any reason then folks why my output is still the same after 2 years ?? ? ?? ??

This is what I'm getting at I change my filters when I'm told to Matt doesn't change hiss for 2 years and the out put is still the same .. a very low tds count

Its all to do with the tap water in your area.  Seems like Matt's water is very soft and his water treatment system has very little to do.

peter, its not, its 460 from the tap

[matt]

allthough i only use 100 - 150 L a day for 3 days a week

And mine is 430 at the tap   

[matt]

out of interest, how much are the prefilters to buy ?? ?? ?

[Chris Cottrell]

set of three are i think £15.25inc vat on ro-man site plus del

OK confession time  

I have a 200gpd Ro-Man unit.

Use around 3000 ltrs a week and I haven't changed the prefilters in the year that I've had it.  420ish TDS in and still gettiing 5 or 6 out as I always have.

If I get a year out of the membranes and prefilters at what they cost for the water I get out I am happy. Its probably down to what chlorine levels are in the water. As I said before the only purpose of the carbon filters is to get rid of chlorine.

In my defence I do flush VERY regularly..  shame on me.

so just over 20 quid

thats not bad every year i guess, BUT if i get 3 years out of mine, its been worth it

i dunno, i would change them every year if i was folk

[007 or what]

Hi andrew what is your water presure? I also have a 200 RO but i'm only getting 1750 litres a week, including wkends.

[Andrew McCann]

Hi  007

Mine is marginal at 50PSI.

In truth I am getting around just under 500 ltrs per day (24 hrs) from it at the moment.

During the summer its nearer the 650 mark.
