Hi Guys..

My tds reading is 340 from tap and after RO it's 14-15, so not too bad. Is there a calculator online, to show how long resin will last? Or are there any clever guys here that can work it out?

On avearge, I use around 500 litres a day...

thats roughly the same as me but we use about 800lt a day and a bag of resin lasts over a year, gardiners website had a resin calculator on it but i cant see it anymore but to be honest it wasn't that accurate.

our water starts at 450ppm, then after RO comes out at 012-014ppm,

we have a 1lt di on the end that lasts us upto 2 weeks. would last longer but we only work with the water on 000ppm, unlike some people that work upto 010ppm.
had one bag of resin last us over a year now,

our filters are changed every 6 months and membrains have been in fro 2 years now,

maybe look at changing filters/membrains too?? or flush longer as you water is lower than ours but coming out higher than ours!
