba ¾ hp garbage disposal. The compact dimensions, such as 13.8 inches height and 7 inches width positioned the same way I wanted for my under kitchen cabinet. Also, I had the plan to connect the dishwasher to the garbage disposal, the dishwasher connector made everything easier and time-saving. 

When analyzing the disposal unit from the lens of performance, the ¾ hp appliance leaves no stone unturned every time I run the machine. The mystery behind smooth food grinding is nothing but a fast-paced DC vortex motor that does not spare any food particle and puts effort into reducing it into atom size. No matter whether you stuff inside fish bones, fruit scraps, and vegetable peels, every slice is reduced to its last. 

Another plus point is that now you can stuff food items in large amounts because the Chooba garbage disposal offers 4-stage grinding components. The professional stainless steel grinding components within the disposal chamber work in unison and let you achieve higher results of food grinding in the septic tank for further processing. 

Moreover, the negative side is yet mentioned. The sound insulation is only minimal, and the claim that garbage disposal reduces 50% of the emitting noise is superficial. The reality is that it makes a weird noise that you end up thinking of buying a new one. Otherwise, you can try Frigidaire 1.25 HP Corded Garbage Disposal FF13DISPC1 for years to come. 

Key Specifications and Features

• Feed Type: Continuous Feed
• Horsepower: ¾ hp
• Motor: DC Vortex Multidimension Motor 
• Food Grinding Stage: 4-stage
• Speed: 3800 RPM
• Sound Insulation: incorporate SoundShielding material, 20% quieter
• Weight: 11.8 lb
• Grinding Components: stainless steel
• Power Cord: included

Pros

• The performance of the disposal unit is impressive for five to eight members.
• The 4-stage grinding chamber is mind-blowing in handling food waste all at once.
• The design of the Chooba ¾ hp adjusted nicely under the sink cabinet without causing much trouble for other things.  
• The durability of the garbage disposal makes it competitive compared to other appliances.

Cons

• Chooba garbage disposal needs to improve the sound-reducing feature. 

Why Should You Buy It?

The disposal unit is designed with ¾ horsepower, stainless steel construction, and with high RPM motor that reduces food particles into pulp fulfilling the requirements of kitchen cleanup on alternate days. 

Why Should You Don’t Buy it?

Many downsides of the Chooba garbage disposal restrict you from buying it. The disposal unit is not actively involved in reducing self-generated noise. You must want a better disposer with extraordinary noise deadening. What are your thoughts?

Final Verdict

The Chooba disposal unit has tried introducing features to become the solution to food waste management. Plus, the strength of the appliance lies in the fact that it comes with a power cord to make it function. Hence, you must grab it and utilize it to get a cleaner kitchen than ever. 

Do You Need a Special Garbage Disposal for Septic Systems?

Not really, the special one may provide better security for your septic system ensuring the longevity of the bacteria but the standard ones from renowned brands, such as InSinkErator, Waste King, or Moen garbage disposal do the same. 

As the garbage disposal works to pulverize food items into pulp so does the septic tank. The only difference is that the septic system segregates solid waste from water and lets the bacteria reduce it. Also, there are some sets of rules highlighting what to put inside and whatnot to let the garbage disposal and septic system work in harmony. 

What Not to Put in Garbage Disposal with Septic Tank?

The unity of the garbage disposal with septic tank is only possible when you have the know-how of what to put inside and whatnot. As the garbage disposal accepts organic and biodegradable waste, apply the rule to the septic tank too, and see how food-reducing machinery and waste handling system go hand in hand. The list is mentioned for you to note down. 

• Oil, grease, and fats
• Kitchen cutlery
• Fibrous food items
• Eggshells
• Coffee grounds
• Jewelry pieces
• Onion Layers 
• Banana and Potato peels
• Seafood Shells
• Nuts
• Chicken/Fish Bones
• Non-food items, such as paper towels, tissue paper, or cigarette butts.

Summing Up

On the road to searching for which garbage disposal suits your requirements when discussing the septic system, I have mentioned some of the septic-friendly disposers to choose from while keeping in mind the price range, specifications, and features. The abovementioned appliances are carefully analyzed from every aspect to recommend the close-to-ideal food-reducing system.
