issue

Hey crew, LONG time listener, first time caller. We bought our house in 2021 with a 30 year old pool and I’ve learned a TON on this forum since and I’m so thankful for all of your contributions! I’ve been meaning to make a post about my pool testing but a new issue arrived today that’s higher...

I have a MaxFlo on my solar panels heating system. For different reasons, the solar system uses a separate plumbing system than the main one, handled by a different pump. The pump is activated automatically by the solar control system, whenever it makes sense based on air/water temperature...

Nearly zero psi. Return flow looks normal. I just replaced pressure gauge and washed the cartridge filters today but didn’t solve the issue. My pump basket is clean. What else should I check? Please
