| There are only four
possible causes:
1)
ASOV (inlet side and back side)
2)
Filters
3)
Plumbing problem –connection-( If
this is a new install this is your first step)
4)
Membrane
Low production is caused
by low water pressure at the membrane.
Locate the membrane vessel
(large horizontal filter on the upper portion of the unit.)
The membrane vessel has
three connections, two at one end and only one at the other end.
The single connection is
the one you want. That single connection is the membrane feed tube. What you
want to find out is how much water is reaching this point.
Turn the water supply to
the unit off. Carefully disconnect the membrane feed tube. Now, prepare for a
blast of water. Aim this tube at a bucket. Turn the water supply back on; you
should have a torrent of water blasting into the bucket.
You probably did not
experience this. Why?
Could be a problem or
defect in:
1) The ASOV
2) The carbon pre-filters
3) Your connection
1) The ASOV automatic shut
off valve. To test this valve reassemble the membrane feed tube, now follow the
tube back to the ASOV. Directly across from it on the other side is the inlet
from the filters. Following the same procedure as before, test the water supply
here at the inlet of the ASOV.
Did you have good
pressure? If yes then your ASOV is bad. For our customers we will send a new one
out no charge.
No, I did not have a good
flow- see 2
2) Dirty or clogged
filters will not allow enough water to be filtered. Have you changed your
filters?
On rare occasion a new one
micron filter is defective and does not allow enough water to be filtered.
You can shut down the
water supply to the system, wait for the system to de pressurize.
Remove the carbon filter
from the filter housing and replace the housing empty.
Restart the system. Wait
for at least 20 minutes and check your output.
*On chlorinated water
never run your system without at least one carbon filter in place.
Did this help? You can
repeat the process with the other filter but it may not be the problem.
See 3
3) For new systems or
systems on very poor quality water. Your connection may not be good or may be
clogged. Turn off the supply water; wait for the system to de-pressurize.
Disconnect the inlet tube (your water in). Aim it at a bucket turn the water on.
You should have a major blast of water. If not you did not pierce the supply
needle far enough when you pierced the home supply tube. Please go back to the
supply valve and close it. Snug the valve a little more than it is now. That
will push the needle to enlarge the hole. Now reopen the valve and test system
after about ten to fifteen minutes.
4) It is not typical for a
membrane to suddenly decrease production. It is usually a slow loss of
production. However if everything else checks out and you have a good water flow
up to the membrane, it may be time for a new membrane.
Membranes are rated at 77
degrees temperature and 50 PSI.
For every pound of
pressure less than 50 subtract 2% of the output. Example 40 PSI subtract 20% of
the 75 for 60GPD
For every degree below
(77) you lose production. Subtract 1.4% per degree lower than 77. Example 57
degree water is 20 degrees less than optimum. 20 x 1.25 = 25% less production.
So a fifty GPD membrane will only produce 75% or about 37 gallons
Please remember:
Combine the pressure and
temperature answers together and subtract them from your membrane rating. Your
membrane should produce water at or very near that answer
