I'm new here. I'm also new to pools having moved from a colder climate where we don't really have them (Great Britain).
So this is the situation. It's an outdoor pool serviced weekly by our pool guy. I noticed recently that there was a tide mark on the top row of tiles and also I bit more "flotsam" in the pool little bits of debris nothing serious. I checked insider the chamber on the where the strainer basket is located and noticed there was no water movement so guessed that there was probably a blockage or something.
I went around to the pump and it was humming in the usual way and I looked inside the glass inspection window and it was dry, much to my surprise. The waterfall was operating normally so I assumed, probably wrongly, that if the waterfall was working there was water throughput in the pump. So anyway I shut off the pump at the breaker.
I was told by somebody that the waterfall would stop whenever there had been a pump problem and that the pump screeched when it had blown in the past. I also took reassurance from the fact that a pool guy attends weekly and would have hoped he would bring any issues to my attention. It is a relatively new pump I should mention.
My my question is, obviously I was given bad information and in seeing the waterfall operating I assumed pump was all okay, so what is the likely scenario here? There is only one pump by the way.
Thanks in advance!
