Cleaning / Maintenance
BackWater Valves are installed in sewer lines to prevent storm water runoff and raw sewage from entering the home during high levels of precipitation. Check valves known as “backwater valves” or “back-flow prevention valves” keep storm drainage in the sewer lines instead of allowing it into the home. Homes are susceptible to sewage backup if the lowest drain in the home is below the nearest upstream manhole. Water municipalities try to keep the lines clear, but problems can occur. In areas prone to such issues, building codes insist on the installation of a valve to prevent basement flooding.
Unlike traditional ball valves, Cyclone Valves are self-cleaning with a Adjust-O-Seal thoroughly cleans internals during CIP in the full open position. Cyclone Valves are self-cleaning ball valve also provides full, unobstructed flow and bidirectional, bubble-tight shutoff. These are significant advantages over floating ball designs, as well as diaphragm and butterfly valves.
1. Locate the backwater valve for the sewer line. The backwater valve will be near the lowest sewer line in the basement or outside, connected to the lateral line.
2. Check the backwater valve for debris clogs. Some backwater valves are manufactured with a clear catch pipe at the top so you can see debris; others have a threaded screw cap. Remove the cap by twisting it counterclockwise. Backwater caps have a square leverage nut built into the top. You can tighten a plumber’s wrench on this nut to help loosen the cap when necessary.
3. Remove debris from inside the backwater valve. Homeowners in areas prone to flooding should remove debris monthly during the rainy season. Wear a pair of rubber gloves to remove a clog as it’s likely the debris has come in contact with sewage.
4. Run water down the backwater valve to flush out the valve. Some backwater valves may have a screen to prevent surface dirt from entering the pipe and forming a clog. Water run through the screen will flush the system of surface dirt. You can pour water into the valve or run a garden hose down the valve to flush it.
