How to Change the RO Membrane
(Recommended about once a year)
NOTE! Make sure water flow to the system is off
1. Remove the 3 stem elbows attached to the Reverse
Osmosis Membrane Housing. For detailed directions of
disconnecting these refer to the Quick Connect Guide
(Page 12)
2. Unscrew the cap from the Membrane Housing and remove the Membrane inside, be sure to note the
correct orientation of the membrane
3. Wash out the RO Membrane Housing
Mix ½ gallon of water with 1 tbsp of household bleach
Note: Do not add bleach directly to the membrane housing
Scrub the inside of the membrane housing with the bleach mixture
Rinse the housing until all traces of bleach are gone as bleach will damage your membrane
4. Install the new RO Membrane in the Housing in the correct direction you noted earlier (the single large
rubber ring will face towards the cap). Make sure to push the Membrane in firmly and check to see if the
o-ring is in place. Then close the Housing by tightening the cap with your hand.
5. Now reattach the stem elbows to the RO Membrane Housing. If this is the only/last filter you are changing
begin the “System Startup” instructions on Page 14.
Make sure the O-Ring is in place

Filter and RO Membrane Storage
- Store unopened filters in an airtight container to prevent them from absorbing air. This prolongs the shelf
life of the filters and avoids any possible odors or contamination from the air.
- Using this method it is okay to store filters for several years. Store in a cool, dry, dark place (avoid heat and
moisture contamination).
Troubleshooting
FAQ’s
Does this system filter Fluoride, Lead, Pharmaceuticals, and Arsenic?
Yes, as well as Cyanide, Phosphate, Pesticides, Sodium, Cadmium, Sulfates, and many other contaminants
up to certain levels. You may need other changes to media for high levels of these substances.
What PSI do I need? What is the operating pressure?
The minimum PSI for the system is 45 and the maximum PSI is 80. If your PSI is too high you can purchase
a Pressure Regulator to reduce your pressure to acceptable levels. Let us walk you through these options;

Does this unit soften water?
Your RO System will soften water. However, hard water does reduce the lifespan of your filters.
What is the discharge rate?
The typical discharge range is one to three gallons for every one gallon produced. Your water pressure,
incoming water quality, and water temperature will affect your RO System’s discharge rate.
How often do I change Filters? Is there an indicator?
The Sediment, GAC, and PAC Filters should be changed every 6 months. The RO Membrane should be
changed every one year at the same time as the second change of the 6 month filters. There is no direct
indicator for filter changes. However, if you notice a drop in water quality before the 6 months or 1 year
mark this may mean that due to your water quality your filter has degraded. If you reach 6 months or 1
year without noticing a change in taste you should still change your filter at this point as they are no longer
viable.
Can I add additional filters to my current system?
Yes, each system is fully upgradeable. Check the Upgrades and Accessories section at ExpressWater.com
for more information.
Can I reuse discharge water?
Never consume discharge water. With proper installation it is possible to utilize your discharge water.
Contact Express Water to speak with a qualified representative who can give you more information based
on your situation.
How long does the system last?
With proper maintenance and average water quality an RO System should last 5-10 years.
Does this produce aquarium safe water?
While the water is perfectly safe for human consumption, we suggest installing our Deionization Filter
Upgrade to create water for aquatic life.
Why do I need to flush the system?
New filters (or filters that have experienced extended disuse) can develop carbon residue. Two hours of
constant flow is recommended to release any extra carbon before the water is safe to drink.
