All Whirlpool® Water Softeners use Demand Initiated Regeneration with Salt Saving Technology so the system only recharges when necessary, saving salt and water. This eliminates the need for a manual regeneration of your water softener. Instead of calculating how often your water softener should regenerate, you can set it and forget, enjoying predictably soft water on a daily basis.

During the softening cycle, sodium on the resin beads is exchanged for hard water minerals in the water. After some time, the resin beads need to be rinsed free of the minerals and “recharged” so they can continue attracting and collecting hard water minerals.

Hard water can be tough on your home, your skin and your wallet. Water softeners counteract those effects, by creating better quality water that extends the life of your appliances while also helping you and your home look and feel better.

This 1 inch lead free brass water pressure reducing valve is the standard model, designed to reduce incoming water pressure to protect plumbing systems and reduce water consumption for commercial, industrial and residential applications. The easy maintenance assembly consists of a replaceable seat module, NPT threaded female union inlet by NPT female outlet and a bypass feature to control thermal expansion pressure. The temperature range is 33 to 160 degrees F (0.5 to 71 degrees C). Suitable for up to 300 psi (20.7 bar), the pressure range can be adjusted from 25 to 75 psi (172 to 517 kPa) with the standard setting at 50 psi (345 kPa).

One of the biggest misconceptions about water softeners is that the salt is what softens your water. What actually softens the water are thousands of tiny resin beads within the tank that filter out hard water chemicals. The salt is used to clean the resin beads during a regeneration cycle, allowing the system to continually remove hardness from your water supply.

Water softener regeneration cycle time is about two hours. It is not recommended to use water during a water softener regeneration, as hard water will fill the water heater, which could lead to buildup in the equipment.
