1. ...push it on 3/4 to an inch onto pipe...

2. insert drainpipe into coupler, tighten, and drain is complete.

3. Supply system/Drain system.

4. In order to attach 1-1/2 inch dump valve to plastic drain pipe...we must do a conversion; we found a 1-1/2 PVC compression fitting that will slide right over 1-1/2PVC coupler...

5. Now we are ready to attach dump valve...It took 3-4 trips to H'ware, then feed store, where I found the 'schtuff', for this conversion.
