Reverse Osmosis is the process where high-pressure is used to filter water. It has been used for many years to change salty water to drinking water. This process removes as much as 99% of impurities from the water, ensuring you of having clean and safe water coming from your faucet.
Installing the reverse osmosis system may seem difficult because of the number of filters, several colored tubes, and parts, but it is actually very easy. Following are the step-to-step guide to install a reverse osmosis system.
Prepare the required tools. This includes the following:
- 3/8- and ¼-inch drill bits
- Faucet drill bit
- Phillips screwdriver
- Tubing cutter
- Channel lock pliers
- Adjustable wrench
- Teflon tape
- Utility knife
- Take your reverse osmosis system out from the box.
- Check if the box contains all the parts listed in the product manual.
- Check the space under your sink. Clear the space to ensure that you have enough space to work and to place the tank. Put a cover on the bottom of the sink cabinet to avoid moisture from ruining your reverse osmosis system.
- Install the water supply feed of the RO system. You can mount it on either side of your sink. Make sure there is sufficient empty space or allowance on the underside of the sink.
- Drill a hole and drive the plastic supply tube on the inlet valve. Fasten the nut at 180-degree turn using your hand, making sure it is tightly secured.
- Attach the filter assembly on the side or back wall of your sink base or under the sink, following the height specified in the instruction manual.
- Shut off both the hot and cold water valve then install the saddle valve that comes with the RO system
- Cut the color-coded water supply tube so it is on top of the cabinet base to prevent it from getting twisted. Attach the plastic tubing to the supply valve.
- Clip the water supply and waste lines to the faucet to remove extra tubing. Be careful not to clip the larger black waste line, though.
- Fasten the lines to the fittings on the base of your faucet. Insert the black waste line through the base of your faucet.
- Attach the faucet to the sink then mount the drain line adapter under your sink basket. Clip the waste line so it glides downward without any knots. Shove it into the adapter.
- Set the water storage tank and mount the last water line. Read the manufacturer’s manual on how to fix the tee fittings or elbow on the reverse osmosis system and the tank. Select where you want to install the assembled filters and the water storage tank. The filters are usually installed on the side of the cabinet, as this makes it accessible. When you have positioned the storage tank and filters, connect the lines as per the product manual.
- Check the empty pressure of the tank. Loosen the protective cap and check the pressure of the tank. Using a tire pump, inflate or deflate it according to the recommended pressure of the manufacturer, which is normally 5 – 7 psi.
- Check if you have installed the RO system correctly. Slowly switch on the cold water supply valve so the filters can get filled with water. Turn the tap on halfway only. Check for any leaks once the filters are getting filled up with water. If you notice any leaks, close the water supply and reset the leaking lines. Check once again to see if there are still any leaks.
- Switch off the RO system faucet once the filters are filled with water. There is usually a sound when these are filled (the manual may describe the kind of sound they produce). Wait for the water storage tank to get filled up with water. Do not use this water but instead, flush the water out from the tank. This is because the water is still not clean, containing contaminants and unwanted elements that are in the storage tank and filters.
- When you have set up everything, check the connections and ensure that every part is well fastened and secured.
