    I am thinking of buying a Merlin PRF RO 720 - system - Has anybody got an opinion - do they produce 700 gallons per day under normal 40 psi domestic pressure - or is it sales hype - I need about 1000 litres a day - has anybody got any views - feedback appreciated thanks Terry

    I have been looking at these as well, the old version was terrible from what I can gather, but the new is supposed to be good, but hard to find any decent information.

    A moderator on another forum has recently purchased one. Here was his 'review.'

    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.


    Now I would never have believed the efficiency of this new Merlin replacement as the previous ones were very inefficient. He's happy, although he does have higher than usual water pressure.

    It will easily supply 1000 liters a day (24 hours).

    Another cleaner in town has the old Merlin. As our water can be badly laden with sediment he has fitted a 10" inline sediment prefilter before r/o to prevent sediment blocking the carbon block prefilter.

    This r/o has 3 chambers, the 1st is a carbon block filter and the other 2 are for the membranes.
