Another question please?
I'm not sure if I should keep this all in the same thread, if so I apologize
I noticed when looking at the pressure valve for the sand filter while it's running normally is less than 5 PSI (it fluctuates, but looks like between 1-2PSI)
I also notice air bubbles coming from the return lines, so do these 2 things in combination show that I have more of a problem than I think?
I read the solution about a new pump o-ring, so I will get a new one in the morning. Is this indicative of any other kind of problem?
