How do i connect a ball valve to my flex. I would like a valve for both my return and intake. also, what are appropriate types of flex pipe to use. thanks in advance.
I like flexable PVC because it gives the plumbing a nice and neat appearance. It also has the advantages of hard PVC in that it is not translucent so you won't get algae growth on the inside. Any harware or plumbing shop will have an array of PVC parts that you need. If you can wait I would order it on line as it is slightly cheaper and has a larger assortment.
