Oh yea I forgot to mention, use lots of teflon tape to seal the screw in 2" pvc fittings going into and out of the pump. The fittings alone would not provide me a leak free seal...

The three quick disconnect fittings in the picture work great when you need to disassemble or service the system. One more thing, try to use as few 90 or 45 degree fittings as possible. Also don't use "street" 90 degree fittings aka "street L", they make a 90 degree bend in much less distance than a regular 90 degree fitting. This helps to reduce the hydraulic friction losses.

P.S. I know that I don't follow my own advice about minimizing 90 degree fittings.
