I have an old, simple setup. Two black poly lines coming in. One from main drain and one from skimmer. They both have a barbed hard 90 elbow coming off the black poly that turns them each into an old brass gate valve. Then they connect in the middle with a tee and go into my pump with pvc. All 1.5" lines. I bought stuff to swap this setup and but want an opinion before I do the work.
New setup will be a barbed connector coming straight off the top of the two black poly pipes. Threaded so I can screw on a piece of pvc. Then I will glue a softer 90 onto that. I will connect them in the middle with a 3 way Jandy valve. The two lines coming into the Jandy valve will be 1.5" pvc. The single line coming out of the jandy will be 2" with a union and go into my pump. Sound better? I would just leave it but I have air coming in somewhere. If it was my pump seal would I be seeing water on the ground by the pump?
