POOL plumbing leaks. I'm tired of messing with it so it's time to redo it all. So I brought out a pool professional and got his advice and been googling ever since. He said dig up All my pipes as far as I can. That's done. He said buy a new filter. I had a 20 year old single cartridge Hayward that leaked. I got a new Hayward c4030 swim clear. I have a 1.5hp Hayward. I have a skimmer a pool drain and a sideboard that's been capped and the three returns on 1 1/2-in pipe. I was told to do it back as far as I can and change everything to 2-in. Returns and suction side. And open that cap side port up and use it for my robot vac that I currently hooked to my skimmer. I want to do it all myself so that I can afford to buy all the stuff I need. But I need some advice. The attached pic is what I got and I want to redo it all.
