Washing machine draining issue: When draining, water spills over the lip of wall drain pipe and onto floor. I can drain into nearby sink just fine, so seemingly no problem with external drain pipe or machine itself. But I run a wire down wall pipe and sense no obstruction. Ever had this issue? Thoughts? Do I need to get plumbing snake to conduct more thorough test of wall pipe? TIA.

The wall pipe

Cast iron under house or pvc?

PVC

PVC

Run a snake down it there's a P-trap in the wall or there should be. If that doesn't work and you're in DFW, I have an inspection camera that would get through the P-trap only not any further.

Thanks for the offer to help. I'm on BCS. I ran a snake as far as i could get it to go. (Probably no farther than to the foundation based on the length that went in.) A little lint came back out, not much. I took a garden hose and ran water into the pipe at a pressure I think approximated washer discharge. No problems, so I'm going to hook it back up and see if positioning the discharge hose better will help.

Damn that's redneck right there. Might be ugly but gets job done! Hang it in the Louvre

Welp, failure. When I inserted the drain hose back in the wall pipe and ran a quick rinse test, same happened as before: water backed up and flowed out the wall pipe.

I am open to any suggestions before surrendering to a plumber. TIA.

Do you have a shop vac or really a air compressor


Your ptrap is clogged. Just my opinion

I may cannhelp on tuesday if you need me

Had this happen once. I was draining into the sink and then that water started backing up into a nearby shower. I ended up adding some clothes line to a plumbing snake to make it extend further and dropping it down the vent pipe from the roof. I could tell immediately I had hit the clog and released it and had no more issues.

I will try the shop vac; I don't have a compressor. I will give you a whistle Tuesday if I haven't solved the issue. Many thanks

What I don't understand about a possible clog is that I ran water using the garden hose and didn't experience a backup. Maybe I didn't run enough volume, I don't know.

Push hose past the trap

Get a Milwaukee Air Snake.

Washer drains are a thorn in everyone's side because that's where all the dirt and lint from your clothes get washed into, and it can build up in the P-trap. I would suggest using a snake, but not the hand powered one. Get one that's either machine powered or can hook onto your drill.

Hope you get it free flowing.

While you have the machine out, clean the mesh screens on the machine's hose inlets.

I like to add a silicone grommet to the discharge hose where it goes in the wall. Amazon has them for $5, something like https://a.co/d/0fqm0udj

Trap issue is very common here


My preference is to clean with a drain bladder

Or if you have a pressure washer the kits from Amazon work really well for converting it into a sewer jetter
