Re: venting problems

I do not know how many fixtures you have in your house, but normally, every fixture has a trap except for the toilet. About six inches maximum from the trap you start a venting pipe. Instead of each vent going straight to the roof, you can combine them together so you have less work in the roof.If there is odor coming from the septic tank, there is a trap that is not working.
The traps are there so you eliminate odors and gases. There is a table in the CODE that tells you excactly how far the vent has to be from the trap. It depends on the size of the pipe.

Re: venting problems

your vent ist clogged and you may have a combination of clogs which need to be mechanically removed. Call a plumber.:)
