hello,
i recently purchased a home. While doing some concrete work in the basement i started to notice a sewer gas smell coming from my drain in the garage. I decided that since i was doing concrete work i would dig up the drain and see exactly what was going on. It turns out that 40 years ago when they built an addition onto my house the built it over the main line trap ( which is normally outside?) and the drain was an open vent to my trap. I talked to a plumber and he thought it would be alright if i just capped it off but then i would lose my garage floor drain, but if i put a trap on top of the trap i would lose my access for snaking my main.... so i am not sure what to do. Also i wanted to replace some of the floor drains in my house and noticed they are all of the bell trap design. If i change them to p traps i am afraid of the problems that might arise from ventilation. Any suggestions?
