Welcome back to another Two-Minute Tech Tip Tuesday, brought to you by the National RV Training Academy (NRVTA) – the largest hands-on RV training academy in America! Today’s tip is all about something we get asked a lot: Is it really safe to use bleach to sanitize your RV’s fresh water system?
Let’s dive into it.
🚨 The Short Answer: YES – With Proper Use
Hi, I’m Todd, and I’m here at the National RV Training Academy to finally put this question to rest (hopefully for good).
Yes, using bleach water is absolutely safe for sanitizing your RV water system – as long as it’s used in the proper amounts. It’s not just RV folklore. This is established science and backed by some of the most respected safety organizations in the world.
So, where’s the confusion coming from? Let’s break it down.
⚖️ Bleach: Safe When Used Correctly
Here’s the truth: we still see people online hawking alternative products while claiming that bleach is unsafe. And while we’re not here to knock your preference for other sanitizers – let’s be clear:
Bleach is the only product approved for potable water sanitization by:
- NSF (National Sanitation Foundation)
- ANSI (American National Standards Institute)
- FDA (Food and Drug Administration)
- EPA (Environmental Protection Agency)
So, if you’re claiming bleach is unsafe across the board, you’re going up against all four of these major regulatory bodies. That’s a pretty tall order.
🧪 The Science: It’s All About the Dosage
Now, here’s where people get into trouble: using too much bleach.
Yes, bleach is a caustic chemical. If you go overboard, it can:
- Damage rubber components in your water system
- Affect the taste of your water
- Be unsafe for consumption
But at the right concentration? It’s not only safe, it’s highly effective.
💡 Proper dilution rate:
- 1/4 cup of plain, unscented bleach per 15 gallons of water
- OR 1 cup per 50 gallons of water
That gives you approximately 50 parts per million (PPM) – the recommended level for safe and effective sanitization.
🕐 Let it sit for 8 hours, then flush your system thoroughly with clean water.
💰 But What About Other Products?
If you prefer another product or brand – go for it. Many alternatives are simply derivatives of bleach or hydrogen peroxide. They may work just fine, but often:
- They’re more expensive
- They haven’t been tested and approved by the FDA, NSF, ANSI, or EPA for potable water use
That’s not to say they’re bad – just not proven to the same extent.
And hey, if you personally don’t want bleach in your water lines? That’s valid. But claiming it’s universally unsafe? That’s misinformation.
🔧 Final Word from Todd
“I get it – some folks were taught differently, and that’s okay. Just remember, we’re talking about science-backed best practices here. At the proper concentration, bleach is not only safe – it’s the gold standard for sanitizing your RV’s water system.”
If you’re seeing content out there telling you otherwise, just ask: Has this product been tested and approved by the same agencies?
If not, take it with a grain of salt (or a splash of bleach 😄).
