New to this forum and thought I would attempt to get some basic trouble shooting advice. Somehow my system is getting air in it. I read a previous post to start with filter basket o-ring and apply silicone spray. Is this silicone spray the all purpose variety you can buy at big box store or something more specific to o-rings? Thanks. I have lots of bubbles on top of filter basket when the system is running.
At night when the pump and filter are off I get crazy bubbling sounds that appear to be coming from the pipes that attach my system to the solar panels on top of my roof. Sometimes this bubling noise goes on all night! Maddening!
I had my Pentair pump serviced last year for whining. Shouldn't the tech have lubricated the o-ring when he re-installed? I asked him about the bubbles and he seemed pretty clueless. When the pump and filter come on in the mid-morning, lots of bubbles come out of the returns and often when the weather is nice, the water is very hot which makes me wonder if the issue is with the solar heating system.
Thanks for helping a novice out.....appreciate your ideas and suggestions!
