Best way to plumb Dart for a CL

[craftytony]

I have seen a 120 setup with a dart used for the closed loop and it was so quiet I didn't even realize it was on...

follow up question on this topic...

i am plumbing a dart from 2x1.5" intakes through a"T" to the dart and will probably use a double wye to split the flow three ways for 1" returns. i will use glue flex pvc most likely.

are there any spots along the plumbing where gluing is not recommended and threaded connections should be made instead?
and...where should i have ball valves?

Install true union ball valves on both ends of the volute. Get some threaded nipples for the pump side, cut the other end off and glue it to the union. Use LOTS of teflon tape, those Darts are hard to get the threads to seal. Customaquatics sells George Fisher true union ball valves in large sizes at a decent price. 1" and 2" Sch 80 nipples can be purchaced at a good pool supply shop.
I would avoid any threaded connections if at all possible...they can leak(usually very slowly) or fittings get cracked from over tightening.

The housing for the impellar is also known as a volute.

this may sound like a stupid question, but i gotta ask....

primarly due to cost, i am considering using regular pvc for the closed loop plumbing - is it louder than using flex pvc?

also, should i test the closed loop before i glue any parts?
