Your water softener works hard. Here's how to keep it running smoothly. 🔧

Cleaning your Kinetico brine tank takes about 20 minutes and helps maintain peak performance. We recommend doing this once a year.

Quick steps:

1️⃣ Bypass the softener & disconnect the brine line
2️⃣ Remove remaining salt and water
3️⃣ Scrub the interior with soapy water
4️⃣ Rinse thoroughly, reassemble, and refill

That "rotten egg" smell in your water? It's sulfur, and it doesn't have to be part of your morning routine. 🥚🚫

The Kinetico Sulfur Guard™ works to help eliminate hydrogen sulfide odor without the hassle of multi-stage systems, chemical treatments, or constant maintenance.

Just cleaner, odor-free water. Simple as that.

Common in well water throughout the South Bay, if this sounds familiar, let's test your water (free).

✓ Lead & heavy metals
✓ Chlorine & chloramines
✓ PFAS (forever chemicals)
✓ Nitrates, arsenic & more

If you've ever wondered whether your water is truly clean, this guide breaks it all down, no jargon, just clarity.

Living in Santa Clara? Your water is probably harder than you think. 🏠💧

Santa Clara's municipal water contains elevated levels of calcium and magnesium, the minerals that cause hard water. Here's what that means for your home:

The problems:

• Scale buildup inside pipes, water heaters, and appliances
• Soap that won't lather properly
• Dry skin and dull hair after showers
• Spotted dishes and glassware, even right out of the dishwasher
• Shortened lifespan for water-using appliances

The solution: A properly sized water softener works to help remove hardness minerals before they reach your faucets. The result? Softer water, longer-lasting appliances, cleaner dishes, and noticeably better showers.

We've served Santa Clara homeowners for 45+ years. Want to know exactly what's in your water? We'll test it for free.

Filters work continuously to improve your water… but they aren’t designed to last forever.

Over time, filters can become less effective as they capture minerals and impurities. Regular replacement helps maintain performance, ensuring your system continues to deliver the results it was designed for.

Replacement timing can vary depending on usage and water conditions, which is why routine maintenance is an important part of any water system.

Consistent care helps your system continue working the way it should.
