hi I have a 4040 system and seem to be getting 29 ppm after the ro, it used to be about 12, I am over due changing the carbon and sediment filters so could the be the cause of the higher ppm reading, and might this of damaged the ro membrane.
Also I live in a low water pressure area ( takes 8-9 hours to fill a 500lt tank ) would I be best with a HF4 or HF5 membrane. Not really wanting to add a booster pump for the moment. Thanks for any help
