If you want to add a water softener system to your kitchen plumbing, there are a few things to keep in mind before deciding to install it yourself or have it done by a professional. The softener systems referred to here are not the type installed on a kitchen sink faucet, but connected to your plumbing system. Water softeners are installed on the main water supply line, so the entire water supply to your home is treated. The only faucet not affected by the softener system is your outdoor faucet used to run a garden hose or sprinkler system.
Most building codes require installation of a bypass valve so that your faucets can dispense non-treated water if a problem develops with the water softener system. Your kitchen faucets will dispense non-treated water only when the bypass is activated. Some people prefer a bypass line that supplies drinking water or a connection to a refrigerator ice machine.
One important consideration when installing a water softener is where to store the softener unit. Some prefer installing the softener equipment in the garage, while others use the laundry room. Wherever you store the unit, you will need the right length pipe or tubing to connect the unit to your plumbing system.
