In the first section of this article the basic first steps on how to install a washing machine drain pipe were explained. At this point you should have the y-fitting installed in your drain line, ready to hold the standpipe and finally the actual installing of the washing machine drain pipe. Here are the last few steps to follow in order to complete the job.
Step 1 - Installing the 90 Degree Elbow
Clean the remaining opening of the y-fitting with a clean rag and then apply the PVC glue on the inside of the opening. Apply also the glue on the outside of the elbow and then insert it in the y-fitting. Position the elbow with remaining opening facing downwards facing the floor. Then hold it for a couple of minutes until the glue dry completely.
Step 2 – The PVC Drain Pipe
Now it is time to install the long PVC drain pipe. This should be attached to the remaining opening of the elbow standing vertically by the wall. Hence, as with the y-fitting and the elbow, cover the edge of the pipe and the opening of the elbow with the PVC glue and join together. At this point, the pipe should be vertically standing at 90 degrees with the horizontal drain line.
Step 3 – Trim the Pipe
If the pipe is too long, cut it to the required height using the reciprocating saw. The top of the pipe should be higher then the washing machine’s water level so roughly it should be about 34 to 36 inches atop the floor. Thus, if the pipe is too short, it will not function properly and the water will not drain down the pipe.
Step 4 – Strap on the Pipe
Use the pipe straps with the screws to attach the pipe to the wall by inserting the pipe in the straps and fasten them into the wall using a hammer. Be careful not to hammer them too tight to the wall otherwise you can damage the pipe. Use about 5 pipe straps and leave them distant about 5 inches from one another.
Step 5 – Connect to the Washing Machine
Now that the pipe is ready, you can connect it to the washing machine’s hose pipe. If the pipe is inside the machine, remove the control panel by unplugging its connectors and slide the cabinet towards you and remove it. Then, release the clamp that secures the hose to the pump and attach the pipe. Then fasten it again with the pump using the clamp.
At this point your washing machine drain pipe installation should be ready and complete. You should have a drain pipe vertically connected to the main drain line at a 90 degree angle using an elbow. The top of the pipe should also be attached to the washing machine’s drain hose. However, run some water to check that everything is working correctly without any water dropping.
