membrane is deemed to be ‘expired’ if the overall reduction rate is <85% (as a general rule). To apply this
to the above example, 200 – 85% = 30mg/L. So, if your test reading was approaching 30mg/L or higher, it
would be time to change the membrane.
Troubleshooting
Problem
Possible Cause(s)
Solution
Leaking between
fitting & tubing
Unseated Tube
Check all tubing connections by firmly pushing them into the
fitting. Check that there are no kinks or any obvious issues. If
the problem persists, remove the tubing and check for a clean
cut with no burs. Push the tubing back in and try again. If this
does not work please contact customer support.
Leaking from
Feed Water Valve
1. Damaged or
Missing Washer
2. Not Tight
Enough
3. Thread is too
Short
1. Check the valve to see if the washer is inside, if it is
damaged it may need replacing – this is a common size
washer and can be purchased from most hardware/plumbing
stores.
2. If the diverter valve is loose (or you can easily swivel the
fitting without resistance, the fitting is not tightened enough. It
may feel like you can’t tighten it anymore and it just keeps
spinning but if you use a gripping tool (multi grips) to grab the
collar of the fitting and use your hand to hold the valve itself
steady, you will be able to further tighten the valve. The valve
is tight enough when you feel light to moderate resistance
when trying to swivel the valve.
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. Water Quality
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-filters
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. Low Pressure Reverse Osmosis requires 25psi (Minimum)
to operate – 70psi is ideal. If you have lower than 25psi
pressure this unit may not be suitable for you.
4. Ensure that the water quality meets the feed water
requirements outlined previously. High levels of impurity such
as hardness and salt can cause the system to block or not
produce water.
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 – 1:2 waste
water ratio at 50 psi. If your pressure is lower than 50 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 less 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
(If Applicable)
2. GAC Filter
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.
