Vented Sewer Cleanout?
Posted by alan burchfield on December 29, 2003 at 15:41:28:
Hi, my plumber has recommended that I have them install an external cleanout. This makes sense as my current cleanout, in the garage, is about 80' of pipe away from the street. They also said that with this cleanout, if we ever have a mainline backup again, then the overspill would be there, rather than in our shower/bath. So my question is: will this cleanout have some kind of vent/valve to allow overflow external to my house, and if so won't the sewer gas smell outside the house??
