Water Heater Repair: 5 Signs You Need Professional Help

Is your hot shower turning cold too fast? Hearing strange rumbling from your water heater?
You might be facing early signs that your water heater needs repair. For Colorado, homeowners in places like Denver, Golden, Arvada, Lakewood, and Westminster, dealing with hot water problems during the colder months can quickly become an emergency.

Knowing what to watch for can help you avoid a complete breakdown – and even extend the life of your system.

In this post, our experts at Mac-Vik Plumbing, Heating, Cooling, Electrical, and Air Conditioning share the top warning signs your water heater might need repair, and what to do about it.

1. Inconsistent Water Temperature

Are you getting hot water one minute, then freezing cold the next?
That’s a red flag. Inconsistent temperatures can mean:

A failing heating element (in electric models)
Sediment buildup in the tank
A faulty thermostat

If you’re constantly adjusting the faucet or running out of hot water too soon, it’s time to call a professional for water heater repair.

2. Water Heater Leaking or Pooling Water

Notice a puddle forming under or around your water heater? That’s not something to ignore.
Leaks can come from:

Loose connections
Faulty temperature and pressure (T&P) relief valve
A corroded tank (which usually means full replacement is needed)

Pro tip: Shut off the water supply and call a licensed plumber ASAP – especially during freezing Colorado winters where leaks can escalate into burst pipes.

3. Strange Noises: Popping, Rumbling, or Banging

If your water heater sounds like it’s boiling rocks, you probably have a sediment issue.
Minerals in Colorado’s hard water can settle at the bottom of the tank, creating a layer that traps heat and causes the metal to overheat. This leads to rumbling or popping sounds and reduces energy efficiency.

Sediment buildup not only shortens the life of your system – it can also increase your utility bills. A professional flush might be all you need to fix it.

4. Rust-Colored Water or Metallic Smell

Turn on the tap and see rusty or discolored water? That’s likely corrosion inside your water heater tank or the anode rod failing.
You may also notice a metallic smell or taste in the water.

If flushing the system doesn’t help, your unit may be deteriorating from the inside out- and it’s time for expert repair or replacement.

5. Higher Energy Bills

Water heaters running inefficiently tend to work harder—and cost more.
If you haven’t changed your water usage but your utility bills are going up, your system could be the culprit.

Repairing failing parts or cleaning out sediment can often restore performance and save you money.

Bonus Tip: The age of Your Water Heater

Most traditional tank water heaters last 8–12 years. If yours is pushing that limit (or past it), frequent repairs may not be worth it.
Our team at Mac-Vik can inspect your unit and recommend whether it’s more cost-effective to repair or replace.
