3. If you screw the valve on and
the collar ‘bottom’s out’ on the
tap, you may need to add
another washer (to bulk up the
space).
The unit is not producing any
water?
1. Water Supply is off or
disconnected.
2. Pre-Filter has a blockage
3. Insufficient Water Pressure
4. Blue Plug Still Installed
1. Turn on the water supply and
ensure there are no obstructions
to the water flow.
2. Disconnect the tube between
the membrane and pre-filter (like
the pre-flushing instructions) and
run water at full pressure to see if
water comes out of the filter. – If
the water does not come out (or
is very weak pressure) the filter
may need to be changed.
3. Reverse Osmosis required
50psi (Minimum) to operate –
70psi+ is ideal. If you have lower
than 50psi pressure this unit may
not be suitable for you. Low
Pressure Membranes are
available for an additional charge
that will work down to 20psi.
4. Remove the blue plug from the
drinking water line.
Water is coming out slowly
Reverse Osmosis
RO filtration is a slow process,
depending on the system you
have purchased, you will only get
about 8 – 12L of water per hour.
I am getting much more waste
water than filtered water
1. Water Pressure
2. Water Quality
3. Blockage
1. Our units are designed to run
at approx. 1:1 – 1:1.5 waste
water ratio at 70 psi. If your
pressure is lower than 70 psi, the
production rate may decrease
and cause more drain water than
filtered water.
2. If your inlet water quality is
poor and contains higher salts
and hardness the filter may
produce lest water than the
specified amount.
3. If you have good pressure,
and average water quality it is
possible there is a small
blockage somewhere in the
system. Try to follow the water
flow along the system,
disconnecting 1 tube at a time to
try and pinpoint where the water
is ‘stopping’
High pH Reading
1. Insufficient Testing Equipment
2. Wrong Configuration
1. pH testing equipment can
range from a cheap test pen right
up to lab grade equipment.
Before coming to a conclusion on
pH issues, it is best to ensure the
equipment used to measure the
pH of the RO water is of high
standards and suitable for
reading pH levels in low EC
