The Perils of Turning Off Your Home’s Emergency Water Valve
Many homeowners are tempted to shut off the emergency water valves to their toilets and faucets to prevent leaks or conserve water during a prolonged absence. While this might seem prudent, it can lead to significant and unexpected problems. Here’s why you should generally avoid this practice:
Hidden Leaks and Silent Damage
Emergency water valves are just that. They are designed to provide a quick shutoff of the water and are not intended for multiple repeat uses. Emergency valves are designed with “plunger type” shutoff, not ball valves.
Slow Drips and Undetected Issues: Even a minor leak, like a dripping faucet or a slow toilet fill, can go unnoticed if the emergency water supply is not closed correctly. This can lead to hidden damage over time.
Mold and Mildew: Stagnant water in pipes can become a breeding ground for mold and mildew, potentially leading to health issues and foul odors.
Corrosion and Pipe Deterioration: Shutting off the emergency water supply can accelerate corrosion within the pipes, especially in older plumbing systems. This can weaken the pipes and increase the risk of leaks or bursts when the water is turned back on.
Repair and Replacement Headaches
Difficulty in Identifying Leaks: Pinpointing the source of a leak can be challenging when the water supply is shut off. This can lead to unnecessary plumbing investigations and costly repairs.
Water Hammering: When the water supply is suddenly turned back on after a prolonged period, it can cause a phenomenon known as “water hammering.” This occurs when a sudden surge of water slams against valves and fixtures, potentially damaging them.
When to Consider Shutting Off Valves (not at the device)
Leaving for an Extended Period: We suggest that the main water valve at the home be shut off at the source.
However, it’s crucial to
Inspect Thoroughly: Before and after shutting off the water supply, check for leaks or signs of damage.
Turn On Faucets Slowly: When turning the water back on, do so slowly to minimize the risk of water “hammering” the pipes.
Monitor for Leaks: Regularly check for leaks after returning home.
In Conclusion
While shutting off emergency water valves under the sinks or at the toilet might seem sensible, the potential risks often outweigh the benefits. It’s generally advisable to leave these valves open to ensure the proper functioning of your plumbing system, prevent hidden damage, and maintain a safe and reliable water supply in your home.
