Not Every Water Heater Problem Means You Need a New Unit
A water heater that stops producing hot water does not automatically need to be replaced. Many common issues can be repaired quickly, allowing your existing system to continue operating safely and efficiently.
Every service call at C.A.B. Backflow begins with a thorough diagnosis. Rather than recommending replacement based solely on the age of the unit, we inspect the water heater to determine what caused the problem and whether a repair is the most practical solution.
With more than three decades of experience, our plumbers repair:
- Traditional tank water heaters
- Tankless water heaters
- Gas water heaters
- Electric water heaters
By identifying the source of the issue first, we can recommend repairs that match the condition of your equipment and your long-term needs.
Repair symptoms
Symptoms That May Point to a Water Heater Repair Need

- Error codes on a tankless system

- Increased energy bills without another explanation
If your water heater is showing any of these symptoms, our team can inspect the system and determine the cause.

OUR PROCESS
Repair vs. Replacement: How We Make the Recommendation
One of the most common questions customers ask is whether it makes sense to repair an existing water heater or replace it. Our recommendations are based on the actual condition of the equipment rather than a one-size-fits-all approach.
01
Age of the Unit
Most traditional water heaters have an expected service life of approximately 10 to 12 years. If the unit is approaching or exceeding that age, investing in major repairs may not provide the best long-term value.
02
Repair Cost Compared to Replacement
If the estimated repair cost exceeds roughly 50 percent of the cost of installing a new water heater, replacement often becomes a more practical investment. We explain both options so you understand the long-term value of each.
02
Frequency of Previous Repairs
A water heater that has required several recent repairs may be experiencing overall system wear. Repeated breakdowns often indicate that additional failures could occur in the near future.
02
Availability of Replacement Parts
Some older water heaters contain discontinued components that are difficult or impossible to obtain. In these situations, replacement may be the most realistic solution.

What can we do for you?
How long does a typical water heater repair take?

Will you tell me if my water heater is not worth repairing?

Can you repair both gas and electric water heaters in Gurnee?
Yes. Our experienced plumbers repair both gas and electric water heaters, including traditional tank systems and many tankless water heater models.
My pilot light keeps going out. Is that a repair or a replacement situation?
A pilot light that repeatedly goes out is often caused by a repairable issue such as a faulty thermocouple, gas control valve, or burner component. After inspecting the system, we can determine whether a repair is appropriate or if replacement should be considered.
