How to Install a Washing Machine Drain Pan

Installing a washing machine drain pan can help protect your floor from water damage caused by washing machine leaks.
These pans catch water leaking from a machine and funnel it out through a connected hose into a nearby floor drain. Since these pans are set underneath the washer, you'll want to have an assistant help you lift up the appliance and set it up in the pan. Drain pans are inexpensive, simple to set up and may save you hundreds of dollars by preventing an accident.

Step 1

Set the drain pan on the floor where the washing machine will be installed. Knock out the plug on the side of the drain pan. Insert the hose attachment through the side and secure with the retaining screw. Slide a hose over the drain nipple and secure with a clamp. Run the other end of the hose into a floor drain.

Step 2

Have an assistant help you lift the washing machine up and gently set it into the drain pan. Take care not to crack the plastic as you do so.

Step 3

Wrap both the washing machine inlets and water supply outlets with PTFE plumber's tape. Trim off any excess. Connect a washer hose to the hot water inlet on the washing machine. Connect the other end to the hot water supply. You can identify the hot water supply either by the color coding (red) or by feeling the pipe. Connect the cold water inlet to the cold water supply with the other hose. Tighten the couplings on the end with the pliers.

Step 4

Connect the washing machine drain hose. Insert the gooseneck end of the washing machine hose into the vertical drain pipe. Secure with a plastic cable tie or piece of wire.

Step 5

Level the machine. Place the spirit level on the front of the washer, facing you. Adjust the washer legs with the wrench, one at a time, until the machine is level.

Step 6

Plug the washing machine into an available outlet.

Step 7

Run a small test load of laundry on the machine. Adjust the legs if needed to keep the washer level. Tighten any hose couplings if needed.
