Low Flow of Water
–
Rated Service Flow is 1.6 Liters (0.42 gallons) per Minute
Possible Reason
Solution
Determine Flow of Water
Rated Flow Rate is 1.6 Liters (0.42 gallons) per minute
.
Check flow rate by dispensing into a container to measure
for one minute and measure the amount of water that was
dispensed.
Feed Lines too small
Feed lines can restrict flow if run long distances from the
supply. It may be necessary to increase the supply line (e.g.,
use 3/8” feed line vs. ¼”.
Elbows and turns in the feed
line
Minimize elbows and turns in the feed line.
Filters
Filters with high pressure drop due to fouling or just by
design. Change filters more frequently or go to higher
micron size filter for local water conditions.
Restrictions
Follow flow path to ensure there are no undiscovered
restrictions due to debris or malfunctioning valves, including
the supply valve at the source.
Booster Pump
Add a booster pump to the supply line if the feed is slower
than needed.
Bladder Tank Pressure Drop
The pressure inside the bladder of the tank has dropped or
bled off slightly, reducing the pressure output of the tank.
Recharge using the Shrader valve on the tank to 5-6psi.
Bladder Tank Failure
The Bladder Tank is no longer holding air pressure, so that it
cannot drive the water out. Replace the Bladder Tank.
