Does anyone know of a brand of check valve that is not spring loaded or does not stick as much others?
I have tried to put a check valve inline of my shower sump bilge pump
, so that after pumping, the sump does not partially backfill. What ends up happening, especially if not used for over 1 day, is the pump runs and does not actually begin pumping until I take off the grate, reach under and shake the check valve and hose. I presume the check valve is spring loaded and sticky. I have changed bilge
pumps to no avail. It is a small rule bilge pump
which has plenty of capacity for its job.
Of course not a thrilling proposition to go elbow
deep in shower water
after supposedly cleaning
