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. Alkaline Filter
2. GAC Filter
3. Insufficient Testing Equipment
1. Alkaline Filters are designed to
increase the pH of the water.
When the filter is new it will be
high but will soon settle to the
advertised levels after adequate
flushing.
2. If you have a post GAC filter
(Carbon), this will naturally
increase the pH of the water. pH
is the measure of Hydrogen in
the water and this hydrogen will
vent off the water if you leave it
to stand and the pH will then
drop back down to the normal
level.
3. 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
water (i.e. The guy at the pool
