Your water heater is an essential part of your plumbing system. It provides you with hot water and ensures that you can take a comfortable shower, wash dishes, do laundry, and more. However, when a water heater is reaching the end of its life span, it can become a safety hazard. A water heater explosion can cause significant damage to your home and put you and your family in harm’s way. If you want to avoid that, here are the warning signs that your water heater is going to explode.

Rusty Water

If you start to notice rust-colored water coming from your hot water tap, it could indicate the inside of your water heater has begun to rust. Rust can weaken the tank, making it more likely to burst. If you notice discolored water, call a professional plumber to replace the water heater immediately.

Strange Noises

A water heater should make minimal noise. If you hear popping, cracking, or hissing sounds coming from the water heater, it’s potential your water heater is overworking to keep up with your daily usage. The extra pressure could cause the tank to crack or burst. You’ll want to call a professional plumber to address the issue.

Leaking Water

If you find a pool of water around the base of your water heater, it’s a sign that the tank has become rusty and corroded. The tank will weaken where the corrosion happens, and it can be susceptible to sudden burst or leak. This should be addressed immediately.

Hot Water is Running Out

Is the hot water seemingly vanishing quickly in your home? This could mean your tank is struggling to keep up with the demand for hot water. The extra pressure can cause a rupture, meaning a professional inspection will need to be performed.


The typical water heater lasts between 8 to 12 years. If your water heater is approaching the older end of that range or exceeding it, it’s best to get the heater inspected by a professional. An older water heater is more prone to unexpected failures or leaks leading to an explosion.


Your water heater is not something you want to be taken lightly. It’s part of your daily routine and necessary for your daily living. By knowing the warning signs that your water heater is going to explode, you can protect your home from a potential disaster. When in doubt, call a professional plumbing service to conduct an inspection and recommend the proper course of action. Don’t let a water heater explosion turn into an emergency – take proactive steps to keep your home safe.
