Standard water filter replacement instructions

Close the ball valve on the reverse osmosis tank. This is usually done by turning the blue ball valve on the top of the tank one turn clockwise.Step 3. If you have a line to your refrigerator or ice maker from your RO system, turn off the ball valve on the line leading to your ice machine.Step 4. Open the RO faucet and allow the pressure in the system to drain.Step 5. Place a shallow tray or pan under the filter housing to catch water that may spill during filter change.Step 6. Remove the vertical filter housing from the cover and remove the used filter cartridge. If you have trouble removing the filter housing, a special wrench for the filter may be needed.Step 7. Carefully remove the O-rings and place them on a clean surface. Wipe the O-rings with a clean soft cloth and visually inspect for cuts or abrasions that could cause the O-rings to misplace in the filter housing. If the O-ring is damaged, replace the O-ring.Step 8. Rinse the disconnected filter housing with warm water and a small amount of liquid soap. Make sure all soap is thoroughly drained from the filter housing before inserting a new filter and reinstalling it.Step 9. Lightly lubricate the O-ring with a silicone lubricant. Insert the O-ring into the O-ring groove of the filter housing. It is important to make sure the O-ring is properly seated in the groove as it creates a watertight seal between the filter housing and the filter cover.Step 10. Measure the new filter to make sure it is the correct length. Remove the new filter from the plastic or paper packaging.Step 11.

Instructions for replacing reverse osmosis MEMBRANE

The standard reverse osmosis system has a horizontal membrane above the holder that holds 2-3 vertical filters.generic-ro-membrane.jpgStep 1. Follow steps 1-5 above, if you have not already done so. Read more: How to clean Plastic BubblesStep 2. Disconnect the tube from the membrane housing cap (usually on the right side of the housing) by pressing down on the small ring where the tube connects to the cap. Press and hold the ring while you pull the tube out.Step 3. Unscrew the membrane housing cap from the membrane housing and remove the RO membrane. The membrane usually stays there for 1-3 years and can be difficult to pull off. This may require needle nose pliers for removal.Step 4. If you want to clean the membrane housing, disconnect the two tubes at opposite ends of the cap. Label each tube so you can rejoin each tube later in the correct position. Usually there are two clamps that hold the membrane cover in place. Remove the membrane cover from the clips and wash the inside of the membrane cover with warm soapy water. Ensure that all remaining soap is rinsed off.Step 5. Insert the new membrane into the case with the front o-ring tip and the large outer rubber stopper closest to the cap open. Push the membrane in until you feel the o-ring seat firmly adhere to the membrane housing. You may need to move the membrane in a slight circular motion to center the membrane and apply a good amount of pressure to ensure the membrane is fully seated. If the membrane is not in place, untreated water will flow unrestrictedly through the system.Step 6. Replace and tighten the membrane housing cover. Reattach the removed piping to the appropriate fittings. To ensure that the hose is properly fixed, push the hose into the appropriate fitting as far as possible, then gently pull the hose to lock it in place.Step 7. If you removed the tube at the opposite end of the membrane housing cap, reassemble each tube in place and secure it by following the instructions in step 6.Step 8. If your system has a horizontal inline filter on top of or next to the RO membrane you are replacing, follow the “Following Inline Filter Replacement Instructions” below. Otherwise, go back to Step 12 in the “Standard Filter Replacement Guide” to complete the installation.

Follow steps 1-5 above, if you haven’t already done so.Step 2. Disconnect the hose from each end of the filter, or from the coupler connected to each end of the filter, by pressing down on the small ring where the hose connects to the filter or fitting. Press and hold the ring while you wiggle and pull the tube out.Step 3. If your filter has separate fittings screwed onto each end of the filter, remove the fittings from the old filter after disconnecting the hose. Use plumber’s tape to wrap the thread end of each connector 2-3 times. Screw the threaded fittings onto the new filter.Step 4. Connect the hose to the filter by pushing the hose into the fitting or filter at each end as far as possible. Then, gently pull on the pipe to make sure it is securely locked in place. (If a leak occurs from these connections after turning on the feed water, that usually means the pipe is not pushed far enough.)Step 5.
