Water Heater Repair in Fort Collins, CO | Bluewave Plumbers
The water heater is leaking in the garage. The pilot light went out and will not reignite. The drain pan has water in it. You turned on the shower and nothing came out hot. These are the calls we get every day — and we show up, diagnose the problem, and try to repair the unit before we talk about replacing it.
Fort Collins Water Heater Repair — Tank and Tankless
Bluewave services tank and tankless units running on gas and electric power. We repair before we replace. If your unit can be fixed at a reasonable cost, you will hear that first.
We are a plumbing-only company. Licensed Colorado plumbers, same day available. If you already know the unit needs to come out, see our water heater installation page.
How do I know if my water heater needs repair or replacement?
We assess it on site before recommending either. Leaks at the supply line, a failed heating element, and most pilot light issues are repairable. A corroded tank body, a unit 12 to 15 or more years old in Fort Collins hard water conditions, or a unit that has failed repeatedly usually calls for replacement. We give you the repair cost and the replacement cost in writing so you can decide.
Signs Your Fort Collins Water Heater Needs a Plumber
Any of the following is a reason to call today. Do not wait for a full failure or a flooded floor.
Call now if you see:
-
The water heater is leaking
From the tank body, a supply line connection, or the pressure relief valve — any active leak needs same day attention.
-
The unit is leaking in the garage and water is spreading across the floor.
Turn off the cold water inlet valve at the top of the tank and call immediately.
-
No hot water at any fixture in the house
With no recent changes to the system.
-
The pilot light went out and will not stay lit
After relighting it at the control knob — usually a thermocouple, which is a repair.
-
The ignition button will not reignite the burner
On a gas water heater.
-
The supply line coming off the unit is leaking
At or below the connection fitting.
Book soon if you notice:
-
The drain pan has water in it.
The unit is already weeping and the pan is catching it. This is an early warning, not a reason to wait.
-
Rumbling or popping sounds during heating cycles.
Sediment buildup at the tank base from Fort Collins hard water. A sign the unit needs flushing or is approaching failure.
-
Hot water runs out faster than it used to
Or takes longer to recover after use.
-
The unit is 10 or more years old and has never been flushed.
In Fort Collins hard water, an annual flush is maintenance, not optional.
My drain pan has water in it. Is that an emergency?
It means your water heater is already leaking — the pan is catching it before it reaches your floor. That is a good catch, but call today, not tomorrow. A weeping water heater can become a full tank failure without much warning. We assess the source on the same visit and tell you whether it is a repair or a unit that needs to come out.
We Try to Repair Your Water Heater Before We Recommend Replacing It
Most water heater problems are repairable. Here is how we decide.
Repair is usually right when:
-
The leak is at a supply line connection or the pressure relief valve. Often a fitting or valve replacement, not a new unit.
-
The thermocouple or thermopile has failed. The most common reason a pilot light will not stay lit. A straightforward part replacement in most cases.
-
A heating element has failed on an electric unit. We test both elements, identify the failed one, and replace it on the same visit.
-
A gas valve or igniter has failed on a tankless unit. Both are repairable without replacing the full unit.
-
The unit is under 10 years old and in otherwise sound condition with no internal corrosion.
Replacement is usually right when:
-
The tank body has corroded internally. Rust inside the tank cannot be repaired. If the water coming out is rusty or the tank itself is weeping from the body, it is time to replace.
-
The unit is 12 to 15 or more years old in Fort Collins hard water and failing repeatedly. At that age in these water conditions, a new unit is a better investment.
-
The repair cost exceeds half the cost of a comparable new unit. We give you both numbers and let you decide.
-
You want to upgrade from tank to tankless. We convert tank installs to on-demand tankless and handle the gas line or electrical upgrade the new unit requires. See our water heater installation page.
A plumber came out and said they don't service my water heater, only replace it. Is that normal?
No. Most water heater problems — including leaking fittings, a failed thermocouple, heating element failure, and igniter issues — are repairable without replacing the unit. Bluewave diagnoses first and recommends replacement only when repair is not cost-effective or not possible. We give you both options and both costs before you decide.
Water Heaters We Repair and Replace in Fort Collins
We service every common water heater type in Fort Collins homes and businesses.
-
Tank gas water heaters.
The most common unit in Fort Collins homes. Hard water sediment buildup is the leading cause of early failure here. We flush, repair, and replace, including Rheem, Bradford White, A.O. Smith, and State.
-
Tank electric water heaters.
Heating element failure is the most common repair on electric units. We test both elements, replace the failed one, and check the thermostat on the same visit.
-
Tankless gas water heaters.
Rinnai, Navien, Noritz, and Rheem tankless units need descaling in Fort Collins hard water every one to two years. We repair ignition failures, gas valve issues, and flow sensor problems, and perform descale service.
-
Tankless electric water heaters.
Less common in Fort Collins but fully serviceable. Element replacement and flow sensor repair are the most frequent calls.
-
Commercial water heaters.
We service tank and tankless commercial units for small businesses, restaurants, and rental property portfolios across Fort Collins.
Tankless Water Heater Flush and Descale Service in Fort Collins
Fort Collins hard water makes regular descaling more important here than in most Colorado cities. If you have a tankless water heater and have not had it descaled in the last two years, it is overdue.
-
Fort Collins water carries 8 to 14 grains per gallon of calcium and magnesium.
Inside a tankless heat exchanger, that mineral load builds into scale that reduces flow rate and heating efficiency within 12 to 18 months without treatment.
-
A descale service flushes the heat exchanger
With a descaling solution to dissolve mineral buildup and restore the unit to its original flow rate and efficiency.
-
Bluewave recommends descaling every one to two years
For Fort Collins tankless units. More frequently in homes without a water softener.
-
A maintenance visit also covers
The igniter, gas pressure and valve function, venting connections, and the cold water inlet filter screen.
How often does a tankless water heater need to be flushed in Fort Collins?
Every one to two years in most Fort Collins homes due to hard water from the Cache la Poudre watershed. At 8 to 14 grains per gallon, calcium scale builds inside the heat exchanger faster than in softer water cities. Without regular descaling, a tankless unit loses efficiency, flow rate drops, and the heat exchanger can fail well before its rated lifespan.

How much does water heater repair cost in Fort Collins?
Most repairs in Fort Collins run $150 to $600 depending on the part and the unit type. A thermocouple or heating element replacement is usually on the lower end. A gas valve replacement runs higher. We give you a written quote after diagnosing the unit. If replacement makes more sense than repair, we show you both costs at the same time so you can decide.
Why Fort Collins Water Heaters Wear Out Faster Than the Rated Lifespan
Fort Collins has water and climate conditions that put more stress on water heaters than the national average. Understanding why helps you know what to expect from your unit.
-
Hard water from the Cache la Poudre River accelerates sediment buildup.
Fort Collins municipal water carries 8 to 14 grains per gallon of dissolved calcium and magnesium from the Cache la Poudre and Horsetooth Reservoir. At this hardness level, sediment collects at the tank base 2 to 3 times faster than in soft water cities — shortening a rated 10 to 12 year lifespan to 6 to 9 years in homes without a water softener.
-
Garage-mounted water heaters face freeze and thaw stress.
Fort Collins homes frequently route water heaters through attached garages with minimal insulation. Supply line connections and pressure relief valve fittings experience repeated thermal expansion and contraction during Northern Colorado cold snaps, cracking fittings and loosening joints. This is why the garage is the most common location in our Fort Collins water heater calls.
-
Hard water scale reduces gas burner and electric element efficiency.
Calcium deposits on gas burner components and electric heating elements make the unit work harder to reach set temperature. The extra work accelerates wear and triggers failure earlier than the unit's rated lifespan would suggest.
-
Crawl space and attic supply line connections fail silently.
Some Fort Collins homes route supply lines through crawl spaces or attics. When a connection in one of these locations fails, the leak travels into living areas before the homeowner sees any sign at the unit itself.

Fort Collins Water Heater Questions
My water heater is leaking pretty bad. What should I do right now?
Turn off the cold water supply to the unit — the valve is on the cold inlet pipe at the top of the tank. For a gas unit, turn the gas valve to the pilot setting. For an electric unit, turn off the circuit breaker for the water heater. Then call (970) 997-1528. We assess it the same day and tell you whether it is a fitting repair or a unit that needs to come out. If water is spreading across the floor, this is an emergency plumbing situation.
The pilot light went out and I can't get it to reignite. Is that a repair?
Usually yes. A pilot that will not stay lit is most often a failed thermocouple or thermopile — a small component that senses the flame and keeps the gas valve open. Thermocouple replacement is a repair, not a full replacement. We diagnose on site and replace the failed component on the same visit in most cases.
I have no hot water at all. Is the water heater broken or could it be something simpler?
It depends on the unit type. On a gas water heater, no hot water usually means a pilot or gas valve issue. On an electric unit, it is typically a failed heating element or a tripped breaker. On a tankless unit, it may be an ignition failure or a blocked inlet filter. We diagnose first and tell you exactly what failed before recommending repair or replacement.
My water heater is 18 years old. Should I repair it or replace it?
At 18 years in Fort Collins hard water conditions, replacement is almost always the right answer. A tank water heater is rated for 10 to 12 years under average conditions. Fort Collins hard water from the Cache la Poudre shortens that to 6 to 9 years in homes without a water softener. At 18 years, the tank is likely corroding internally and a repair will not add much useful life.
Do you repair both gas and electric water heaters?
Yes. We service tank and tankless units running on natural gas, propane, and electric power. We repair all major brands including Rheem, Bradford White, A.O. Smith, State, Rinnai, Navien, and Noritz. If the unit can be repaired at a reasonable cost, we tell you that first.
Is emergency water heater repair available in Fort Collins?
Yes. A water heater leaking in the garage with water spreading across the floor is an emergency. We answer 24 hours a day, seven days a week including weekends. Call (970) 997-1528 and describe what is happening. For an active leak, turn off the cold water inlet valve at the top of the tank while you wait.
How often should a tank water heater be flushed in Fort Collins?
Once a year is the right interval for most Fort Collins homes. Hard water from the Cache la Poudre deposits sediment at the tank base faster than in soft water cities. Annual flushing clears the buildup before it insulates the burner, reduces efficiency, and accelerates failure. Homes without a water softener benefit most.
Can you install a tankless water heater to replace my old tank unit?
Yes. A tankless conversion involves removing the existing tank, installing a properly sized on-demand unit, and in most cases upgrading the gas line or electrical supply the new unit requires. We pull the City of Fort Collins or Larimer County permit, complete the installation, and test the unit before we leave. See our water heater installation page for details.
