What are the warning signs that a water heater is about to burst or explode?

• <div><p>While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:</p><ul><li><p><b>Sulfur or Rotten Egg Smell:</b> This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.</p></li><li><p><b>Leaking Pressure Valve:</b> If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.</p></li><li><p><b>Shaking or Rumbling:</b> Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.</p></li><li><p><b>Excessive Heat:</b> If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.</p></li><li><p><b>Rust-Colored Water:</b> This can be a symptom of severe internal corrosion that compromises the tank's integrity.</p></li></ul><p>If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.</p></div>

How much does water expand in a water heater?

• <div><p>Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed. </p></div>

What’s the best place in my house for a hybrid water heater?

• <div><p>Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.</p></div>

Q: Do water heater installation laws change in different states?

• <div><p>Every city and state will have its own set of installation codes and laws. Some won&rsquo;t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a <a href="https://www.angi.com/nearme/water-heater-installation/">local water heater installation company</a> and local building codes to confirm which permits are required and what the specific laws are.</p></div>

Q: Can you install an expansion tank anywhere?

• <div><p>No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There&rsquo;s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for. </p></div>

Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.
Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.
