grey pipe is sch 80 and white is sch 40 or class 200. Grey is rated for higher pressures and is Only needed for looks. Sch 40 will do just fine and cost much less
Yep HD ball valves suck. Try and find a local irrigation supply store near you and buy from them. The sch40 ball valves they sell will be much better quality. All HD stuff is homeowner grade stuff. Irrigation store will be contractor grade and much better. I was a landscape contractor for a nunber of years and can tell you from experience the irrigation store will have better quality parts. As far as pipe either HD or a irriation supply stuff will be exactly the same except the irrigation store will most likely sell in 20' lengths and HD will be 10'.
well i will be keeping my reeflo dart pump and doing everything in grey pipe sch 80
would you use a other pump for 2 Two Little Fishies PhosBan Reactor 550 and one 150 and a uv ?????
Build a manifold and run the reactors off the dart. Use a separate pump for the uv. Plump the uv to pick up on one side of the sump and empty out on the return side.
