Thankfully, you can unclog both things without having to spend a large chunk of money.

Although this is becoming a regular practice, a home inspector will still call out the lack of a visible high loop.

It is recommended to check the manufacturing specifications of the dishwasher to see if the high loop is already built in, but most dishwasher manufacturers will still recommend the high loop be added under the sink during installation.

Air gaps are required in some states and not required in others, so check your local codes to see if you need one.

Wrong Side Of The Trap

The first problem is the dishwasher drain is connected to the sewer side of the trap. Water always sits in the bottom of the P-trap, and this prevents sewer gases from coming into the house. The dishwasher drain must be connected before the P-trap, not after it, which is what was done here. With this improper installation, sewer gases have the potential to come back into the dishwasher.

S To Connect Dishwasher Drain Hose To A Garbage Disposal

Connecting dishwasher drain hose with garbage disposal is not a herculean task that requires power or any advanced electrical or plumbing skills. It is pretty straightforward, there are just a few things that need to be kept in mind, and you are ready to go.

Step 1 Start by unplugging the garbage disposal from the electrical socket under the sink. If it is connected directly with the circuit, then turn off the disposal unit from the main panel. It is important to switch off any electrical connections because you do not want to get electrocuted.

Step 2 On the upper side of the garbage disposal is a drain tube part that will receive the hose from the dishwasher. When you try to put a screwdriver through it, you will find a metal plug blocking the nozzle.

You have to knock out the metal plug by punching it with the help of a screwdriver and hammer .

Now use the needle-nose pliers to remove the metal plug. Make sure to remove all the metal particles.

Step 3 Now, connect the dishwasher drain hose onto the garbage disposal and slide the large retaining clamp onto the end of drain hose and tighten the clamp with the help of screwdriver or wrench.

The drain hose should be looped above the connection point. The connection point itself should be at least 20 inches from the kitchen floor. If the connection point is lower than 20 inches, then an air gap must be used to prevent the drain water from siphoning back to the dishwasher.

Check The Air Gap Cylinder

How to wire disposal dishwasher Outlet. Dishwasher Outlet installation, garbage disposal.

If it is not clear, then you will need to clean it out and re-install it securely.

Thats what stops any back flow from the drain back into the dishwasher. If there wasnt a garbage disposal, an air gap assembly would need to be mounted in the kitchen sink skirt or counter.

If youre installing a new dishwasher, you dont have to have a garbage disposal. But youll need to use specific piping attachments. You must also include an air gap so that the dishwasher is in compliance with local regulations.
