6.
Low Flow of Water – Rated Service Flow is 1.89 Liters (0.5 gallons) per
Minute
Possible Reason
Solution
Determine Flow of Water
Rated Flow Rate is 1.89 Liters (0.5 gallons) per Minute.
Check Flow Rate by dispensing into a container for one minute.
Measure the amount of water that has been 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 versus 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
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.
7.
Hot Water Intermittently Forced Out through the Faucet, or a Dual Stream
out of the Faucet
Possible Reason
Solution
Mineral deposits on the
expansion slot inside the Hot
Tank vent chamber which
blocks the normal path of
water to expand.
Descale the Tank.
