[Pure Glass]

Just doing a resin change and though I'd check my ppm from my garden tap.

It's shot up to 498  

Anybody got ppm as high? This is my first resin change after a year, but I do flush for a good 20 minutes every night and change pre filters every 3/4 months.

First resin change in a year ..what RO are you using ?

[Pure Glass]

Standard 4040 from pure freedom. I make around 2000 litres a week. 10 bar pressure when flushing, 60 bar when booster pump kicks in, as I have low tap pressure

Steve mine is nearing the 500 mark also.
it does go up and down a bit, I guess this is depending where the water is coming from.

I flush before everyfill also

I use 4040 also. Changed one vessal of resin once in 18 months   on twin di each tanks a sack each. (although I did replace both 18 months ago so not a true reading although I wish it was

Its an indication that the water is coming out of bore holes.

Just measured mine in Milton Keynes and is 478, not good as they say dont drink your water if it's over the 500 Mark..!

60 bar is 900 psi. Do they really run that pressure?
