I am a recent victim of Aug 4 sewer backup in Oakville and want an inspection and quote on the installation of a Mainline valve. The last cleanout(s) are located in my cold cellar – there are two cleanouts that I was told one was sanitary and the other was storm!
I have since been advised that it more likely that both are sanitary and will be joined. Point being, do I need to have 2 valves installed or do you join the pipes then have only 1 valve.
I have been advised to have a camera inspection to confirm?
What do you guys do?
