So, recently, we’ve started noticing gurgling in our rooftop solar return line.
I’ve googled a bit and think I have the problem narrowed down, but I was hoping for a second opinion.
The gurgling is definitely in the solar return line (it shakes, even). There’s some air in the pump basket, but not a ton (the water gets up to maybe 1/2” from the clear lid).
I tried snaking the line from the skimmer to the pump, in case of a clog, but found nothing. I also checked the impeller for clogging/debris. Same there.
Opening the valve on the solar return, the pressure is pretty low.
Based on my research, I’m leaning toward a bad vacuum relief valve (it’s the kind that looks like it has a tight-packed bundle of wire on it), but I’d appreciate any advice.
