    Anybody got the PRF RO system, sounds great, a bit pricey but should pay for itself as it claims to waste less water, any opinions?

    Mixed opinions on the merlin
    Claims to be 720 gpdwithout booster
    So seems to produce a lot of water and waster little

    Is that the same as this....
    Was looking at this when I get round to sorting out a set up..
    Didn't know if it's over kill, or a good investment

    As iv said in previous posts the waste water on this type of ro is terrible. If you watch the speed of the water comeing out the waste pipe before it goes in the drain compared to the good water it speaks for its self. Iv actually had a merlin ro unit. I use Gardiner's poles brushes and Qlock adapters and customer service next to none. I would not run a merlin if I was given one for free.

    Hi Andy

    The waste water on the PRF-RO is reduced compared to the older Merlin and can be reduced further if needed by fitting a waste valve and adjusting to about 50/50 ratio - if doing this in a hard water area you would need to open up the waste valve and run at standard ratios for an hour or so a week though.

    That's informative. If every thing was at optimum and geting 720 gpd what would be a rough estimation of water production after the mods to get it to a 50/50 ratio. Thanks

    Spoke to a "technician" at purefreedom yesterday and he said it would be no good for me because my tds is too high (300). He recommended a 450gpd unit as I only use 1200lts a week.

    Would agree at only 1,200 litres per week and 300ppm a domestic type unit would be more suited.

    This would depend on your input water pressure and input TDS.
