I decided to add a laundry tub to my laundry room. There was one in the past but I replaced it will just a drain pipe for the laundry the past few years. Well I decided to add one back. I hooked it up with a 1.5" pipe running to a P Trap and then running up to the laundry tub. So I set the Washer to drain in to it. Well I ran the washer and now the tub is not draining out. no other fixtures in my house are having issues. Do I need to add venting or something? Why will it not drain? PLEASE HELP . Note I did auger out the pipe prior to hooking up the sink and it seemed OK.
THanks in advance for helping the newbie. GReat site by the way.
