I've been reworking some of the plumbing to my pool - the previous owner installed 3 valves about an inch from the ground, which prevented one of the valves from being able to be opened all the way.
So, in my infinite wisdom, I cut the pipes, and moved all 3 valves about 3 feet off the ground.
My issue, is that the pump (Hayward Max-Flo XL) now has issues priming - to the point where is just won't - even if I pre-fill the basket with water etc...
Did I place the valves too high?
I can also see a lot of cavitation in the basket of the pump (through the looking glass) - and aside from a small drip in the return pipe, there are no visible leaks. I also checked the little o-ring in the joint which attached the pipe to the pump, and it is seated correctly.
Any help is appreciated.
