My auto fill float valve sounds like a toilet running all day everyday. I just bought the house and I don’t know if there is a master valve to shut it off. The old owner has dementia and has no idea. There are no gate valves near the float valve and there are no fill/gate valves near the pool equipment. Is it typical for this thing to run all the time? It was not running when it rained the other day. I am in Central Valley California.
