Suggestions Please

My system was fitted by K-Systems 7 months ago. The problem I have is that I am using resin like its going out of fashion. I backflush once a week to clear filters Etc. and I have recently replaced the paper and carbon filters. My TDS at tap is 316 and the lowest I can achieve after RO is 44.  I have a 700Ltr tank and therefore before tank is full my resin is creeping above 0. I am based in West Midlands(WV5) Has anybody any suggestions as to whether I can fit anything to my system to reduce resin usage?

I would speak to the supplier, although it sounds to me like the membranes are shot.

New membranes. Whats your pure to waste ratio when you are producing pure water?

By measuring the amount of waste you are sending to the drain and comparing it with the amount of pure you are producing at the same time.

There are 9 pages of info if you do a search "pure to waste ratio"

At your high tds I would imagine that you would need about 6 liters of waste water to 4 liters of pure.
