Choosing A Water Softener

Every homeowner and business owner’s situation is unique. You may have a large or small family, be on city water or have your own well, have rusty or smelly water, or simply hard water. Your daily routine also matters — whether you’re home most days, travel often, or have teenagers with fluctuating water use. All of these factors help us determine the perfect water softener for your Southeast Wisconsin needs.

We use a full line of Fleck control valves combined with a wide variety of tank sizes to give you exactly what you need. Capacities are listed in grains, indicating how much hardness a system can handle before regenerating.

Our Twin Tank Demand Regeneration systems are the best choice for the largest residential applications and some small commercial setups, offering the highest efficiency possible and uninterrupted soft water regardless of usage. While these units are higher priced due to their double tanks and advanced controls, they can save significant money in salt and water over their 25-year life expectancy, often costing about half of what some competitors might quote.

Frequently Asked Questions

Yes. Even treated Milwaukee water is typically 8–12 grains hard, which is enough to cause mineral buildup in pipes, fixtures, and appliances over time. This buildup can reduce efficiency, shorten appliance lifespan, and leave spots on dishes or glassware.

Metered softeners track gallons used and regenerate after a set volume, making them efficient for steady water use. Demand softeners regenerate only when needed, adjusting to changing usage patterns, ideal for households with fluctuating schedules or seasonal guests.

We test for water hardness (grains per gallon), iron content, and total dissolved solids (TDS). For a small additional fee, we can also arrange lab testing for contaminants such as lead, nitrates, or bacteria.

Most households need to add salt every 1–2 months, depending on water hardness, usage, and system size. With our salt delivery service, we can deliver and fill your tank for you.

A well-maintained water softener can last 20–30 years. Our systems are built with durable components, and most owners only need 1–2 service calls during the unit’s lifetime.

Ready to Get Started?

Please don’t buy a water softener without calling us for our advice and price. We will gladly help you over the phone. Sometimes, however, looking over the plumbing job and testing the water, if you have your own well, may be necessary. If someone is trying to sell you a water softener for your Waukesha area home at a price higher than the ones listed here, you’re wasting your money. Our softeners will last 20-30 years, have maybe two service calls in that time, and give you great water. That’s what you want from a water softener. Soft Water Inc also provides Waukesha area water softener salt delivery service, even pouring the salt in the tank for you, making water softener ownership truly hassle free.
