Warning for RO-only users

[scherzo]

I usually make my water in large batches. I always flush my RO membrane until the TDS reaches 0. Usually about 3-4 mins.

I have a 10 gallon ATO tank and a 25 or 30 gallon ish brute container for salt.

I've always thought about using an electronic shutoff valve at the inlet and use my apex with a float valve to turn on or off. That way the pressure through the RO membrane remains fairly constant.

This option would work for you or get a DI. I don't think I've changed my DI resin for at least 6 buckets of salt and a year's worth of ATO.

In the end you'll probably end up paying the same amount of money.

I've gone through 2 RO pre-filters since the floods began, and I've only done a single 50 gallon water change. 3 TDS is what I aim for considering the input.
