Just finished installing my new R/O. It is a Pentair PRF-RO and is so easy-peasy that that even I can do it.It's about 345TDS in and 004 out and the inlet pressure gauge now reads 65-70 psi on 1/2" tubing in and 3/8" tubing out. I get about 70 litres an hour of pure which is more than adequate.The old RO-Man type (nominal 300gpd) started at about 009 out on 80 psi on 1/4" tubing and gave about 20 litres an hour of pure.
How much was that mr gold?
What pump are you using Malc?
Quote from: DaveG on April 24, 2016, 04:26:30 pmWhat pump are you using Malc?I'm not - mains pressure only. On my old system the inlet gauge showed 75/80psi through quarter inch tubing. This gauge shows 65 - 70 psi through three-eighths tubing.

Out of interest, what made you pick the merlin over the 4040 Gold?
Quote from: Don Kee on May 13, 2016, 09:27:57 pmOut of interest, what made you pick the merlin over the 4040 Gold?I think it was simplicity and price. I'm only feeding two of us and not on a water meter ... yet.
Just to say on this, I bought new membranes for my Merlin a little over a year ago and my TDS has now risen to 42 from 14 and resin is going off quickly. We use around 1,000 litres a day. It's time to put my hand in my pockets for a 4040 I think.
