    How do I install a vent on basement slop sink?
    I have to replace a very old slop sink in basement. It has 1 1/2" Galv pipe for drain, but it isn't vented. I am changing because my washer drains to it and has over flowed a few times,but always flows poorly. There is no clop in line,as I have snaked,but didn't help. I will be using solid PVC. If I tie drain to tee,and extend pipe 3 feet high,WILL THIS WORK? Thanks John :confused:

    John , they make a under counter vent that you can try . If that don't work CUT the drain line and put ay then a 45 then a pice about 6 or 7 ft high use 1and 1/2 or 2 in pvc pipe. You can any of these parts at a plumbing store or Lowe's, home depot. Hope I could help

    FLYING EAGLE ----------- I never heard of the under counter vent?? Where would I look for this at? Do either of these vents need to go to the outside? I do not want to do that. Thanks a lot John Da :)

    They are called a studor vent or air admittance valve. Don't need to go outside.

    THANKS STEW!! MY HOME DEPOT IN NJ probably won't have it, not much in plumbing dept. I will try Lowe's, if some one knows what it is. Does it come in 1 1/2"?

    I don't recommend ferco-ing over top of old stuff. You really need to use the fittings and adapters as they were intended, they might work... but only for a while.

    Is the nipple stuck? You might be able to judiciously use a dremel tool or a chisel to split the old nipple. I've spent hours and hours getting old pipes apart - the fix only takes about 5 minutes afterward. Seems anti-climactic, but the results are always long-lasting.

    If you have a digital camera, maybe a picture will help get some suggestions for the fix. There's LOTS of good plumbers on here.
