Well, I'm stumped.
I've got this 1/4HP Hayward pump that simply will not draw water.
I've removed every factor in the system down to the bare minimum, replaced everything in the system that can be replaced and applied silicone lube to everything that can't.
I have a six foot length of new hose sunk into my pool that runs directly to the pump intake (bypassing the pool skimmer and filter).
I've greased the one O-ring on the intake. I've greased the O-ring between the basket and the pump.
I've pulled off the pump head, and inspected the manifold and impeller for debris.
I've checked that the impeller is spinning.
I've taken off the outflow, so it should shoot straight up into the air directly from the pump. When I turn it on, it shoots a half gallon of water up - the half gallon that I primed the basket with - and then barely dribbles after that.
There is literally only 6 inches of system left. From the pump intake to the pump output. It literally will not lift the 6 straight inches from the impeller to the outlet.The only thing left is to bypass the 6 foot length of hose that runs 2 feet up out of my pool and down 2 feet into the pump. I am sure that, if I opened the basket and poured water directly into the basket, the pump would shoot it out straight up. But if it's just that it can't draw a mere two feet of head from the pool, it's certainly not functioning.
I find the bearings on these things go yearly, and it's more cost-effective to simply buy a new pump every couple of years (~$250), but this year there's nothing wrong with the bearings.
Help.
