Troubleshooting

Note: To remove tubing from quick connect fittings, hold in on the small col-
let ring at the end of the fitting, push this ring in towards the fitting while
gently pulling out on the tubing. This releases the tubing from the fitting and
it will slide out easily

*Water output will decrease as the tank empties and will only be a quick drip or slow
stream when the tank is empty. This is normal.
**Water will run down the drain whenever the system is filling the tank. How long it
runs depends on water pressure, filter and membrane condition, membrane size,
system configuration, and amount of water taken from the tank. Average times for
refilling the tank range from 30-45 minutes for a couple glasses of water up to 4-5
hours to completely fill the tank.
***The standard tank will hold a maximum of about 3.2 gallons of water, the up-
grade tank will hold about a maximum of about 10.3 gallons of water. Actual storage
capacity may be less depending on system configuration and water pressure.
Solution
Ensure water supply is turned on
Use booster pump if pressure is <40psi
Single gasket needs to be facing up
Replace filters
Replace membrane
Replace check valve
Replace auto shut off valve
Ensure valves open & no kinks in lines
Trace flow of water to pinpoint cause
Use booster pump if pressure is <40psi
Replace filters
Replace membrane
Replace Check Valve

Trace flow of water
Check pressure in tank, min. pressure
4psi, max. pressure 10psi, with tank
empty.
