I am remodeling my basement bathroom. Shower & toilet removed, capped both. When I try to use my washer, also in basement, water comes out of the line where the hose is. Didn't have any water problem until we removed the toilet & shower. Why is water escaping wherever it can?

Did you cap any vent lines?

Did you cap any vent lines?

No. The only vent line I am aware of is on the roof. We checked that for clogs but fpund none. We capped where the toilet, shower & sink was. We have not sealed the caps, they are sitting over the openings except where the toilet was is a towel stuffed in.

Possible something got in the drain line when removing the fixtures and has now moved further into the drain line causing issue.

Otherwise, a coincidence here and the washer drain line is simply clogged and needs to be snaked/cleared... ;)

Also, as part of the remodel I hope you are planning on adding vents to the plumbing in the basement, right?

OK! You removed the plastic test caps from your drainage. Why would you do that leaving a direct open line between between your house and the city sewer allowing sewer gas to enter your house? Not too swift a move.
Mark pretty much covered it. You might have lost a piece of plastic down the drain where it's now blocking your washer drain or .as Mark pointed out, it could simply be a coincidence. At any rate snake the washer drain line. Good luck, Tom

Ok. I Don't live in the city. We didn't remove anything but the shower, sink & toilet. So we cap those places. Now, when we put a cap over where the washer pipe is, just to see, it blows one of the other caps off & floods the basement. So whatever we cap off it finds another way to overflow. I have no plumbing issues upstairs in the main part of my home, no backups or overflows.

Hi Kathyrn

Like we said, you have a blockage in the drain pipe. You need to get someone in with a snake and clear the drain line.

Thank you all. I was just under the impression that maybe there was no clog since I don't have any backup/overflow problems in the main part of the house & the problem didn't happen until we removed the stuff.

Problem appears to be isolated to the branch drain serving the downstairs bath and washing machine drain.

Good luck!

If these are test or hard cape s we're talking about then they must be glued in place not simply jammed in place. Good luck Tom
