|In response to Re: main sewer clean-out|
: : Do you know that you actually have a house trap at that point? The water would not normally rise in the cleanout pipe under any conditions other than a partially plugged main line.
: : : I had a sewer cleaning service clean or remove the obstruction in my main sewer pipe.
: hj is right about the trap. Are you sure? A house trap is rare used but your jurisdiction may have them. Probably those plugs are two directional cleanouts and they face opposite of eachother so the space inbetween can be cleaned. The sewer person needs to go through both. The C.O. furtherest from your house goes toward your house and you are right the inside one goes on out to the sewer. Water should not rise in the cleanout.LonnythePlumber.
:I have a house in Deaborn MI that was built in 1940. Wayne county has a combined sanitary and storm sewer system. My home has a double clean-out house trap inside the basement were the wastes leaves the house. I'm told by local plumbers that this was common during this period. My weep drain system dumps into the sanitary via a "sand trap" that was designed to allow the storm/surface water to enter the sanitary system, but with a back flow valve to prevent backup of sewer water into the storm system. I am currently having problems of sewer water backing into the sand trap. Still trying to figure out the problem. JK
