I've set up my 300GPD RO, with pressure gauge, still flushing through the membranes, but the gauge after the pre filters says 100 PSI!! The needle isn't stuck either, now and then it moves a little tiny bit. Last time, quite some time ago, I just hooked up some pre filters and the gauge, and it was about 79 PSI.
Though still, I can pee 4x faster then the pure water is coming out, I'm gonna measure it in a minute. Will it increase when the membranes are flushed clean from that preserving chemical?
I mean, I've got a shut off manifold fitted as well, but I don't see how that can up the pressure like that.
Luckiest person in the UK? 100 PSI, that's fantastic if really true, I know there is a water tower 5 min from here, but I thought they didn't use them any more.
