Water is one of the few things in RV life that can quietly ruin your day, your week, or your entire season. RV water issues don’t always show themselves dramatically. More often, it whispers. A drip. A damp corner. A smell you can’t quite place.
Over the past five years, I’ve learned a lot about protecting my rigs, Bessie, Bertha, and now Bertie Bea, from water and temperature-related damage. Some lessons were preventative. Others were learned the hard way.
Bertha eventually received a new roof from Flex Armor Greensboro. Bertie Bea, on the other hand, has benefited from something just as important: early detection and layered monitoring.
Full-Time RV Living Demands Early Warning Systems
When you live in your RV full-time, water systems are always in use. Showers, sinks, toilets, city water connections, and hidden plumbing behind walls all see daily stress.
The problem isn’t usually a catastrophic failure. It’s the small, persistent leaks that go unnoticed until damage is already done.
That’s why I’ve stopped relying on a single solution and instead built a layered water leak detection strategy to detect RV water issues.
Why I Now Use Two Different Water Leak Detection Systems to Protect Against RV Water Issues
On Bertie Bea, I’m currently running two complementary leak detection systems, each with its own strengths.
Wireless Coverage Where It Makes Sense
I use water leak sensors from AiDot in several strategic locations throughout the coach, including:
- Under-sink water lines
- Interior low points where water would collect first
These sensors are easy to place, quick to deploy, and extremely loud when triggered. When one alarms, there’s no mistaking it. Push notifications and text alerts tell me exactly which sensor detected moisture, and the mobile app provides real-time visibility into what’s happening inside the rig.
Wired Detection Where Precision Matters Most
In addition to the AiDot sensors, I’ve installed Moen wired water leak detectors at locations where precise placement is critical to preventing RV water issues.
The most prominent example is under the shower.
The Moen sensor’s wired probe allows me to position the detection point exactly where water would first appear, not just where a puck-style sensor can sit. That distinction matters in tight RV spaces where plumbing, framing, and drain pans all compete for room.
This setup has already proven its value.
A Real-World Example From the Wet Bay
One of the Moen sensors is installed in the wet bay. It’s been consistently detecting a small amount of moisture in an area that, by design, is technically “wet.”
Here’s the key takeaway:
Even in areas designed to handle moisture, unexpected water still matters.
The sensor has confirmed that:
- There is a slow, persistent leak
- It’s happening consistently
- It’s not yet migrating beyond the wet bay
While I haven’t located the exact source yet, knowing when and where water is appearing allows me to monitor the situation closely and prevents the leak from becoming a surprise elsewhere.
That awareness alone is worth the investment.
Why Early Detection Beats Perfect Repairs
Every RV owner wants permanent fixes. But the reality is that some issues take time to track down, especially slow leaks that only appear under certain conditions.
Water leak sensors give you:
- Time to diagnose instead of react
- Proof that a problem exists, even when it’s intermittent
- Confidence that a small issue hasn’t become a big one
Catching moisture early often means the difference between:
- Drying an area vs. rebuilding it
- Replacing a seal vs. replacing flooring
- Enjoying your trip vs. canceling it
Final Thoughts
Protecting an RV from water damage isn’t about one perfect product. It’s about coverage, redundancy, and awareness.
By combining wireless sensors for broad monitoring with wired sensors for precise detection, I’ve built a system that works with how RVs actually live and move.
Water issues will always be part of RV life. The goal isn’t perfection. It’s knowing what’s happening before damage has a chance to take hold.
Stay ahead of the leaks, and you stay on the road.
