Why are water heater earthquake straps important?

It’s crucial to understand the potential risks associated with installing materials and gadgets. Especially in areas susceptible to harsh weather or destructive natural events. For example, in regions prone to earthquakes, it’s essential to fasten and stabilize your water heater to prevent it from toppling during seismic activity. That’s when water heater earthquake straps come in handy. 

When earthquakes happen, they can reveal issues in buildings and utility lines that we might not notice otherwise. These problems can make natural disasters even worse, causing damage to property and putting people at risk of getting hurt.

Here, we will learn about the impact of earthquakes on water heaters. And, how to ensure the water heater installations can withstand the seismic shaking.

What are water heater earthquake straps?

Water heaters, found in almost every home, can be seriously affected by earthquakes if not properly secured to the wall. Water heater earthquake straps are safety devices designed to secure these heaters in place during seismic activity. 

These straps are typically made of sturdy materials such as metal or heavy-duty nylon. They are installed to prevent the hot water heater from tipping over or moving during an earthquake.

How do water heater earthquake straps help prevent damage?

The purpose of these straps is to minimize the risk of damage and potential hazards associated with an unsecured water heater. In the event of an earthquake, if a water heater were to topple over, it could result in gas or water leaks, fires, or other safety hazards.

It could break the pipes and supply lines, letting flammable gas escape. The tiny pilot light in the water heater can then light up the gas, starting a fire that quickly spreads to nearby buildings.

The installation of earthquake straps involves securely attaching the straps to the water heater and then anchoring them to the wall or a stable support structure. The straps are typically placed horizontally and vertically around the water heater, forming a secure webbing that holds the appliance firmly in place.

Keep in mind that it’s important to follow manufacturer guidelines and local building codes when installing earthquake straps to ensure proper placement and effectiveness. Additionally, regular inspections and maintenance checks should be conducted to ensure that the straps remain intact and in good condition.

Is there a building code requirement for water heater restraints?

After the 1994 earthquake in California, officials found that a majority of home fires were caused by water heaters tipping over. This happened because the straps meant to hold the water heaters in place were not good enough or sufficient. 

California accepted the seriousness and even passed a law saying that all new water heaters must be properly braced. This law is part of the building code in seismic zones, which include not only California but also parts of Alaska, Nevada, Idaho, Wyoming, Montana, Oregon, Washington, and Hawaii.

How to secure water heater straps?

Here are the steps to secure your heater. Always adhere to the manufacturer’s guidelines and recommendations provided with the earthquake straps. If you are uncertain, consider hiring a professional plumber for proper and secure installation. And, it goes without saying that you should only buy a tested and recognized water heater. 

• Gather the required materials such as earthquake straps, screws, a wrench, and a screwdriver.
• Locate strapping points about one-third from the top and bottom of the water heater.
• Place straps over the points, adjusting their length to fit snugly around the heater.
• Use screws to firmly attach the ends of the straps to the wall or structural support.
• Tighten the straps using a wrench to ensure a secure grip on the heater.
• If using more straps, repeat the process for even distribution.
• Double-check and ensure the straps are tightly secured to withstand potential movement during earthquakes.
• Periodically inspect straps for wear or damage, making adjustments as necessary to maintain safety.

Last thoughts

Water heater earthquake straps are like safety belts for your water heater. They are strong bands that hold the heater in place during earthquakes, preventing it from falling or getting damaged. It’s a simple way to keep your water heater secure and avoid potential disasters.
