5 Signs It’s Time to Replace Your Water Heater

October 1, 2025

Your water heater works quietly in the background — until it doesn’t. When it fails, you’re left with cold showers, frustrated family members, and possibly even water damage. In Santa Monica, where many homes have older plumbing systems, knowing the warning signs of a failing water heater can save you from an unexpected breakdown.

1. Your Water Heater Is Over 10 Years Old

Most traditional tank water heaters last between 8–12 years. After that, efficiency drops, parts wear out, and the risk of leaks increases. If yours is pushing past the decade mark, it’s smart to plan for replacement before you’re left without hot water.

2. Rusty Water

If you notice brown or rusty water coming from your hot water taps, corrosion may be occurring inside your water heater tank. This is often a sign that the tank is nearing the end of its life.

3. Strange Noises

Popping or rumbling sounds usually mean sediment has built up in the tank. Over time, this sediment hardens, reducing efficiency and potentially causing damage.

4. Not Enough Hot Water

If your showers are turning cold sooner than they used to, your water heater may be losing capacity. Sediment buildup or failing heating elements are common culprits.

5. Leaks Around the Tank

Even small leaks can cause major water damage. If you notice water pooling at the base of your heater, call a professional immediately.
