First time poster here. I did a search but couldn't find anything related to my problem.
I'm a new pool owner so most of the equipment is at this point unknow to me. I've been trying to educate myself through youtube and this amazing forum. To the point: Last night I heard a loud noise coming from the pool equipment. I didn't pay much attention because I was sleepy and the AC units are in the same area and one of them is extremelly old so I thought it was time to change it. This morning I went to inspect the noise and I found it was coming from the Jandy valve. I immediately turned the pool equipment off. Now I'm waiting for someone to take a look at it but since I'm new to this I don't want to be scammed into buying or replacing stuff that's not needed. Any clues as to what my issue can be? and will my pool equipmen sustains any damage if it's off for a couple of days while the tech takes a look at it?
