stop drinking before you type...lol

I'm assuming you're trying to say your pump loses prime over time...
1--check the o-ring on the pump basket lid...put some 'magic lube' on it.
2--if u have gate valves (the kind you have to spin to close valves) on the suction side of the pump then replace with pvc ball valves.


Before you do any of that though, wait until it loses prime again then turn the water hose on halfway and let it run over the pump lid and the valves and the male adapter going into the front of the pump...if the pump picks up then you've found your leak.
