We are filling up the pool. Finally!!!
We noticed that while we are filling it up, there is a very small stream of bubbles coming from one of the 4 main drains. It is small but steady. It's been like that for the past 3 hour. The pool if filling up well though.
Any idea if this is an indication of trouble or just air coming from the pipes and once the equipment is turned on the issue will go away? Should I be concerned?
