How to install a water softener
A new water softener is typically installed in a basement or utility room near the water heater. This is usually where tying into the plumbing system is easiest and floor drains or utility sinks are present. Also, an electrical receptacle capable of handling the unit’s amperage should be nearby.
How to install a water softener
Position the unit where it will be installed so you can easily measure for connecting pipes. Turn off the water at the water heater. Close the main water supply valves and drain all water from the pipes. Most softeners come with a bypass valve that must be assembled and attached to the unit, and many local plumbing codes require installation of shutoff valves to the pipes that lead to and from this valve.
With these valves assembled and connected to the softener per manufacturer instructions, you can then cut into the home’s water supply line and install elbow fittings that allow you to run two lines – to the inlet and outlet ports of the bypass valve. Hard water from the supply runs into the softener’s inlet, and soft water runs out from the outlet to the home’s faucets and fixtures.
If you want to keep a hose bib supplied with hard water, install a Tee-fitting before the softener and run it to the outlet so the soft water isn’t being used to water lawns or wash cars.
This water softener contains both the brine tank and mineral tank within one housing. Plumbing connections to the blending valve are made behind the unit. Note the presence of the mesh filter mounted to the wall, which aids in removing dissolved iron from the water supply.
Cut, install and solder all pipes and fittings before attaching them to the bypass valve, which will often have plastic components that can be damaged by heat. Attachments to the bypass valve are usually done with compression fittings.
Clamp the drain hose to the softener and run it to a drain or utility sink. The end of the drain hose should be at least 2 inches above a drain hole and securely clamped. Connect the brine tank’s overflow tube and follow manufacturer instructions for any other additional assembly.
Set the bypass valve to “Bypass,” turn on the water and flush the system for a few minutes to flush out sediment and expel air in the pipes. Set the valve to the “Service” position, plug in the unit’s power cord and fill the tank with water and salt per manufacturer instructions.
