I have a single old leaky gate valve in front of the manifold for my 3 return jets for my 30K gallon pool. Each of my supply side feeds (2 skimmers, bottom drain) have recently replaced ball valves. Question is: Do I need a valve in front of my 3 return jets? Not sure why I would ever use it and its just one more thing that can go bad. Any advice is appreciated.
Thanks!
Thanks!
