Hello! Newbie to TFP here. Pool guys installed a salt water chlorinator but gravity and the design of the plumbing has taken its toll - there is substantial leaking at an elbow joint. My questions are: (1) any tips on the proper replumb design? and (2) can a regular plumber come out and install new PVC pipe? My pool guys aren't available and I don't want to lose any more water. Many thanks!
