I am at my wits end to try to solve my issue. I cannot get my pump to fully prime and run at its designed GPH.
From what I understand if there is an air leak before the pump it will suck air and have the issues I am having by the pump losing its prime
Now when I say fully primed, I am talking water all the way to the top of the clear lid completely filling the leaf pot and the water fall having the normal looking water flow like in years past. This is my 4th or 5th year with this pump.
Now let me add that for an hour last night I got the pump to run totally normal. Take the lid off, pour in a quarter bucket of water, close the lid, and plug in the pump. It stayed fully primed and water flowing at its normal heavy flow. Then like it has been doing all season long is slowly losing its prime. The water level lowers inside the leaf basket and the water flow goes to a small trickle.
Now sometimes at the discharge in the pond I have bubbles. Sometimes I don't. I shut the pump off to re-prime it and the lid has some great great suction.
Everything above water level has been replaced, or taken apart and retightened. Zero water leaks. All bolts have been inspected and tightened on the pump.
Zero water leaks.
Hooked up to this pump is two 2" pvc lines coming up from the bottom drains and joining to one and entering the pump. I have even dug up several areas where the pipes run underground thinking if there is a leak somewhere underground I might see a pool of water.
I don't want to ramble on, and I have done more to try to isolate the problem, but wondering if someone else might have experienced this issue?
Thanks for any help,
Steve
