ViewFrequently asked questions.
Does a backwater valve stop all flooding?
No. It addresses sewer backflow, not every source of basement water.
Is maintenance important?
Yes. Follow the manufacturer’s instructions so the mechanism can operate properly.
Are municipal subsidies available?
Programs vary and change over time. Check directly with your municipality rather than assuming eligibility.
