Washer Leaks Water Down The Drain

As a service company about every six months, we receive a call from a customer stating the following. I hear the water filling in my washing machine, but it never stops filling. The water just goes in the wash tub, and down the drain. What causes this? When a wash machine tries to fill up with water and the water just goes out the drain hose and down the drain, it usually means that the drain hose is either on the floor, or too far down the drain pipe.

Sometimes people try to use a washing machine in a basement, and simply lay the hose down and let the water go down the floor during. Some washing machines may operate okay with the drain hose on the floor, however most washers will simply allow the water to flow in the machine, and right out the drain hose. It’s a matter of gravity and siphoning action. Most washing machines require that the drain hose be put into a drainpipe that is at least 30 inches off the floor. That doesn’t mean shoving the drain hose all the way down the drainpipe. When this happens the water can literally get sucked out of the washing machine.

So what do you do if you have a situation where you must use a floor drain for a washer? If you must use a floor drain for a washer you can make a home made washer drain pipe that satisfies the manufacturers drain hose height requirement. Go to your local hardware store or plumbing supply house, and get some PVC pipe that is 1 and ½ inch in diameter. In addition to the pipe, you will need two 90 degree elbows, some pipe strapping and some long zip ties, plus pipe adhesive cement to connect the pipe to the elbows. In addition you will need to secure the pipe strapping to the wall. The type of screws needed will vary depending on your particular wall type. Tapcons are best for block walls.

After you have gathered all your supplies, cut a piece of pipe off that is about 35 inches long and dry fit one of the elbows to one end. Next connect the other piece of pipe to the elbow and extend it over to the floor drain. Cut the pipe so that it is half way over the drain. Next dry fit the remaining elbow on the pipe. Mark the elbow and pipe so that you can line the marks up when you apply the pipe adhesive. Do the same with the other elbow and pipe.

After your new drain pipe is assembled, use the pipe strapping to secure it to the wall. Finally put the washer back in place and use the zip ties to secure the washer drain hose to your new drain pipe.
