7 Signs Your Water Heater Needs Replacing

Most homeowners don’t think about their water heater until the morning the shower runs cold. In Hampton Roads, a standard gas or electric tank typically lasts 8 to 12 years, and our moderately hard water plus summer humidity can shorten that. Knowing the warning signs lets you replace the unit on your schedule instead of in an emergency.

1. The tank is more than 10 years old

Look for the serial number on the label — most manufacturers encode the month and year in the first few characters. If your tank is past the decade mark, start budgeting for a replacement even if it seems fine.

2. Rusty or discolored hot water

Rust-colored water only on the hot side usually means the inside of the tank is corroding. Once the glass lining fails, a leak is not far behind.

3. Rumbling, popping or banging

Sediment settles on the bottom of the tank and hardens. As the burner or element heats through it, you hear popping. Annual flushing helps, but loud noises in an older tank are a sign of wear.

A water heater rarely fails all at once. It usually gives you months of small warnings — the trick is noticing them.

4. Water around the base

Check the fittings and relief valve first — those can be repaired. If water is coming from the tank itself, it needs to be replaced.

5. Not enough hot water

If the hot water runs out faster than it used to, the tank may be full of sediment or a heating element may have failed. If your household has grown, the tank may simply be too small.

6 & 7. Rising bills and frequent repairs

An aging water heater works harder to deliver the same hot water. If you are calling for repairs every year, a new high-efficiency tank, tankless or heat-pump unit will usually pay for itself. Tidemark Plumbing can compare options with you and give you a written quote the same day.
