How do you know if the vacuum relief valve (VRV) is not actually relieving? We used rubber elbows to match the rubber couplings in the roof/panel plumbing. The VRV is in the return line high point (left side, red circle), but when the pump turns off for the day, the high point rubber elbow sucks in (Right side, yellow square). Puffs right back out when the pump goes on again.
That can’t be good, right?
Should I replace the rubber elbows with ABS or should I put in a new VRV? Or other, better ideas?
