Check valves
What is involved in having a check valve installed in a sewer line, and how much is this likely to cost? Is it something that can be accomplished from inside the basement?

i’ve been trying to have this done for about 3 years. good luck finding a plumber who will do this work for you. they just want to do the easy jobs like charge $300 to replace a rusted out sink pipe. i’ve called ten or more plumbers and they all suggest every possible alternative in the book rather than just doing this job. then once they realize what you’re after they stop returning your calls, to keep focusing on the low laying fruit. dripping faucets, etc. if you do find someone pls follow up here as i flood at least once every 3 months.
Checkvalves prevent water from backing up from the sewer into the drainage system for buildings and houses. They work when water/liquid flows in rather than out. When that occurs the check valve closes and will prevent the back floowing water from entering the drainage system of the building or house. The check valve is held closed by the pressure of the back flowing water. The only potential drawback to the use of back-flow valves is that when they are being held closed by the back pressure of the back flowing water, they will not allow any water/liquid to be discharged into the sewer. In most instances this is not a problem as the piping in the house or building will hold the water/liquid generated during the time that the back-flow valves are engaged. Then when the back flow valves release, the held water is discharged into the sewer. In private home applications the use if clotheswashers and dishwashers should be limited until the back-flow valves release.
In applications where roof drains and run-off storm water empties into the building’s sewer, plumbers will generally install a 1,000 – 10,000 gallon holding tank – depending on size of building (most houses would use a 1000 – 1500 gallon tank. Depending on application, installation of back-flow valves will generally run $2,500-$4,000 more if a holding tank is required. This is somenthing that you should do your due diligence on.
