How to Change the Reverse Osmosis Membrane
1. The RO membrane typically lasts about 2 – 3 years. The membrane life span depends on the
source water quality, your water usage, and how often the three pre-filters are replaced. To
ensure the system's performance and water purity, it is important to replace the pre-filter
cartridges on schedule. Use a TDS meter to periodically check the RO water purity.
2. Shut off the cold water supply valve and tank valve, and open the RO faucet to depressurize
the system. Place a bucket or towel under the system to catch any water spills.
3. Remove the tubing from the quick-connect fitting on the membrane housing cap. Use the
membrane housing wrench to twist off the housing cap in a counter-clockwise direction.
4. Pull out the old membrane. Use scissors or pliers to apply leverage if necessary.
5. Clean the membrane housing using hot water and scent-free dish soap (optional). Rinse
thoroughly.
6. Cut open the small end of the vacuum sealed packaging containing the new RO membrane.
Hold the new membrane through the packaging, and insert it into the housing without
touching the membrane with your bare hands to avoid contamination of the membrane.
Make sure the O-ring is properly seated on the end of the membrane housing as shown in
7.
the previous images. We recommend replacing the O-ring every 3 years to prevent leaking
due to an expired or dried out O-ring.
Place the membrane housing cap back on and hand tighten it, then use the housing wrench
8.
to tighten it another ¼-½" of a turn. Do not over tighten.
Stage 5 FT15 Inline Post Carbon Filter and Stage 6 FA15 Inline Alkaline Filter
Replace the FT15 every 12 months and the Alkaline filter every 6 months
1. Remove all quick-connect tubing connections from the FT15 Post Carbon Filter.
2. Unscrew the fittings from both ends of the old Post Carbon Filter. Wrap the thread of each fitting 2-3
times with Teflon tape, and screw them into their respective sides on the new Post Carbon Filter.
3. Reconnect the quick connect tubing connections to the new Post Carbon Filter.
Tank Maintenance
It is recommended to fully empty and refill the tank at least once a month. This keeps the water
inside the tank fresh and not sitting for an extended period of time.
What should I do with the system when going out of town?
When you are leaving for an extended period of time, you will want to shut off the water supply to
the system and empty the tank. To do this, close the knob on the feed water adapter, and open the
faucet until it stops running. This will signify that the tank is empty. The filters should be replaced
if the system is not used for over a week as they will be sitting in stagnant water.
