  • Washing machine drain backup

    Every so often I get water coming out of the drain when the washing machine empties (it's a newer model). I'm trying to avoid having to raise the drain and associated plumbing hence my work around of adding the additional pipe in parallel but the problem still persists. Any suggestions or blantant mistakes in my configuration?

    Thanks

        I AM A PLUMBER!!! and I don't know WTF I'm looking at there. Is that suppose to be a loop vent above the trap? Or did you add that piping to contain the backup? That has to be a lint trap I see there. Where does the other 2" PVC line go? Does that line ever back up? Did it backup befor new washer? I would have done it differently not to say what you have is wrong. Try snaking it 1st (if you can get a snake to go through all those fittings) then we can discuss changing the piping. Do you get suds coming out or just water?

          I added the piping to try and contain the backup. The other PVC line goes to a laundry sink and I only have a problem there if I'm running the sink and the washer is emptying at the same time. I will try snaking the pipe, I know it was snaked 3 years ago when we had a major backup (the upstairs kitchen sink contents were coming into the laundry tub). As far as I can tell it's just water coming out. It's a front load machine so we are using the HE detergent.

            Ah a front loader..NICE . Watch the amount of soap you use.

            3 years in between stoppages is not bad at all.

              Just for fun here's a picture of a real front loading clothes washer. I doubt anyone would really want one for home use though.

              Bill and Rick are the guys that will help you. I know nothing about anything other than trashing forums.

                Your washer has no vent. Your configuration has created an S-trap. Your stand pipe (washer discharge pipe) is too short.

                I suggest you remove everything from the wye that ties the washer to the sink on, including the 90 above the no hub coupling.

                Starting from the no hub place a TY facing to the left to pick up the washer above that another TY facing right to pick up the sink and then above that (min 4")an auto air vent (Oatley or studor) Pipe your washer stand pipe as tall as possible but do not exceed 36".

                That will solve your piping problem but you may still have a partial blockage in the under slab piping.

                  Note to potential flamers

                  I relize my suggested solution isn't ideal, but it will work a hell of a lot better than whats already there.

                    2 cents,

                    The 2" pipe that continues horizonally into the wall adjacent to the wm supply wall, what is it connected to?

                          2 cents, you don't have a vent and you have a trap that i'm not familiar with. without a vent, you will have issues of slow draining and possible siphoning of the trap seal. what is the line that you tie into the ground? looks like old cast iron? the 2 worst fixtures in a residential installation are kitchens and laundry

                          rework the vent and trap, and snake the line or jet it.

                            It's connected to a laundry sink.

                              2 cents,
                              Roots or partial clog in you main line(pipe that exits home to town sewer) could also be your problem. You say that back up "happens every so often" not every time. This leads me to believe you have a main line problem.
                              Does it seem to happen after you have used lots of water elsewhere? Like taking a shower then doing laundry soon after.
                              When roots first start to cause problems water can still get through just not as fast. I.E.You take a shower and the water is starting to back up in the main line. Once you stop using water the back up will slowly go down and you will never notice it. But if you continue to add a large volume of water(washing machine) it will backup.
                              Are the back ups happening more often?
                              Roots are a common problem this time of year in Maine and living in Portland I assume you live in an older home that has an older main line sewer.
                              TO TEST:
                              Find the pipe that exits your home. Close by you should find a clean out cap. Remove this cap(slowly, it may be holding water. If it starts to leak water then close the cap) If the line is not holding water then run your bath tub for a while. If the line is already holding water or you start getting water coming back (a small amount is normal) when you run the tub then the problem is in the main line.
