Introduction
A broken water heater doesn’t just mean cold showers—it can be a signal of bigger problems. The sooner you catch the warning signs, the easier (and less expensive) the fix tends to be. In this post, we’ll walk you through common trouble signs, what they mean, and what to do next if you’re in Concord, CA.
What Types of Water Heaters Are We Talking About?
There are two main kinds of residential water heaters—and they fail in different ways:
- Traditional tank water heaters: store hot water in a large insulated tank, always keeping a reservoir ready.
- Tankless water heaters: heat water on demand as it flows through heating elements and are typically more compact.
Each type has its quirks. Knowing which one you have helps you spot issues early. topnotchplumberconcordca.com
Early Warning Signs to Watch
Here are the red flags related to both tank and tankless heaters. If you detect any, don’t wait—seek a professional diagnosis.
| Sign | What It Usually Means | What to Do Immediately |
|---|---|---|
| No hot water | Heating element failure, gas supply issue, or ignition problems in gas units. topnotchplumberconcordca.com | Check power/gas supply; if all seems fine, call for a repair. |
| Insufficient hot water | Sediment buildup in tanks, scaling in tankless units, or a failing thermostat. topnotchplumberconcordca.com | Flush tank or descale unit; test thermostat. |
| Strange noises (rumbling, popping, banging) | Mineral/sediment buildup, especially in tank units, making heating inefficient and noisy. topnotchplumberconcordca.com | Schedule cleaning or flushing services. |
| Leaks around base | Could mean loose pipes, failing pressure relief valve, or even a crack in the tank. topnotchplumberconcordca.com | Shut off water, contain water to avoid damage, contact repair. |
| Cloudy, rusty, or bad-smelling hot water | Corrosion inside the tank; bacteria buildup; sometimes issues with water supply. topnotchplumberconcordca.com | Avoid using water; get professional help. |
| Pilot light or ignition problems (gas units) | Faulty thermocouple, gas supply issue, or sensor failure. topnotchplumberconcordca.com | Don’t try adjusting gas lines yourself; call a technician. |
| Temperature & Pressure Relief (T&P) Valve dripping | Tool for safety—constant dripping means something is off (pressure, temp, or valve itself). topnotchplumberconcordca.com | Place bucket under valve; schedule inspection. |

- Monitor water temperature & how long it takes to get hot water
- Look around base for moisture or puddles
- Inspect valves and connections for visible leaks or corrosion
- Smell the hot water (any “off” smells?)
- Watch for rust or color changes in water
These observations will help when you speak with a technician—having details about what you’ve seen/spotted can lead to faster diagnosis & repair.
When to Call in a Specialist (Not DIY)
Some tasks you might try yourself (e.g. flushing a tank, checking valves), but others are safer or more effective when handled by a professional:
