Hey guys Im hoping you can give me a push in the right direction here.. Our tub over the last 2-3 weeks has not been draining all the water out after use. Sometimes it will go out after a couple hours and other times is goes no where. The sink, toilet and washer don't seem to be having any problems overflowing or anything, sink does go down a little slow though, all those go into the same large drain pipe but all enter into the pipe seperately. A few things I have tried is drano which didnt work, I removed the plug and the lever unit thinking it got gunked up around that but that is ok. Ive plunged for a few hours now and nothing seems to be moving. Oh Ive also tried a snake through the plug lever pipe but it just hits the trap.. Im sort of out of ideas other then taking pipes apart in the basement, I have average plumbing skills but this one might be over me a bit.. Any help would be appreciated..
