About Residential Water Softeners & Conditioners
Sizing a system? Send your flow rate and a feed-water analysis, and an AMPAC engineer will work out the configuration with you.
Need a bulk/commercial system? See our commercial & industrial water softeners page for restaurants, hotels, and factories.
Water softeners remove hardness minerals, calcium and magnesium, by ion exchange, and they're sized in grains per gallon to match your water's hardness (1 grain equals 17.1 ppm). AMPAC USA builds its softeners at its Woods Cross, Utah facility on legendary Clack control valves, sized to your household's usage so the unit regenerates only when needed, which cuts salt use and running cost. Sizing matters: an undersized softener regenerates too often and sends extra salt down the drain. Beyond residential units, AMPAC manufactures commercial and industrial softeners for boilers, cooling towers, hospitals, laundries, food-processing plants, car washes, and apartment buildings. Call (909) 548-4900 to size the right softener for your water.

Frequently Asked Questions
What is the difference between a water softener and a salt-free conditioner?
Water softeners use ion exchange to physically remove calcium and magnesium, replacing them with sodium. Salt-free conditioners change the structure of hardness minerals so they resist scaling but do not remove them. Softeners are best for severe hardness; conditioners suit those avoiding added sodium.
What grain capacity do I need for my home?
Capacity depends on household size and water hardness. A family of four with 15 GPG hardness typically needs a 32,000 to 48,000 grain system. AMPAC USA offers units from 24,000 to 80,000 grains. Larger capacity means longer cycles between regeneration, which saves salt and water.
Will a water softener protect my RO membrane?
Yes. Hard water causes calcium scaling on RO membranes, which reduces flow and shortens membrane life. Installing a softener upstream of your RO system is one of the most effective ways to extend membrane replacement intervals and maintain stable TDS rejection.
How often does a water softener need to regenerate?
Metered systems regenerate based on actual water use, typically every 7 to 14 days for an average household. Timed units regenerate on a fixed schedule regardless of consumption. Metered regeneration uses less salt and water overall, making it the more efficient choice for most homes.
Can I install a water softener myself?
Basic installation is manageable for a confident DIYer with plumbing experience. You need a bypass valve, drain line, and access to an electrical outlet for the control head. Most AMPAC USA softeners include installation instructions. Complex setups, such as homes on a well, may benefit from professional installation.
