Steps with Instructions To Install A Reverse Osmosis System

The following are the steps to install a reverse osmosis filtration system without calling out to a plumber.

1. Planning 

You need to plan before buying a reverse osmosis system. There should be enough space under the sink cabinet so that the system can be installed with a perfect fit.

Take proper measurements. If you have already installed a garbage disposal unit or any other unit underneath the sink cabinet, the RO filter will be a hard fit. 

2. Preparing

So, now when you have brought your RO system home, double-check to be sure of all the components.

The fitting components should be of the right size according to the measurements you took for your desired location.

If you have chosen a remote location, be prepared to work a little harder and extra because it will take time to connect the tubing with the filter and then with the cold water line. 

3. Install The Sink-Top Spigot

The first step is to install the sink-top spigot so that the lines down the sink are all sorted out before it gets too messy with the other lines and pipes coming through the filter.

Many sinks have a knockout opening that doesn’t demand any effort. Mount the spigot to the kitchen sink deck. Now, attach the waterline to the opening of the sink and connect the red tube into the faucet. 

4. Tank Positioning

First, install the tank connector and apply plumber’s tape on the top threads of the tank’s opening.

Screw the spigot connector with the tank. Tighten the connector with your hand and place the tank under than sink.

Remember! Avoid cross-threading so that nothing will get mingled up.

5. Filter Assembly Mounting

Mark the location for the hanger washers and remove the filter assembly to set them up on the wall below the sink.

Do a recheck before placing the filter assembly that it is at a minimum distance of 15 1/2 inches from the floor. Screw the hangers tightly on the marked place and place the assembly mount on the washers.

6. Attach The Water Line

Connect the ¼ inch green water line to the water supply line. Turn off the water supply.

You will need to use an adapter tee if the faucet uses a different flex tube than the standard one. It will make the transition to the water supply tube easier. 

7. Connect The Tubing

The tubing connection usually depends on how the manufacturer has designed the RO system. In a typical connection, a tube runs from the water supply to the first canister that is the pre-filter.

The pre-filter further connects to another tube from the last canister that is the RO canister to the sink and then another one to the tank.

8. Connect The Drain

Place the filter’s tee fitting against the drain pipe and cut it using a hacksaw. Fit the drainpipe with the filter’s pipe and connect the drain trap with the help of nuts and washers.

9. Pressure testing

Finally, perform a pressure test. Turn on the cold water supply so that you can feel the water coming out of the faucets with pressure.

Extra Tip! Check all the gauges and pipes for any leakage so that you can rest assured about the fittings.
