8. Measure water pressure.
Check at brine elbow while one faucet is wide open and valve is in backwash position.
Place the valve in the brine draw position, allowing the draw port to depressurize. Remove
the brine elbow and thread on a 1/4” threaded coupling with a pressure gauge on the other
end. Place the valve in the backwash position, open one faucet, and note the pressure read-
ing – it must be at least 15-25 psi.
9. Measure backwash flow rate.
Using a container with a known volume (1 gal bottle) check the drain flow with the unit in
backwash and a faucet running, timing how long it takes to fill the container.
Essential Gold backwash rate
≈
1.0 gpm
Essential Platinum backwash rate
≈
2.5 gpm
1 gallon / 38 seconds = 2.5 gpm
1 gallon / 60 seconds = 1.0 gpm
(Compare these results to specified backwash flow for model.)
10. Place unit at the end of
backwash and allow it to shut
off on its own.
This may take several minutes.
A slight drip to the drain is allowable. If the drip will fill the test tube from your hardness test
kit (10 ml) in less than 45 seconds, it may cause a hard water situation.
If the water is soft, follow the trouble shooting steps for running to drain. If the water at the drain is
hard and the unit is producing soft water, check the drain valve seats in level 5 for foreign material.
