I'll try to keep this short. I've got the PBs coming next week to open my pool. (I'm a new owner.) I took a walk out to inspect the filter/pump/heater apparatus this morning and found that one of the many pipes had a huge longitudinal crack with displacement. See the pics. The pipe in question feeds the same channel that my gutter pipe is going to.
What is this pipe? Where is it taking water from and how critical is it? Any guesses as to what could cause this or how it can be fixed? Should I trust the PBs to diagnose and correct or is this a DIY job?
Any help is appreciated!
