pump piping

[CarlD]

I think Poconos is right. If those 90 deg bends coming out of the pump aren't Sched 40 or better you have little chance of them standing the pressure. Those are only drain strength. EVERYTHING you use on the pool should be Sched 40.

You'll have to try working the routing to the filter differently--of course, if it's the PVC to the black fittings on the filter that's failing, you'll need some sort of PVC to ABS adaptor to make that work.

Hi,
I work with PVC on a daily basis and your problem is definately that you are using DWV fittings on this pressure application. When you go to get your new fittings, make sure that you specify you need them for pressue. Even DWV fittings are schedule 40 but there is a big difference between the fittings made for drain, waste and vent and pressure applications.
Hope this helps.

well, changed it out with the pressure fittings. plus got clear primer. duh! sure enough took 10 minutes, let it set for an hour, and she is cranking away. pressure in the 50 psi max cartridge filter is 33psi. looks like stronger circulation at the pool so hope the powered cleaner works better. plus the pump runs much cooler to the touch than the super pump.
well thanks for the help. not too often this "ol dog" learns new tricks!
