Sump Pump
"I believe the placement of the check valve is important. If you place it to close to a submersible sump pump and lets say you have a discharge line that runs to a basement ceiling, when the pump is not on you have the weight of the water in the discharge line holding the check valve closed. (static head) As your sump pump starts to get old it will have a tough time pushing against all of that weight. By picking a location two to three feet off of the top of the sump pit you will give your pump an advantage as the pumped slug of water will hit the check valve and allow it to open easier due to the reduced weight of water above it. I always told my plumbers to put the check valve at belly button height." "Compressed air trapped between the water pumps and the check valves can impair a sump pump's performance or simply render it inoperative. This is a pretty common problem in sump pumps with a solid pipe that leads to the check valve. If your sump pump has a solid pipe there, cut about a 1/8-inch hole through the side of the pipe within the sump; this will prevent compressed air from becoming a potential problem for your sump pump."
