- [About RO GPD Ratings] GPD ratings are based on tests performed under specific water conditions (Urban tap water, 25°C / 77 °F, 100 PSI). Every time the temperature drops by 1°C / 33.8°F, the GPD Rating drops by about 3-4%; every time the pressure drops by 1 PSI, the GPD Rating drops by about 1 - 1.5%. For example, a standard 100 GPD RO membrane, at a temperature of 10°C / 50°F (or a pressure of 50 PSI), the GPD Rating is about 50.

## Questions & Answers

**Q: Does it constantly discharge reject water even when your not using pure water**
A: YES, you need to close both outputs or water will discharge from the brine. To stop it from running constantly most use an ASV (Automatic shutoff valve). You will also need a flow restrictor on the Brine, sized appropriately for the RO membrane

**Q: what is the wastewater to purified water ratio? can the flow restrictor be bypassed to flush?**
A: The purified water to wastewater ratio is 1/2.

**Q: Why waste water line seems to be running a lot of water ?**
A: Waste water is usually 1gallon RO/DI to 2 to 4 gallons waste. I brought my waste to 1 -2 gallaons of waste to 1 gallon Ro/DI with a booster pump. I also added and upgradeed from 100G to 200Gallon system. Just added another 100G ro/di canister.  use the waste water for plants, and garden. If ypu can get waste tube to go out and into a diffrent barrel or yard, you can recycle it. booster pump helps to reduce the waste, unfortunately there is no other way to completely reduce it to zero. good luck.

**Q: Can you suggest asov for the 400g system?  it has 3/8 input x 1/4 output - all of the asov on amazon are 1/4 x 1/4 or (rare) 3/8/ x 3/8**
A: Chemo “Harrington Plastics “ online
