I read that if my pump is spewing out bubbles, that there must be a leak in the piping leading to the pump's input, because those pipes try to suck in surrounding air. My system has bubbles, but not from there.
- When I out to the solar heater on the roof, there are tons of bubbles at first, but still quite a few hours after settling.[/*:m:3e9s6k7v]
- When I bypass the heater, there are no bubbles.[/*:m:3e9s6k7v]
- The inputs to the pump do not change in either case.[/*:m:3e9s6k7v]
Below is a photo of my control system. The 3 valved pipes coming up from the ground feed the pump.
When I divert water through the solar heater (on roof in a photo later in this thread), I get bubbles, but that is a pressurized line -- it is forced water FROM the pump. Where could they possibly be coming from?
I have no water leaking from the roof or the piping leading to it. Being pressurized, wouldn't it leak water rather than taking in air? I don't get it. Any ideas on how to diagnose this are appreciated.
