Sorry for the delay in replying Matt, our little boy crept into the study and managed to totally wreck our hard drive on the computer! £380 for new computer and lost work as it was all on George, which I've managed to reload so out today ok.
Water production is actually fabulous, never thought I would be able to install a system but now producing all that I need at 000tds.
I keep checking the inline tds meter as I still cannot believe it.
I do know that if I increase my workload then I'll have to buy the upgrade kit, but at the moment I could produce around 200 litres a day, which covers my upper floor windows.
Do you leave your pump on when back flushing the membrane?
Thanks for asking how I was getting on.
Regards
Chris.
