OK, let me see if I can describe this well enough to get some help. We have a half bath (toilet and sink) on the first floor. This bathroom backs up to our garage. In the garage, on the same wall as the bathroom, I wanted to install a utility (laundry) sink. I pulled down the drywall in the garage to expose the 2" drain line from the bathroom sink. I installed waste tee in that line, and ran 2" pipe over to utility sink. I essentially tied into the existing sink drain line for the utility sink drain. No vent specifically for the utility sink, I'm "sharing" the bathroom sink vent. Now, utility sink works fine, drains no problem, etc, etc. Almost immediately after installing this set-up, two of our toilets stopped flushing. Water would just hang out in the toilet and drain very slowly. Dumping big 5 gallon bucket of water into toilet did not cause a "flush" water still drained very slowly. Could my new install somehow of effected the ability for my toilets to drain, or is the timing just a coincidence?? _mike

ive done tons of surfing trying to solve this without bothering yall.... but i cant seem to find my answer. i just bought a house. and one of the toilets flushes very slow. takes 2 times to flush even if im just peeing. there is tons of air coming up through the toilet bowl and the tank when i flush. it wants to swirl... but it cant because of the air bubbles. things i have tried to check: the toilet guts. clogs in the little holes underneath the top of the bowl. the air vent.... best that i can the problem with the air vent.... it connects to my other bathroom in the attic. the other bathroom flushes fine. shoould i be cutting apart the pvc in the attic to try and find a clog? i can see down to the bottom of the vent when i look at it from the roof.... but the vent comes out of the roof over the other bathroom. dont care to do this without me knowing for sure that this is the problem. thanx, patrick
