Hello,
Is a check valve necessary for a sump pump installation?
..
I have about 8 ft - 1 1/2" pvc pump coming up out of the pit to a 90 degree
elbow which is then exiting the house. There is an 1/8" bleed hole at the
fitting near the pump. The pump is a high-output model than is in place
just for extreme emergencies. The pit has some small holes in the bottom to
assist drainage.
..
It seems like the check valve would hinder water flow. Therefore, is a
check valve necessary?
Thank you for your time.
