Drinking Water From a Softener: Is There a Hidden Health Risk?

Written by Craig "The Water Guy" Phillips

While water softeners improve appliance performance, drinking softened water presents several health concerns. We've found that softened water adds 30-50 mg/L of sodium to your daily intake and removes beneficial calcium and magnesium minerals. In older homes, it can potentially leach lead from pipes. For healthier hydration, consider installing a bypass valve for drinking water or a reverse osmosis system with remineralization. The right water strategy balances convenience with long-term wellness.

Key Takeaways

• Softened water contains 30-50 mg/L additional sodium, which may affect those with hypertension or sodium restrictions.
• Water softeners remove beneficial calcium and magnesium that normally contribute 5-20% of daily mineral intake.
• Softened water can potentially increase lead exposure by leaching metals from older plumbing systems.
• Exclusively drinking softened water may increase cardiovascular disease risk due to mineral deficiencies.
• Installing a bypass valve or reverse osmosis system provides healthier drinking water while maintaining softening benefits.

The Sodium Factor: Understanding Salt Content in Softened Water

While most homeowners install water softeners to combat hard water issues, many don't realize they're introducing a new concern into their drinking water: sodium.

Typical water softening systems increase sodium levels by 30 to 50 mg/L or more—a significant addition that warrants attention.

Though an 8-ounce glass of softened water contains less sodium than a slice of bread, we shouldn't dismiss the cumulative effect.

For those with hypertension or on sodium-restricted diets, this additional intake can impact cardiovascular health over time.

What's equally concerning is what's removed: essential minerals like calcium and magnesium that our bodies need.

We recommend using a bypass valve for drinking water or installing a reverse osmosis system to enjoy the benefits of soft water without compromising your health.

Missing Minerals: The Impact of Calcium & Magnesium Removal

When water softeners remove hardness from your water, they also strip away something valuable: essential minerals your body needs.

These minerals—particularly calcium and magnesium—aren't just water impurities; they're dietary contributors providing 5-20% of your daily mineral intake.

We're now seeing evidence that exclusively drinking softened water may increase cardiovascular disease risk over time.

While you might assume a balanced diet compensates for this loss, research suggests otherwise. Many of us don't fully replace these minerals through food alone.

The nutritional impact becomes especially concerning for households using softened water for all their hydration needs.

Without these minerals, you're missing out on significant health benefits that naturally mineralized water provides.

That's why we recommend maintaining a separate unsoftened drinking water source or investing in remineralization technology.

Potential Plumbing Concerns: Lead Exposure From Water Softening

Although water softeners offer numerous benefits for household use, they introduce a concerning health risk many homeowners overlook: increased lead exposure.

This risk is particularly pronounced in older homes with aging plumbing systems, where softened water's corrosive properties can accelerate the leaching of lead and copper into your drinking water.

We've found that the sodium ions in softened water, which replace calcium and magnesium, gradually deteriorate plumbing materials over time.

Research confirms this markedly heightens lead exposure risk, especially for children and other vulnerable individuals.

If you're using a water softener, we strongly recommend regular water quality testing to monitor contaminant levels.

For those concerned about these risks, installing a reverse osmosis system provides effective protection by removing lead and other harmful substances from your softened drinking water.

Reverse Osmosis: A Solution for Healthier Drinking Water

For homeowners concerned about the safety of their softened water, reverse osmosis (RO) systems offer a compelling solution that effectively addresses multiple water quality issues simultaneously.

These systems excel at removing contaminants and excess sodium from softened water, creating a healthier drinking experience.

What's particularly valuable is how RO systems can be configured to reintroduce beneficial minerals like calcium and magnesium through remineralization processes.

This delivers water that's both pure and nutritionally balanced—less acidic and gentler on your digestive system.

Creating a Balanced Water Strategy for Your Home

Creating an ideal home water system isn't about choosing between softened or unsoftened water—it's about strategically implementing both to maximize benefits while minimizing health concerns.

We recommend using water softeners for your appliances and plumbing while installing a reverse osmosis system for drinking water, giving you the best of both worlds.

Protect your pipes, perfect your drinking water—the dual-system approach delivers benefits without compromise.

Regular maintenance is non-negotiable—both systems require consistent attention to prevent bacterial growth and guarantee optimal performance.

For those with hypertension or sodium-sensitive conditions, we suggest installing separate unsoftened water taps in key areas of your home.

Remember to tailor your approach to your specific water hardness level.

Frequently Asked Questions

Are There Health Risks Drinking Softened Water?

Yes, we've found softened water carries health risks from increased sodium levels, mineral deficiency, and potential plumbing corrosion that can leach harmful metals into what we're drinking.

Why Are States Banning Water Softeners?

We're seeing states ban water softeners because they release harmful chlorides into waterways, damage plumbing systems, and increase sodium in drinking water that violates health regulations and threatens freshwater resources.

Is Water Safe to Drink if You Have a Water Softener?

Yes, we're generally safe drinking softened water, but we'll want to monitor our sodium intake. If we're on sodium-restricted diets, let's consider using a bypass valve for drinking water.

Why Is Soft Water Not a Good Choice for Drinking?

We don't recommend drinking soft water because it's higher in sodium, lacks essential minerals like calcium and magnesium, and may leach lead or copper from your plumbing into your drinking supply.
