Bypassing a Hot Water Heater: Why and How

Introduction to Hot Water Heater Bypass

Every household relies on a hot water heater for daily needs, such as showering, washing dishes, and cleaning laundry. However, there might be instances where you need to bypass the hot water heater. This might be for maintenance, repair, or even simply to bypass it when you don't need hot water in those pipes. In this article, we will discuss when and how to bypass a hot water heater, focusing on safety and practicality.

Why Bypass a Hot Water Heater?

1. Safety and Maintenance Concerns

One critical reason to bypass a hot water heater might be due to a leak. Years of use can lead to wear and tear, and a 20-year-old heater, as mentioned, can become a liability. When a hot water heater starts leaking, it can cause extensive damage, water waste, and, in severe cases, flooding. It's advisable to bypass the leaking heater until you can replace it to prevent further potential damage to your home.

2. Preventing Burst Pipes

Another reason to bypass the hot water heater is to prevent the pipes from bursting, especially during cold weather conditions. If you leave home for an extended period and the heater remains on, it can cause significant damage if the pipes freeze and burst. By bypassing the system, you can avoid this issue by preventing water from flowing through the pipes.

How to Bypass a Hot Water Heater

1. Shutting Valves and Depressurizing

The first step in bypassing a hot water heater is to shut off the isolation valves. Open the drain spigot for a few seconds to depressurize the system, and then shut it down. This step is essential to ensure that no water pressure remains in the pipes and to prevent any accidental release of water.

2. Disconnecting Hoses

Next, disconnect the inlet and outlet hoses. Use a 3/4” pipe nipple to bridge the disconnected ends of the pipes. This step is crucial to isolate the hot water heater from the rest of the system, ensuring that no water flows through the bypassed heater.

3. Cutting Pipes and Reconnecting

If you want to bypass the hot water heater for an extended period or permanently, you can cut the inlet and outlet pipes. Then, connect the two ends of the pipes to create a direct water flow bypass. This method will prevent the water from flowing through the heater and can be useful if you have a specific reason to avoid using it for a prolonged time.

But, Why Bypass a Hot Water Heater?

It's worth noting that there are limited reasons to bypass a hot water heater in a residential setting. If you have access to unlimited hot water or simply don't need it at the moment, turning off the heater might be sufficient. However, if you're considering bypassing the heater for extended use or for maintenance purposes, be cautious and ensure you follow the proper safety protocols.

Conclusion

Bypassing a hot water heater can be a practical solution in certain situations, such as when the heater is leaking or during cold weather when you're away from home. However, it's essential to understand the implications and follow the proper safety measures to prevent potential damage. Always prioritize safety and consult professional help if you're unsure about the process.
