6. Hot Water Coming out of Faucet Vent Hole
Possible Reason
Solution
Improper tubing attachment from
the tank to faucet or vice versa.
Verify tubing is connected properly from tank outlets to
correct faucet attachments.
Hot Tank outlet hole is scaled over.
Inspect and Descale Tank as needed.
See Hot Tank Descaling Instructions that are included
further below in this Troubleshooting Section.
See instructional video on the Partner Area of the
Waterlogic.com website for more information.
Expansion chamber is not sealed
properly.
Replace the Hot Tank.
7. 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 to measure
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 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.
