RO replacement

Hi Guys (n Gals)

Needing to change membranes as tds rising. There is a lot of variations out there - Voytron, CSM, Filmtec ect, all with a wide range of prices. Anyone any info on quality and efficiency? looking at 4 X 10" units at min 100gpd running through 80 psi. boosters Preferably 150 gpd.

It seems you can run low pressure units through a pump, any thoughts?

Thanks

Gerry

What is your tap TDS , I am lucky living in a soft water area so I get by with a simple 450gpd RO which cost me £180.00 inc VAT from daqua.co.uk , Doug is a top man and you can get all you need from him .

385 at tap and heavy with limescale, gone up to 45 after membranes, usually get 25 so going to change all filters and restrict or valve, been looking at low pressure membranes and won't go for cheapies.

Thanks for reply Gerry
