Hi everyone, I'm new to the forum as well as pool ownership so any help is appreciated! Vinyl in ground pool that is 16x32 and 22k gallons. Just bought the house and have several broken lines and I'm trying to determine what actually needs to be replaced after pressure testing. Two lines are connected to R2 underground and that is the only working line and returns. R1 is broken as well as the skimmer line. The drain and the return next to the skimmer are blocked/dead lines. I'm obviously replacing the skimmer line. Do I need to replace R1 as well or will the 2 R2 returns be enough? I want to do it right but replacing the R1 line requires breaking a concrete patio in a second place as well as adding several thousand dollars to the total price.
