What prevention techniques can I use so storm water and wastewater don’t end up in my basement?

One of the best ways to reduce the risk of storm water and wastewater from entering your basement is to have a plumber install a back flow valve on each line. These valves work when either the sanitary or storm water mains are surcharged (full). The valve will then close and reduce the risk of water entering your home from the storm and sanitary mains. When the valve(s) are closed, it also does not permit water to leave your house until the mains are no longer surcharged.
