Know the warning signs
Signs Your Water Heater
Needs Attention
No hot water or inconsistent temperatures
Water that never gets hot, runs out quickly, or swings between hot and cold can point to a problem with the heating components, the controls, or the unit itself.
Water around the unit
Moisture or pooling near the heater can come from a loose connection, a fitting, or the tank. If water is actively leaking, have a professional look at it promptly.
Unusual noises
Popping, rumbling, or banging sounds are sometimes linked to sediment or scale building up inside the unit.
Rust-colored or discolored hot water
Discolored hot water can have more than one cause, including the heater or the pipes. An inspection helps narrow down the source.
Pilot light, ignition, or burner problems
A gas unit that will not stay lit or will not ignite should be checked by a licensed plumber. If you smell gas, leave the area and call your gas utility or 911.
Aging equipment or repeated issues
Older units and repeated repairs deserve a closer look. Age alone does not always mean replacement; it depends on the condition of the unit.

Your options
Repair Or Replace?
We’ll Help You Understand Your Options.
When Repair May Make Sense
Some water heater problems can be handled by inspecting and repairing individual components, such as controls, valves, or connections. Whether repair makes sense depends on the issue and on the overall condition of the unit.
When Replacement May Be Recommended
Replacement may be recommended when a unit is severely damaged, aging, inefficient, or repeatedly malfunctioning. Manufacturer warranty coverage, where it applies, depends on the product and its terms.
The right recommendation depends on your specific installation and equipment. Romero Bros will explain the options so you can decide what works best for your home.

Customer reviews
What Our Customers Say
“We had our water heater go out late last night. The next day I called a few plumbers and they're the only ones to answer and help me troubleshoot it before even coming out. They showed up within a few hours of me contacting them and provided great customers service. He got our water heater working and even added a part (can't remember the name of it) to bring it up to code. I would HIGHLY recommend ROMERO BROS. I will be a customer for life!”
