When your water heater stops working the way it should, it can throw off your whole day.

We have spent over a decade serving our community with dependable plumbing service built on courtesy, respect, and professionalism.

Our goal is to restore your hot water quickly while protecting your home, your plumbing system, and your budget.
What this service includes
Our tank and tankless water heater repair service starts with a careful inspection of the unit and the full system. We check the heater itself, water connections, shut-off valves, gas lines when applicable, venting, electrical components, safety devices, and overall performance. Once we identify the issue, we explain what is happening in plain language and recommend the most practical repair options.
We repair many common water heater problems, including:
- No hot water or inconsistent hot water
- Water that is not heating to the right temperature
- Running out of hot water too quickly
- Pilot light issues on gas water heaters
- Burner, igniter, or thermocouple problems
- Faulty heating elements on electric water heaters
- Malfunctioning thermostats or temperature controls
- Tank leaks and water line leaks
- Pressure relief valve issues
- Sediment buildup inside the tank
- Rumbling, banging, or popping noises
- Rust-colored or foul-smelling hot water
- Low hot water pressure
- Error codes and sensor issues on tankless systems
- Mineral scale buildup in tankless heat exchangers
Tank water heater repair
Traditional tank water heaters are still one of the most common systems in homes. These units store and heat a set amount of water, usually in gas or electric models. Over time, normal wear can affect heating elements, thermostats, gas controls, valves, drain components, and internal tank performance. Sediment can also collect at the bottom of the tank, making the unit less efficient and causing noise or reduced hot water capacity.
When we repair a standard storage tank water heater, we focus on both the immediate problem and the overall condition of the system. If a heating element has failed, the pilot assembly is not staying lit, the thermostat is inaccurate, or a valve is leaking, we work to restore safe and reliable operation. We also look for warning signs that may point to bigger issues, such as corrosion, excessive pressure, or age-related wear.
Tankless water heater repair
Tankless water heaters are energy-efficient and convenient, but they need the right diagnosis when problems come up. Unlike a storage tank unit, a tankless water heater heats water on demand. These systems rely on specialized components such as flow sensors, control boards, burners, ignition systems, heat exchangers, and ventilation or exhaust systems. Even small issues can affect performance.
Our tankless water heater repair service covers common issues like fluctuating temperatures, ignition failure, mineral buildup, restricted flow, system lockouts, and error code troubleshooting. In many homes in Fallbrook and nearby areas, hard water can lead to scale buildup inside tankless units. This can reduce efficiency, trigger faults, and shorten the life of the system if it is not addressed. We inspect the unit thoroughly and recommend the repair or maintenance needed to get it running properly again.
Common signs your water heater needs repair
Many water heater problems start small and get worse over time. Calling early can help prevent water damage, higher utility bills, and unexpected breakdowns. You may need water heater repair if you notice:
- Hot water takes too long to arrive
- Your showers turn cold faster than normal
- The water heater makes loud or unusual sounds
- You see water pooling near the unit
- The pilot light keeps going out
- Your tankless system displays an error code
- Hot water has a rusty color or odd smell
- Your utility costs increase without a clear reason
- The temperature is hard to control
If you are seeing any of these issues, our team can inspect the system and help you decide on the next step.
Our repair process
We believe good service starts with clear communication and honest work. When you call Sheldon Plumbing for tank or tankless water heater repair, we arrive ready to diagnose the issue and provide a practical solution. We focus on punctual service, competitive pricing, and quality workmanship on every job.
- System inspection: We assess the water heater, plumbing connections, fuel or power source, venting, and safety components.
- Problem diagnosis: We identify the root cause of the failure or poor performance.
- Clear explanation: We explain what we found in simple terms and answer your questions.
- Recommended repair: We provide the best repair options based on the condition, age, and type of unit.
- Testing and verification: After the repair, we test the system to confirm safe operation and proper hot water performance.
Repair vs. replacement
Not every water heater problem means you need a new unit. Many issues can be repaired cost-effectively, especially when they are caught early. If the unit is in otherwise good condition, a targeted repair may restore reliable performance and extend its lifespan.
That said, if the tank is heavily corroded, leaking from the body of the unit, or nearing the end of its service life, replacement may be the better long-term value. We will always give you honest guidance. Our job is not to push a service you do not need. We help you weigh the age of the unit, repair cost, energy efficiency, and expected performance so you can make the right decision for your property.
Residential and commercial service
We repair both residential and commercial water heaters. From family homes to local businesses, we understand that reliable hot water is essential. If your business depends on hot water for staff, customers, cleaning, or operations, a failed water heater can create major disruption. We work to restore service as quickly as possible and minimize downtime.

- How do I know if my water heater needs repair or full replacement?
In many cases, a repair is all you need. If your tank or tankless water heater is making strange noises, not heating enough water, taking too long to recover, leaking from a fitting, or showing error codes, we can inspect it and tell you what makes the most sense. If the unit is older, has major internal damage, or needs frequent repairs, replacement may be the better long-term value.

We work on residential and commercial water heater systems and use quality parts to make lasting repairs.
- What should I do if my water heater is leaking?
If you see water around your unit, don’t ignore it. A small leak can quickly turn into water damage. If it’s safe to do so, shut off the water supply to the heater and call us right away.
