Well after having no power for 3 days straight and not prepering our pool here is the damage. I have a cracked filter housing and a cracked 3 way jandy valve. Going to use the opportunity to completely re-plumb the system. We have an old gas heater that no longer operates that I will be removing and throwing away (but would like to leave space to later install one). I think I decided on the pool filter I will be replacing the old fns plus with (pentair quad de 80). Any tips or advice on simplifying the system? I read somewhere to replace the 3 way jandy valves on the suction side with 2 ways for better control.
