Home Master® Reverse Osmosis System—Owners Manual
Troubleshooting
IMPORTANT NOTE: Before performing service on the Home Master® RO at any time, and
for any reason: first close all under-sink water valves, except for the RO faucet, which you
should open to relieve system pressure and drain away excess water from the lines. Push-
pull and quick connect fittings are nearly impossible to remove when under pressure.
Leaks from metal fittings Unscrew fittings and re-tape male fitting. Tape should be
wound 5-7 times around male thread. Tape should not cover opening. Use only Teflon tape.
Re-tighten fitting securely. Over tightening can crush the tubing insert and cause a water
blockage.
Leaks from plastic fittings Plastic fittings should be firmly finger tightened. Under
tightening can result in leaks, over tightening can crush the tubing and result in a water
blockage. For plastic fittings only; make sure the plastic tubing has an insert in the tube
end, and a feral (oring which compresses the tubing around the insert) in the plastic female
fitting. Drain tubing does not need an insert.
Leaks from push-pull or quick connect fittings Disconnect fitting by depressing the
collet ring on the fitting with one hand and pulling out the tubing with the other hand while
the collet ring is still depressed. Tubing cannot be pulled out without depressing the collet
ring, and relieving system pressure. Make sure the tubing is cut is straight, the edge is
completely smooth, and the tube is rounded. Scratched, gouged, damaged, or oblong
tubing end will leak. Re-insert the tubing into the push-pull fitting. Push tubing all the way
in, then pull back gently, to check fit. Most push-pull fittings take about a 1/3” of tubing
inserted into them.
Fine Air Bubbles/Grey Tinted Water: tiny air bubbles often accompany a new system
installation and filter changes. Air becomes trapped inside the tiny carbon pores and is
released over time, not gallons. After pouring a glass of water, allow a few seconds for the
water to clear. Enjoy!
Noises: Hissing or flowing sounds from Home Master® RO are normal during the water
purification process. Sounds should last for approximately 1 hour per gallon of water used.
Sounds should stop once the reserve tank is full. Permeate pump equipped systems will
“click” and “whoosh.” IF the clicking from the permeate pump is troublesome, then place
some insulating material between the mounting clip and the wall, such as a rubber jar mat.
A GROANING sound upon start-up indicates air bubbles in the automatic shut off valve.
This will go away with time or your can pull the Home Master® RO off of its mounting clips
and rotate it 90° left and hold it there for 10 minutes, then rotate it 180° right and hold it
there for 10 minutes while the system is operating in order to pass the air bubbles. Repeat
as needed.
Gurgling noises from the drain can be present during normal operation. Sounds should last
for approximately 1 hour per gallon of water used. If the noise is troublesome there are a
