Hi, total rookie/newby here.
Question, I just bought a house that has a hot tub built in / connected with the pool. During first few months of running the filter pump, the water would partially drain out of the tub (assuming into the pool and then circulated through the filter) and then refill when the filter shut off. But now, the hot tub doesn't drain at all and is getting pretty cloudy and dirty. Any idea what could be causing this? I am assuming that the partial draining is correct?
