4.
Systems with UV
Check flow coming out of the UV filter, if
flow is reduced there is an obstruction in the UV housing.
Unplug the UV before checking for obstructions
5.
Remove the waste water (yellow) line from the membrane
housing (a capillary flow restrictor is installed in the line) and
check water flow; there should be a steady flow of water. If
there is no water flow and water is reaching the membrane,
the membrane is fouled and needs replaced.
6.
Check flow after the flow restrictor. Flow should be reduced,
but should still be coming out in a steady stream. If flow is the
same or if flow is completely gone, the flow restrictor is
defective and needs to be replaced.
7.
Check the line coming from the check valve on the membrane
to the auto shut off valve (refer to the connection diagram if
you are unsure where the check valve is). You should get a
steady drip or a slow stream. If there is no flow, remove the
check valve (simply unscrew counterclockwise) and test again.
If flow is achieved by removing the check valve, replace the
defective check valve. If removing the check valve does not
solve the problem, either your pressure is too low (common on
new installations, 40psi minimum is required) or the
membrane is fouled (more common on older systems).
8.
Check line connecting the auto shut off to the T-fitting on the
next filter (refer to connection diagram if you are unsure which
filter is next). Flow should be the same here as it was coming
out of the membrane. If not, the auto shut off valve is stuck
and not allowing water through, replace the auto shut off
valve.
9.
Ensure tank ball valve closed and check the flow of water after
each of the inline filters. (Inline filters may include post filter,
pH filter, and alkaline filter, depending on your system.)
Remove the line after each filter and check the water flow.
Flow should be close to the same through each filter as it was
coming from the auto shut off valve. If significantly reduced
flow is found after one of the filters, replace the filter.
10.
Remove the line connected to the faucet (blue) and check flow
there. If flow is restricted, replace the tubing between the
final filter on the system and the faucet. If flow through the
line is fine but there is no water from the faucet, replace the
faucet.
