I'm putting an old well pump in my pond for a fountain and watering the lawn. I
think it is referred as a jet pump. I have a check valve at the end of a 20'
intake pipe. But it doesn't keep it's prime. I have replaced the valve without
sucess. Is this type of pump adaptable to this application?
The pump seems to be in good order. The verticle lift is about 5feet. The
intake is about 12" under water. While running, I can't see any leaks. One
thought was after the pump stops running, a siphon starts from the fountain end
and rermoves just enough water to loose the prime.
Although you don't describe how the fountain could siphon the water out
of the pump's wet end.... especially with no air leaks in the tubing
from the water source, which kinda makes that impossible, especially if
the pump is lower than the water outlet at the fountain. But if so, then
you should use a submersible pump. They make fountain pumps for just
I think you have a problem on the suction end of this rig. Spray shaving
cream foam around all suction joints and watch for it to be sucked in
and as you run the pump. It will make little holes or dimples in the
foam or suck a hole in the layer of foam.
