Washing machine drain pressure...
Posted by Kevin on January 04, 1999 at 02:47:56:
I have a washing machine that drains so fast that the water cannot go down the drain fast enough and it backs up into the house.
I have talked with several plumbers, and they have suggested (the costly) way to fix it is to tear out the wall and replace the
pipe with a larger one that will accomodate that amount of drain flow. Some of the plumbers have suggested trying to reduce the
amount of drain flow by restricting it somehow but I am not sure the best way to try to do that. If you have any tips, please
email me. Thanks.
