When your water heater malfunctions, it brings your daily routine to a grinding halt. As the trusted experts at Plumbing Plus serving all of San Diego County, we specialize in diagnosing and fixing these issues fast. Here are four common issues that frequently require expert attention.
Four Common Water Heater Repairs

Leaking Tank or Connections
A leak is the most obvious sign of a problem. If water is escaping from the tank itself, the metal is likely corroded, and the entire unit needs replacement. Leaks around the inlet or outlet connections, however, may just need a quick tightening or a new fitting. In either case, you need to call for professional water heater repair in San Diego immediately to prevent serious water damage to your home.

Pilot Light or Ignition Failure
For gas units, if the pilot light goes out (often due to a faulty thermocouple or gas valve), or if an electric unit's ignition fails, your water will stay cold. While relighting a pilot can sometimes be a simple fix, persistent failure points to a deeper issue. Never attempt complex gas or electrical repairs yourself; trust our skilled technicians to safely diagnose and repair the fault.

Rumbling or Noisy Operation
Strange noises like rumbling, popping, or grinding often indicate sediment buildup inside the tank. Over time, mineral deposits settle at the bottom, overheat, and cause this noise while drastically reducing your unit's energy efficiency. Regular flushing and maintenance can prevent this, but severe buildup may require professional cleaning or could lead to premature tank failure, necessitating a full replacement.

Inconsistent Water Temperature
If your hot water runs out too quickly, or if the water is scalding hot, the thermostat may be failing, or the heating elements could be malfunctioning. These components are vital for safe, consistent operation of your water heater in San Diego. Because these are high-voltage and precision parts, they should only be replaced by certified professionals who can ensure correct installation and safety.
