Connect The Drain Tubes

Two drain tubes are required by most water softeners. The control valve is connected to the drain tube of the washing machine. The other drain tube is connected to the brine tank.

You may connect the drain directly to the home drain system. But it must have an air gap. 

It prevents contaminated drain water from flowing back into the water softener. There are some special air gap fittings. These allow connecting the drain tubes of the water softener to sewage directly.

Now, connect the water softener on the control valve and brine tank with flexible tubing. A 1/2-inch length of flexible tubing is recommended. 

Make sure to check the valve if it has any air admittance issues.

Using hose clamps, direct the tubes to the washing machine’s drain. If you’re using one, secure them to an air gap fitting.

The tube could connect to a drain pipe that has already been plumbed. As a result, press the tube’s end over the drain pipe’s fitting. Carry on until the pipe fitting’s ribs are passed. Don’t forget to use piping support.

The pipe support bears the pipe’s and its contents’ weight. It ensures the integrity of the pipe system. That is why it is critical to be aware of it.

Now, pipe hangers are used to secure the drain tube of the water softener. For every 2 to 4 feet, fasten the pipe hangers to the wall or floor.

A pilot hole must be bored in concrete or tile floors, and a concrete screw must be placed. Concrete screws are sold in kits that include a drill bit of the right size. Now, drill a pilot hole. Use an electric drill for it. Finally, your installation is ready!
