It would happen every so often but no its every time we try to do laundry.

The pipe is clear/no blockage.. When the water drains it seems like air is pushing it back out the top of the drain instead of letting the water go down into the well.


Any ideas for fixing this problem?

Thank You Steph ~

Hi Steph,

If your draiun lines clear and as you say," The pipe is clear/no blockage.. When the water drains it seems like air is pushing it back out the top of the drain instead of letting the water go down into the well."
This sounds like it may be a blocked vent. A back surge that pushes air ahead of it should go up the vent and not the stand pipe. What size is your trap and stand pipe?

You say," The pipe is clear/no blockage.. " but something's changed to give you this problem that you have. New washer? Are you QUITE SURE the drain's clear?
Perhaps you should look a little closer at a washer surge pipe, (see image).
This goes along with what I've been advising all along. Sealing off the washer hose with a compression fitting,(see image) and forcing the pump to push the water out into the main. If both the drain and the vent's clear,( How do you know for sure?)then you have two options open. You may seal off the washer hose making it a closed circuit or you can build a washer surge pipe. Let me say right now that if the drain pipe's blocked the only thing that will solve the problem is to snake and clear the drain line. Let me know what you decide. Good luck, Tom

If I missed this the first time around then shame on me! Have you checked the dry well to be sure it's not full? If not then get out a shovel and check it out. Good luck, Tom
