alright ian i flushed out for an hour today and checked tds direct from ro its reading 118 seems really high. I am in a really hard water area northants. how long should the resin last before having to change it anyway. Im using around 250 litres a day. Im not sure what ratio system is set at theres just a dial which you turn to open up or send more to waste im sure im sending plenty to waste. Any ideas alex or ian? If i need a water softener how does that work? I will be ringing pure freedom tues ive had system for nearly 6 months whats the live span of a 40 ro?

Hi tatman

Yes you are doing the right thing testing the water before it's going into the resin vessel.  118 tds is ridiculously high after going through the RO - there must be something wrong.  Either the membrane isn't seated properly in the housing or the membrane isn't working correctly.  Either way, get back to the supplier and I'm sure they will be able to help you out.
