RO Membranes have a life expectancy between 2 and 5 years, depending on the incoming water
conditions and the amount the RO system is used. This reverse osmosis membrane is critical for
effective reduction of total dissolved solids (TDS). The product water should be tested periodically to
verify that the system is performing satisfactorily.
Normally, a membrane would be replaced during a semiannual or annual lter change. However, if at
any time you notice a reduction in water production or an unpleasant taste in the reverse osmosis
water, it could be time to replace the membrane. Watts Premier recommends replacing the
membrane when TDS reduction falls below 75%.
A water sample may be sent to Watts Premier for a free diagnosis of your membrane
performance.Tosendawatersample,usetwo(2)cleancontainersandll½cupoftapwaterin

Send the samples to the address listed on the cover of this manual attention “Water Samples”.
Watts Premier will test the water and mail or call you with the results.
Your reverse osmosis system contains replaceable treatment components that are critical for effective
contaminant reduction. Periodic inspection and following proper system maintenance is critical for
continued performance.

Membrane Maintenance
Use a 5/8” wrench to remove the Green Tube tting on the left side
of the horizontal membrane housing (end with one elbow).

Note:
Step 1
Turn off the incoming cold water supply to the RO at the adapt-a-
valves and unplug the power transformer..
Open the RO Faucet and allow water to drain from the tank until it
is completely empty.
Step 2
Removing the membrane:
Installing the membrane:
Follow the Start Up Instructions on page 8.
Remove the cap from the membrane housing by turning it counter
clockwise to loosen.
A double sided wrench may be purchased from Premier to aid with
loosening the cap / lter housings. (Part # 164003)
Remove membrane housing from the holding clips. Using a pair of
pliers, grip the PVC tube of the RO membrane and pull rmly on the
membrane to remove from the housing and discard.
Lubricate the O-rings on the new membrane with a water soluble
lubricant such as KY Jelly ®. Insert the end with the two black
O-rings rst into the housing.
Once membrane has been inserted into the housing you must take
your thumbs and give a rm push to properly seat the membrane.
Replace membrane housing cap and tighten.
After replacing membrane housing into clips, attach the green tube
to the elbow on cap using 5/8” wrench.
