Installation Guide

2) Sluggish Flow At Dispensing Faucet

- Insufficient water pressure (see “RO Basics” for explanation) —> Check water pressure. If too low for this

chosen RO model, either increase your water pressure or add pump to RO system.

- Input water to RO is blocked —> Make sure Feed water valve is fully opened and unhindered.

- Tank not filled yet —> Wait until tank is more filled, takes 2-3 hours average.

- Low tank pre-charge pressure —> Raise tank pre-charge to 5-7 psi.

4) Tank Takes Long Time To Fill (does not meet claimed GPD)

- Insufficient water pressure (below 50 psi for non-pump systems) —> Increase house water pressure or

add an appropriate pump to system.

- Low water temperature (below 77 degree F ) —> Increase house water pressure or add pump to com-

pensate for low (cold) water temperature.

Claimed GPD:

The claimed gallon per day (GPD) flow rate for each RO model is rated based on 60 psi input water

pressure at 77 degree F water temperature. At this standard water pressure and temperature, the ROES

UV-75-SS gpd system should make about 3.1 gal of filtered water per hour, the 4-gal tank should fill in

1-1.5 hours.

Lower water pressure and colder temperature will slow the system’s output to less than the claimed GPD

flow rate. Please check your water pressure as the first step in determining the cause of slow flow rate

(low GPD)

5) Filter Housing Is Leaking

If you are experiencing a leak from any of the pre-filter housings on the reverse osmosis system, the

rubber O-ring needs to be replaced. The filter housing must have an O-ring in order to seal properly.

Please review the steps below to address a leaking filter housing.

Please follow the steps below:

Step 1. Shut off the feed water line to the RO unit.

Turn off the tank ball valve by turning the

Blue Cap on the tank ball valve 90 degrees.

Step 2. Use the filter housing wrench to unscrew the filter

housing that is leaking. Make sure the O-ring is

seated correctly inside the filter housing groove.

You may also want to apply some lubricant around

the O-ring. This will help secure the O-ring in the

filter housing groove.
