Trouble Shooting Guide

Probable Cause
Solutions
No water or not enough water
1. Feed water shut off
2. Storage tank valve shut off
3. Plugged or crimped lines
4. Pre-filter cartridge clogged
5. Low feed water pressure
1. Turn on feed water
2. Open tank valve
3. Remove blockage or crimp in lines
4. Replace pre-filter cartridge
5. Feed water pressure at membrane must be at least 50 psi
Low flow rate from faucet
1. Low air pressure in storage tank
2. Storage tank valve partially closed
1. Increase air pressure to 7 psi in storage tank with product
water drained.
2. Open tank valve completely.
High product water TDS
1. Insufficiently flushed filters
2. Increase in feed water TDS
3. Membrane life expired
1. 5 gallons (approx. 2 full tanks) must be drawn from spigot
to sufficiently flush filters
2. Contact dealer for revised product water TDS
3. Replace membrane
Bad Tasting Water
1. Taste from glass or plastic containers
2. Post carbon filter cartridge exhausted
3. Storage tank and/or system contaminated
4. Membrane life expired
1. Contact dealer for explanation
2. Replace post carbon filter cartridge
3. Contact dealer for assistance
4. Replace membrane
Cloudy water
1. Dissolved air in feed water gets concentrated in product
water.
1. Condition usually clears up eventually as feed water
changes. Letting water stand will allow dissolved air to
dissipate.
Cloudy ice cubes
1. See cloudy water
2. Certain ice cube shapes trap dissolved air more than
others. The larger, more squared off cubes are cleared,
smaller rounded surface ice cubes are cloudier.
1. See cloudy water
2. Change ice cube mold shape, make cubes manually if using
automatic ice cube maker, let stand to release dissolved air
before freezing.
