One used Vertex Puratek Deluxe 4-Stage 100GPD RO System.
Notes:
- Bought it used as a backup few years ago.
- The pressure gauge makes a vibrating reading which can’t be read, but the booster pump is working.
- The booster pump is not made by Vertex but a different made in China brand.
- All the filters and the membrane had been replaced few months ago.
- Make 5G RO water in about 50 minutes, that is just about 100GPD.
- I like the fact that without power the unit won’t work, so you can add a timer to limit the damage if and when overflow occurs.
