AWS Series Water Softeners
Meets California efficiency rating (4,000 grains/lb of salt)
Fully automatic from start to finish, these highly efficient water softeners reduce unsightly soap curd, spotted glasses, and rings on tubs and sinks. Soft water washes away soap that hard water would leave behind, allowing your natural body oils to surface and moisturize your skin, reducing the need for costly lotions.

An electronic metered valve monitors water use and activates the regeneration cycle of the water softener only when needed based on your water consumption, saving you money on water and softener salt. High capacity resin comes standard with these water softeners requiring less salt and rinse water needed for regeneration than standard resin. Just one of the reasons they meet the California salt efficiency rating of at least 4000 grains per pound of salt used for regeneration.

For best water softener results, we suggest a water filter be installed before the inlet of any water softener to keep sediment from interfering with the internal parts of the control valve. A 20 or 30 micron water filter will adequately remove particles that could harm your water softener equipment. We offer Jumbo, large capacity, filter housings and filters to fit any water softener with 1", 1 1/4" or 1 1/2" piping inlets.

For those that live in the State of California and who plan on installing a water softener in California, California Assembly Bill 334 could affect restrictions on any brand of residential water softening. This passed bill has been the subject of much controversy in California. It is our understanding that it authorizes local California agencies to regulate the use and availability of self-regenerative water softening appliances that discharge to the community sewer system, effective January 1, 2004. Please be aware of the laws in California. It is up to you who buy and install a water softener destined for California, to check with your local authorities to see if water softeners (all brands, certified or not) are legal in your area. Crazy but true: just because these great softeners have been certified for the State of California, it still does not mean they may legally be installed in your area.
It is our understanding that in February 2003, the Los Angeles County Sanitation District, in conjunction with the Santa Clarita City Council, voted to ban installation of regular ("self-generating") water softeners. The area affected has been estimated to affect about 250,000 people. We have been told that they took this action because that Sanitation District was in violation of chloride wastewater standards of 100 mg/L.

Frequently Asked Questions

Q. "What is the difference between "Timed Clock" and "Mechanical Metered?"
A. Timed clock is manually adjustable. When you install your unit you can set how many days until regeneration. For example: every 3 days at 2:00am. Mechanical Metered automatically regenerates depending on your amount of water usage.

Q. "How does regenerating a water softener with salt make the water soft?"
A. During the normal "in service" or conditioned water position of the valve, hard water enters the resin tank through an inlet in the valve at the top of the tank. The resin tank is filled with cation resin beads that have sodium or potassium ions attached to them. As hard water comes in contact with the resin beads, the hardness molecules or ions, such as magnesium and calcium, attach and stay on the resin molecules and at the same time release the sodium or potassium molecules. If sodium chloride (NaCl) is being used as the regenerate material then sodium ions are released. If potassium chloride (KCl) is being used, the potassium ions are released. This is why it is called an ion exchange. The result is the quality and convenience of soft conditioned water. After a period of use, the sodium or potassium ions are depleted until only hard mineral ions are left on the resin beads in the tank and the water can no longer be softened and needs to be regenerated. During the regeneration cycle, the system washes the resin beads with sodium chloride or potassium chloride, whichever is being used. This regeneration washing overpowers and forcibly removes the hardness and scale molecules off of the resin beads, replacing them again with the sodium chloride or potassium chloride molecules. Please note that only the sodium or potassium is released into the conditioned soft water. The chloride portion of the molecule stays attached to the resin and any excess is pushed out the drain along with the hardness and scale molecules during the regeneration cycle.

Q. "I recently had a water softener installed and the water now feels very different. Can the water be too soft?"
A. Water cannot be too soft. The feel of the higher quality water should be more slippery as the soap glides off your skin instead of plugging your pores.

Q. "The location I would like to install this water softener does not have power. Do these softeners need power to operate?"
A. Yes these units require power. Electrical requirements are: 110/120v, 60Hz.

Q. "During the regeneration process of a water softener is it ok to turn on the faucets, take a shower, etc? Will it mess up the regeneration process?"
A. Running water while the softener is regenerating will not mess up the regeneration process, but any water used during the regeneration cycle will not be softened. If water is used while the water softener regenerates, water that would normally go through the softener now automatically bypasses the softener and runs straight to the fixture being used and to the water heater if any hot water is being used.
