Forum Title: septic holding tank pump
Recently I replaced my pump in the septic collection tank. However the new pump runs but won't pump out of holding tank, only swirls water. If I play with switch by turning pump on/off rapidly, the pump starts to move water out. My septic tank plumber says my beds are full and need to be replaced. However, since I can get the pump to work by turning it off/on, I think the pump is not strong enough to open the backflow valve. Could this be the problem or is the plumber right and I need to replace my beds.

I did not replace pump but was done by plumber. He did not replace the check valve but used the existing one. I am in Tennessee and the system is 28 yrs old. The valve is in a horizontal position. Don't have a picture and can't get one as it is down about six feet.

i never change out a pump with out changing the ch valve cut the line, above the check, see if it will pump out with out moving water to your drain field i suspect the ck valve is the reason the first pump needed switching

what kind of check valve did you install spring check or swing check? is it installed on the vertical or the horizontal it has an arrow on it, which way is it pointed ? toward the pump or away from the pump?
