Top 5 Signs You Need a New Water Heater (Before It Fails!)

Hot water is something we all take for granted—until it runs out in the middle of a shower. At In A Flash Heating & Plumbing, we’ve helped countless homeowners across Medford, Somerville, Malden, and the Greater Boston area replace failing water heaters. Knowing the warning signs early can save you from cold showers, water damage, and emergency calls.

Here are the top five signs it’s time to think about a new water heater:

1. Your Water Heater Is Over 8–12 Years Old

Most traditional tank water heaters last about a decade. If yours is pushing past that age, it’s only a matter of time before leaks or efficiency issues show up.

👉 Check the manufacture date on your unit’s label. If it’s older than 10 years, consider replacement.

2. Rusty or Discolored Water

Notice brown or rusty water when you turn on the hot tap? That’s a major sign of internal corrosion inside your water heater tank. Corrosion means leaks are on the horizon.

3. Strange Noises (Popping or Rumbling)

Over time, sediment builds up at the bottom of your tank. When the water heats, it causes popping, banging, or rumbling sounds. Not only does this reduce efficiency, but it also shortens the lifespan of the unit.

4. Inconsistent or Not Enough Hot Water

Running out of hot water faster than usual? Or maybe the water’s lukewarm even with the dial turned up? That’s a classic signal your water heater is on its way out.

5. Leaks Around the Tank

Even the smallest leak can quickly turn into a big problem. If you see water pooling around your tank, call a plumber right away—this usually means the tank has cracked and needs replacement.

Don’t Wait Until It Breaks

Replacing your water heater before it fails completely can save you from major headaches (and costly water damage). Whether you need a standard tank model or want to upgrade to a tankless water heater, our licensed pros at In A Flash Heating & Plumbing have you covered.

We proudly serve Medford, Somerville, Malden, Everett, and all surrounding Massachusetts communities.
