does anyone know how many litres of water you can produce from 1 tank of resin not sure size of resin tank but about 18 inches water is =66ppm
water out is 0ppm
i have been spending ages on windows as this is my first week but some windows are still drying in as though we have just had a heavy shower of rain and runs dry in white ish

its not your water causing this, as you state water out is 000tds. with water in at 66ppm it will last a fair time. my water in is 105ppm & my 10ltr resin canister lasts approx 6-8 weeks (filled 3/4 full). I use 2 canisters in sequence though (for resin economy). when i only used 1 canister i would get about 4 weeks. i use wfp nearly every day & run a 400ltr van system. my very first clean with wfp dried all white on the glass, i put this down to all the hoses beeing new & maybe it was flushing the crap out of them. after a couple of windows it was fine.
it is probably more likely your technique that is the trouble, with being new to wfp, me personaly i never clean the top frame of a window for the reasons your experiencing.
hope this helps

To work out how much pure water you get from a 25 kilo sack of resin is
your tap water tds readings divide this by 500000
So with a tds reading of 66 you will be able to produce 7575.7575 litres of pure water
If you want to know how much pure water 1 di tank of resin will produce then you need to know how much resin it holds.
You then times the amount of resin in the tank by 303.0303 this will give you the figure you want.

Williamx,
I tried your calculation and didn't work? My tap tds is 032ppm. So how many litres will a 25 kilo sack produce?

With a 32 tds reading do the following
500000 divide by 32 = 15625 litres of pure water from a 25 kilo sack of resin or15625 divide by 25 = 625 litres per kilo of resin
