Troubleshoot Your Water Heater With Mullen Plumbing
Long Beach, United States – September 10, 2025 / Mullen Plumbing /
A water heater that refuses to heat can disrupt daily routines, from morning showers to dishwashing. For homeowners seeking water heater repair in Long Beach, CA, Mullen Plumbing offers expert solutions and practical advice. This post outlines simple steps to troubleshoot a water heater that’s not working, helping residents identify common issues before calling in the professionals.
Check the Power Supply
The first thing to investigate is whether the water heater is getting power. For electric water heaters, a tripped circuit breaker or blown fuse could be the culprit. Homeowners should check their electrical panel to ensure the breaker for the water heater is in the “on” position. If it’s tripped, resetting it might solve the issue, but frequent tripping suggests a deeper problem that needs professional attention.
For gas water heaters, ensure the gas supply is active. A shut-off valve may have been accidentally closed, or there could be an issue with the gas line. Mullen Plumbing, a trusted name for water heater repair in Long Beach, CA, advises checking these basics to rule out simple fixes before assuming a major malfunction.
Inspect the Pilot Light or Igniter
For gas water heaters, a common issue is a pilot light that’s gone out or an igniter that’s not functioning. If the pilot light is off, follow the manufacturer’s instructions to relight it safely, ensuring the gas valve is open. If it won’t stay lit, there could be a problem with the thermocouple, a safety device that detects the flame.
Modern units often use electronic igniters instead of a pilot light. If the igniter fails, the heater won’t produce hot water. Homeowners can listen for a clicking sound when the heater tries to ignite—if it’s absent, the igniter may need repair. Mullen Plumbing’s technicians are skilled at diagnosing these issues quickly, saving time and hassle.
Examine the Thermostat Settings
Sometimes, the issue is as simple as a thermostat set too low or malfunctioning. Most water heaters have a dial or digital display to adjust the temperature, typically set between 120°F and 140°F for safety and efficiency. If the water feels lukewarm, check the thermostat and increase it slightly if needed.
A faulty thermostat, however, might not respond or could misread temperatures, leading to cold water. For those in Long Beach, CA, Mullen Plumbing can test and replace thermostats to restore consistent heating, ensuring households enjoy reliable hot water.
Know When to Call a Professional
If these checks don’t solve the problem, it’s time to contact a plumber. Issues like a broken heating element, a damaged dip tube, or a failing gas valve require specialized tools and expertise. Attempting to fix these without proper training can be dangerous and may void warranties.
Mullen Plumbing’s team responds quickly to calls for water heater repair in Long Beach, CA, offering thorough diagnostics and lasting solutions. Their experts assess the unit’s age, condition, and repair costs to recommend whether fixing or replacing is the better option.

By checking these first, homeowners can save time and pinpoint the problem.
