Why You Don’t Have the Garbage Disposal When You Have the Septic Tank

For most people, the thing holding them from installing the garbage disposal is the fear of not meeting the city rules and a belief that garbage disposal and septic tanks are incompatible.

Contrary to those beliefs, the US regulations state that there are garbage disposals that are compatible with the septic tanks. If you will set them properly and make your septic tank receive regular maintenance you should be okay. Note, you should ensure you have the right size.

It’s not even true that your disposal will generate too much waste to clog the tank. Normally the garbage disposal units generate very little waste.

Choosing Your Garbage Disposal

  • The size of your garbage disposal

You will have the different sizes of the garbage disposal but if you have a big garbage disposal the better for you. It may look like a stereotype but when you have the big garbage disposal it will be easy to fit in your torque.

Additionally, the big garbage disposal units will have the soundproofing system to reduce the noise because they tend to make more noise. Before you go buying the garbage disposal though, check your under-sink space. Does it have enough space to fit your garbage disposal?

If you realize that you have a small space, then you should consider remodeling your kitchen especially if you are a big family.

  • How strong should it be?

This is determined by the motor. Of course, because you are using the septic tank, you need one that can grind almost everything you call waste. In addition, the best motor is the one with the ability to grind a large load of waste. Below are the list of the motor types and strength.

1/3 HP

This happens to be the weakest available yet people still love and use it often. We attribute it to the fact that they are cheaper than the other choices in the market. Also, most people in the US live alone which means that the amount of waste they produce is minimal.

They also fit in the small apartments or studios which means you still get the benefits even when you have the less powerful one

½ HP motor

These ones are also famously used in small homes but they are stronger than the one above. You can have the ½ HP motor for your regular and light Use. However, be gentle with them if you wish to use them for a longer period.

¾ HP motor

These ones are stronger than the 2 above. They can also deal with the hard food bones, fibrous fruits and veggies.

1 and 2 HP motor

They are strong and heavy enough to deal with hard food waste. You will rarely hear instances of jamming because it grinds the waste to the finest level possible. You can use the motors for your small businesses.

You should, therefore, know that it all depends on the machine’s power. Only the power will detect whether you can grind the food on the chamber. With your septic tank, you should get the advanced garbage disposals as they will give you a powerful grind.

  • What’s the estimated waste you produce?

It goes without saying that if you produce a large amount of waste you will need a powerful grind. Otherwise, you will take longer to grind the waste but also fail to produce the fine grinds. Take your time to know the waste in relation to the HP you need.

As earlier stated:

½ and 1/3 HP motors are suitable for studio or single apartments.

¾ HP if you have a family of up to 6 people this should work.

1-2 these ones are basically stronger and can handle the food waste of up to 9 people.

We have searched for the best garbage disposal to use for your septic tanks and they range between ¾ HP and 2 HP thus they are effective to use.

  • The noise

You may want to overlook the noise level of these items but the factor is very important. The noise pollution becomes a health risk if you aren’t careful. You should try and buy the quiet model if you have the money.

Insinkerator evolution is known to be the quietest option but they are usually relatively expensive. If you have limited cash, you can use some Waste King brand and still have the noise minimized. Notice that, your sink may also cause noise because of the vibration.

Therefore, having the proper sink that is compatible with the garbage disposal is the ideal solution.

  • Septic tank compatibility

Since this garbage disposal that you are interested in is meant for use with the septic tank, you want one that is compatible with the same. Not all garbage disposals work with your septic tanks. Therefore, buy those that are listed as usable with septic tanks too.

Alternatively, you may have those that are designed for use with the septic tanks only. With such garbage disposals, you have the bio-pack unit to even treat the microorganism. This makes your system more efficient for it will break down your waste faster.

  • Continuous vs Batch

Most people I know of like the continuous feed for the garbage disposal. However, the batch feed is efficient for use with your septic tank.

This is beneficial since you don’t have to release the water every time you are cleaning.

The batch feed is especially ideal if you have a smaller tank.

Major Problems Associated with Operating the Garbage Disposal with The Septic Tank

Whoever thinks that they won’t have a problem with this item is lying to themselves. It’s true that every machine is just a machine and will at one point or another fail you. Below are some of the problems you expect to have.

  • Noise

This is often taken lightly especially when it’s your first time to use the disposal garbage and you don’t know of the many other options available. Of course, over the years the expensive models have solved this problem.

You will most probably experience this problem if you have the disposals with the ½ or 1/3 HP motor systems. They make the motors weaker but don’t really take care of the noise. Of course, the last thing you want is for you to experience mental related issues because of such noises.

Therefore, buy yourself a quieter disposal.

  • Jamming

How many times have you had to call your plumber to take care of your drainage system?

It’s true to say that at one point or another, this item will jam even if you have the high-end ones so it’s best to be psychologically prepared. I’ve seen the ones that are designed to cater for this problem but they still jam. The only thing it does is reduce the number of times it jams.

Worry not though because fixing the jams is a non-issue for the garbage disposal.

  • Clogging

You have the garbage disposal being part of the kitchen drainage system which means that the clogs are unpreventable. Unfortunately, clogging is a little more complicated than the jamming. You will find the clogging in the drainage pipes.

With the basic knowledge in plumbing, you could deal with the issue but you should always try to consult your plumber.

Important Points to Have in Mind When You Have the Garbage Disposal for The Septic Tank

  • Notice that this is not your trash can

The garbage disposal works like your regular trash can but it isn’t. Don’t start putting stuffing your veggie peels into the cans as this may lead to its quick distraction. You don’t also want to have clogs in the septic tanks thus causing a health hazard.

Unless your garbage disposal can finely break down the waste into even finer particles, it will have a massive impact on the septic tank to put large waste items.

  • Don’t overuse the garbage disposal

If you have the garbage disposal right now, you should consider using it sparingly because if you use it every other time chances are that it will spoil your septic tank. For the septic tank, in fact, make sure the large waste pieces are thrown into the trash can.

You can even use the compost roller to make compost leftover food waste.

  • How frequently should you pump the septic tank?

This is an important factor of consideration when you have a garbage disposal because you want to avoid the maintenance cost as much as possible. But, for you to know this, you need to know the size and capacity of the septic tank you have.

What’s your daily waste amount both in liquid and solid form? Remember, houses with more people will fill up faster than those with fewer people.

However, note that you should always check or pump the septic tank every after 2 or 3 years. This keeps you safe from clogging and jamming.

  • How long does your garbage disposal last?

The regular garbage disposal will last anything between 8-15 years subject to the care and maintenance. What will cause you to need a quick replacement is the dull blades, burned out motor and rust.

  • It shouldn’t leak

When you have just installed your garbage disposal, you don’t expect it to begin leaking. If it’s leaking then know that it’s not tightly fitted. However, if you have the old garbage disposal then chances are that it’s old and rusted out.

How to Tell When Your Garbage Disposal Is Bad

We all know how essential this item is in your kitchen especially if you have those weekend nights with friends at home. They help to ease the cleaning process so when they are bad, cleaning becomes a nightmare. But, how do you know when your garbage disposal is bad?

  • It doesn’t turn on or start

This is the simplest of all to know that it’s bad. You have tried to turn it on several times but it just won’t start. In this case, know that you have a faulty garbage disposal. But first, confirm that this is not just your circuit breaker problem.

  • You often reset

    your garbage disposal every so often

The machines are sometimes faulty and you can just reset them before they begin working normally again. However, when you must frequently reset the buttons then it’s time to know that you are using a faulty item.

  • It will take longer to break the waste down

A good garbage disposal will break the food waste fast. As they continue to age, like anything else, the garbage disposal has difficulty in breaking the food down.

  • If it makes

    the screeching noise

These gadgets are never quiet but they shouldn’t make the screeching noises. You could have the garbage disposal making the screeching noise when the grates have shifted or the motor is worn out. Take care of these problems and you have a noise free item.
