Once a week I am visiting customers due to their washing machine backing up and flooding part of the house. Your washing machine drain overflowing can be influenced by any of the following:

· Clogged Drains – Most washing machines are located near the kitchen and over time grease build-up collects on the inside of your sewer pipe reducing the overall pipe size
· Venting – The venting requirements have increased over the years to allow for the increase speed and volume flow rate put out by newer washing machines.
· Soap Suds – Using too much soap may cause suds/bubbles.
· Belly – Sewer lines may have a belly. By code drains are to slope 1/8” fall per foot.
· Roots – tree roots are notorious for penetrating sewer lines.
· Cave-ins – shifts in the ground can put stress on drains eventually cracking the pipe.


Mock Plumbing Repairs LLC will be happy to help you diagnose what exactly is causing your washing machine to overflow.

Well sure it is...But only if its sized right..Right? I always lay out my 1-1/2" Laundry drains in with no vent and 1/8" grade. Sometimes if the flow rate isn't good, I'll extend the standpipe. Wait, oh yeah, that was pre-code years.:laughing:

Also, it's not always 1/8" per ft.

Those pesky bendy things always slow things up, too. Just pipe it right into the stack! Flows better that way.
