If your gutters connect to storm sewers, keep drain lines clear. Anti-backflow devices reduce the chances of basement flooding. Several types of devices are available. Check-valve devices allow water and sewage to flow away from the drain, preventing water and sewage from backing up into the drain. Gate-valve devices operate like a gate, closing and shutting off the flow of water and sewage.
Valves are manually or automatically operated.
Sump pump systems assist in keeping unwanted water out of your home. There are several types, including single sump pump and dual-level systems. A battery or generator can be used to power the pump in case of a power failure. Remember to test your system monthly. Sometimes water still gets in.
