Is a softener worth it in Las Vegas?

• The water is hard. LVVWD puts valley water at 280 ppm, or 16 grains per gallon, and says to set your softener to that. Henderson's 2024 report also said 16 grains and suggested a setting of 16 to 19.
• It's not a health issue. The Southern Nevada Water Authority told the Review-Journal hard water has no health impact and is more a matter of preference, and it doesn't necessarily encourage softeners.
• Scale is the real cost. In a Battelle study for the Water Quality Association, water heaters on hard water lost efficiency and built up scale, while heaters on softened water built up almost no scale. More on water heaters
• The trade-offs. The water authority says softeners can raise the sodium in your drinking water, and the salty water can harm plants and septic systems.

Permits and soft water loops

• Permit: the City of Las Vegas says installing or replacing a water softener needs a permit. Installing a water filter doesn't.
• No softener ban: we didn't find any Southern Nevada rule restricting salt-based softeners.
• Soft water loops: some new Las Vegas homes come pre-plumbed for a softener. Lennar and D.R. Horton list a "soft water loop" as a standard feature in some local communities.

Watch for pushy in-home sales

Water treatment is often sold door to door. In 2024 the FTC sued Aqua Finance over dealers who went door to door deceiving people about financing for water softening and filtering systems. The settlement included $20 million in refunds. LVVWD has also warned about people trying to get into homes for fake water surveys, and says its employees never collect payment at your home.

Before you sign: get the system's price in writing apart from any financing, get two or three quotes, and check the installer's Nevada license. You already know your hardness: 16 grains, from the water district's own report.
