Does anyone on here use a permeate pump with their RO?
Permeate Pumps
I've had one for almost two years and it works quite well at increasing the output from my RO. It only works with the smaller RO models ie; 100-400gpd models as they are not designed to work with the bigger ones.
What I don't understand about it is this; if it works by using the pressure of the waste water from the RO, why when I raise the waste pipe coming out of the Permeate pump above the height of the pump body it stops working even though waste water is still coming out of it?
It's no big deal as long as I know that it works when I lower it, and that's how I have it set up anyway. It just mildly irritating not knowing why. There is nothing about it in the instructions. They indicate that as long as it's plumbed in correctly it should work irrespective of where it's located.
It's quite a good piece of kit because in simple terms it creates a negative pressure environment on the output side of the RO making its easier for the water to be pushed through from the other side. I don't know why but it has dramatically improved the effectiveness of the RO so that the water coming out of it is only .003 tds instead of .015 tds. It comes out of my tap at .400+ most of the time. This means my 10inch resin canister last ages.
