My PH- fluid sometimes is syphoned out (in quite large amounts) when the pump is shut down. I have already changed the peristaltic hose and the rotor of the peristaltic pump, but this has no effect. The (liquid)chlorine uses the same type of pump, but does not help this problem.
Does anyone has a tip what to do? Could a pool-plunger valve in the pump circuit help to break the vacuum ?
Thxs for the help!!
