A water softener bypass valve is used to regulate the needs of the water softener. The homeowner can easily bypass the softener altogether if they do not need it for specific uses. Installation of the water softener bypass valve is a simple process.

Before you cut any pipes along the water line you must first assemble the bypass valve according to the manufacturer's directions.

Step 1 - Cut Water Line

Determine where the water softener bypass valve will be placed and cut the water line with the pipe cutters. Run some emery paper over the edges to remove any burrs.

Step 2 - Apply Flux to Pipe

Once you have sanded the edges of the pipes, apply some flux to both the pipe and the bypass valve.

Step 3 - Assemble Valve to Pipe

Run the pipe into the bypass valve. Once it is pushed as far as it will go, turn on the torch and heat the intersection.

Step 4 - Solder the Pipe

As the pipe heats, you can touch the pipe with the solder. The solder will then melt around the pipe and form a watertight seal between the bypass valve and the pipe.
