Misaligned, damaged or
missing o-ring
At Cap: Misaligned, damaged or
missing o-ring
Cracked housing due to excessive
water pressure issues, misaligned
filter cartridge in housing and/or
overtightening
Leak at cartridge housing,
Leak at membrane housing,
or UV housing (if applicable)
•Locate and align O-ring into groove inside cartridge
housing,
•Same for o-ring in membrane or uv housing caps
•Replace simple o-ring part for correct housing
•Replace housing part (item # h-filter, h-membrane, or
h-uv) and correct issue that caused the problem (no
plumbing needed)
Trouble Shooting Guide - Reverse Osmosis Systems
Water supply is off
Saddle tapping valve piercing not
complete or clogged, if applicable
Low water pressure
Incorrect Tubing Connections
Storage tank depleted
Other devices connected to
system demanding too much
water, too many other devices
Lengthy plumbing run, vertical
plumbing, unit in a remote location
Storage tank pressure is wrong
Storage tank valve not opened
“TDS” Creep
See RO Maintenance
Kinked or bent tubing
Saddle tapping valve, if applicable
may be restricting flow or misap-
plied on type of pipe being used
(only applicable on hard pipe of
copper, brass or steel)
Clogged prefilter cartridge and/or
other cartridges
No water
Not enough water
Water flow is restricted
Low flow from unit
•Turn main water supply on
•Saddle tapping valve not open, if applicable
•Turn water on at inlet connection, other if applicable
•Follow instructions to re-do piercing or use the
preferred method to make this connection
•Unit may not operate properly at less than 35 PSI
feed line pressure (max: 65 PSI)
•Follow instructions to connect tubes to proper fittings
•Empty tank needs to fill over several hours
•Close other connected devices and allow tank to
completely fill.
•Maximum limit to storage tank and 2 other devices
•Total length of combined tubing to tank, faucet, and
other devices not to exceed 20 feet. Vertical piping
not applicable. Remote unit location is discouraged.
•Tank needs 5-7psi without water. Too much or too
little and tank will not fill and dispense water properly.
Check tank pressure with (0-20) gauge. Empty tank
than use bicycle or sport ball pump to adjust
•Empty tank completely and allow system to produce
a new tank of water, empty and repeat
Make longer loop with tubing to remove kink or bend
Back the end of the piercing lance out, turning the
handle counter-clockwise. Then re-insert by turning
the handle of the saddle tapping valve clockwise until
it is again firmly seated. This will clear any possible
debris that can block piercing lance and water flow.
If there is flow rate through unit without filters then
there is a need to replace sediment and/or other
filters based on water conditions and usage
