Can You Have Dishwasher Without Garbage Disposal? (Answered)

Dishwashers are most commonly associated with cleanliness. The dishwasher is more than just a way to get grease and soap scum off of your plates. It is important to dispose of all the small particles that are left after washing by using a disposal unit. 

Can you have a dishwasher without garbage disposal?

Dishwashers are completely self-contained appliances. They do not require additional equipment to remove dirt. In fact, dishwashers can work just fine without garbage disposal. However, in this case, you will need to use an air gap and some plumbing accessories. 

You can use the dishwasher to clean all your dishes. The food particles that are expelled are mixed with water and dumped in the sink drain. A filter system is used here. Meanwhile, garbage disposal breaks down big food particles into smaller ones. 

This allows the particles to easily be flushed through the pipes. 

However, garbage disposal is not a mandatory appliance. You don’t need a separate disposal unit because the garbage can come out of the dishwasher through the waste pipe. A lot of dishwashers have inbuilt garbage disposals. 

Some parts of the world just use water flow and heat to get the food partially out. Small to medium-sized foot particles, like fruit peels, also come out without a disposal unit.

In most European countries, dishwashers are very popular. But most people don’t have garbage disposals.  A dishwasher is all on its own. So you don’t have to install a separate garbage disposal.

Do all dishwashers have a garbage disposal? Do I need a garbage disposal with a dishwasher?

You can’t get garbage disposal in every dishwasher. This unit is not necessary to make the dishwasher work well. In European countries, dishwashers are rarely associated with built-in disposal units. They are usually equipped with filtration systems instead. 

The filtration system is a sufficiently sophisticated method. It can dispose of foot particles just like a garbage disposal. 

Garbage disposal is a big deal in America. At least one of us has a garbage disposal at home. Many dishwashers are equipped with a garbage disposal. The trend in new model dishwashers is to use filtration systems instead of disposal units, like in Europe.

You can install a dishwasher without garbage disposal. Dishwashers work fine without them. If you’re installing one, make sure an air gap system is installed. Then, when you put the plate in the washer, you have to take off the large food particles.

3 reasons why you can have a dishwasher without garbage disposal

In addition to cleaning, the dishwasher drains the dirt after each wash. The appliance does not require garbage disposal. There are several reasons for this. 

Dishwasher has an integrated dumping system:

Dishwashers come with a built-in dumping system. You don’t have to take out the dirt by hand. Most washers use a different system to get rid of dirt. In the UK, you have a filtering system on the dishwasher. It separates the water from food particles. 

And it breaks them up again by mixing them with water. That makes large foot particles smaller. You can get them out through water easier.

There is a system to remove dirt from pipes:

The main problem with dishwashers is clogged pipes. Garbage disposal prevents this from happening. Even after using the garbage disposal, however, the pipe can become blocked because of dirt accumulation. 

If there is a garbage disposal, people start throwing all the unwanted garbage in there. The result is that garbage disposal makes no difference. 

There is an air gap between the dishwasher drain and the sink drain. In case the pipe gets clogged with dirt, you can blow it out through the air gap.

Garbage disposal is noisy:

When the garbage is being disposed of, there is a great deal of noise. The noise is usually compared to the sound of a grinder. People are cutting back on it because of extra sound. 

Alternatively, if you don’t have a garbage disposal in your dishwasher, you can easily minimize noise.

How to install garbage disposal without a dishwasher?

However, you can still install garbage disposal even if you don’t have a dishwasher. Installing a disposal unit in a sink is a very common procedure.

Items you will need:

To make everything clean and dry, use a bucket and towel. In addition to your garbage disposal, you’ll need a mounting system, screwdriver, bead putty, and sink flanges.

The mounting system for garbage disposal systems usually comes in two types. One is a three-bolt system, and the other is an easy mount system. The easy-mount system is more easily installed. 

You can decide what kind of disposal works best for you based on your preferences and budget.

Install the sink flange:

To begin, add half an inch of bead putty under the sink flange. Attach the flange to the sink and tighten it. Let the flange stay in place by putting some weight on it.

Set up the mounting ring:

You need to insert the ring into the flange below the sink if you have a three-bolt mounting system. You can now secure the ring with the snap ring. You’ll need a screwdriver to attach the screws to the ring. Be careful not to over-tighten them. 

For easy mounting, screw and attach the ring to the sink flange.

Get the garbage disposal mounted:

Because you’re installing garbage disposal without a dishwasher, keep the knockout plugs in place. If you plan to install the dishwasher later, you can open the plugs and install the drain pipe. Remove the access plate to access the electrical system. 

Make sure that the cable is connected to the machine according to the manufacturer’s instructions. 

You should then place the disposal unit on the mounting ring at the top. After that, twist the locking ring with a screwdriver and tighten the disposal unit to the mount. Afterward, connect the drain line to the disposer. 

You can put bead putty on top of the pipe connection to keep it tight. Just put the bucket underneath the disposal unit. Now put the water line in. Make sure the electrical connection is safe before plugging it in. Make sure there are no leaks.

How to drain the dishwasher without a garbage disposal?

It’s a little tricky to install the dishwasher without garbage disposal. You’ll need screwdrivers of various sizes, pipe cutters, a tee, drain hose, air gap, hose clamp. 

Install the air gap in the sinkhole first. There are two sides to it. The first side goes to the dishwasher. And the second side goes down the sink. Plug one end into the dishwasher. Secure it with a hose clamp.

After you use one end to seal an air gap, use the other end to do the same. Usually, the thin edge of the air gap is attached to the washer’s drainpipe. You’ll need another pipe to connect to the drain pipe of the sink. Use a Tee to attach to it. Set up the drain spigot with the tee and pipe. 

The end of the drain spigot may have been sealed. Make sure it’s open first. It is very important to avoid the pipe from becoming clogged with a trap attached to the bottom.

Thus, you can easily drain the dishwasher with an air gap system without any garbage disposal

How do you bypass a dishwasher with a garbage disposal?

You’ll get more efficiency from both devices if you put garbage disposal in with the dishwasher. Also, you don’t have to worry about how dishwashers dispose of garbage.

It is necessary to remove the knockout plugs from the dishwasher when you add a disposal unit for the first time. You can do it by pushing the screwdriver inwards. It’ll make the knockouts go in. Remove it from the disposal.

Then mount the garbage disposal and install the sink flange. Connect the drainpipe to the drain line at the bottom. Plug the dishwasher drain pipe into the garbage disposal. You might need a hose clamp to keep it in place. Plug the disposal into a power source. 

Make sure the water is not leaking. Installation is successful. Now it’ll chop up food into small chunks and help it go down the drain.

Final Thought

A dishwasher does not necessarily need to include a garbage disposal. Each dishwasher contains a garbage disposal system, such as filtration. However, the dishwasher may still function properly without garbage disposal. Most dishwashers have an inbuilt dumping system.
