Homes across Erlanger, Florence, and the older neighborhoods throughout Boone, Campbell, and Kenton counties put water heaters through more than most. The limestone-fed water supply that runs through this region is hard on tank interiors, heating elements, and anode rods. Components are worn down faster than homeowners in softer-water markets typically expect. Add in the aging mid-century housing stock common throughout Erlanger, Covington, and Newport where original water heater installations have been in place for decades, and repair calls here tend to come earlier and more often than the national averages suggest.

Arlinghaus has been based in Erlanger for years, and water heater repair is one of our most frequent calls from homeowners across Northern Kentucky. Whether you’ve woken up to a cold shower in a Florence ranch home, found water on the utility room floor of an older Covington craftsman, or your tank has started making noises that weren’t there last winter, our licensed plumbers are ready to respond. We service gas, electric, and tankless water heaters of all major brands, with 24/7 emergency availability and same-day service for urgent situations.

Emergency Water Heater Repair, Available 24/7

A water heater failure doesn’t just mean cold showers; a leaking tank or a failed pressure relief valve can cause serious water damage in a short period of time. Arlinghaus responds to emergency water heater calls throughout Erlanger, Florence, and Northern Kentucky 24 hours a day, 7 days a week, including weekends and holidays. Same-day service is available for urgent situations.

If water is actively leaking from your unit, shut off the cold water supply valve at the top of the tank and call us immediately.

Signs Your Water Heater Needs Repair

Water heaters don’t usually fail without warning. These are the signs NKY homeowners most commonly report before calling us:

  • No hot water or water that won’t get hot enough – causes range from a tripped breaker or failed heating element in electric units to a pilot light issue or failed thermocouple in gas units
  • Running out of hot water faster than usual – often a sign of sediment buildup reducing the effective capacity of the tank; particularly common in NKY given the region’s hard water supply
  • Rusty, discolored, or cloudy water from hot taps – indicates internal tank corrosion or a deteriorating anode rod requiring prompt attention
  • Popping, rumbling, or banging noises – caused by sediment accumulation on the tank floor; hard water from NKY’s limestone aquifer accelerates this buildup significantly compared to softer-water markets
  • Pilot light that won’t stay lit – specific to gas water heaters; usually a thermocouple or gas control valve issue
  • Water leaking from around the base or from valves – the source of the leak determines the repair; a T&P valve drip is different from a supply line issue or tank corrosion
  • Rotten egg or sulfur smell from hot water – often caused by a failing anode rod
  • Rising energy bills without explanation – a water heater working harder than it should due to sediment or a failing component will show up in monthly utility costs before it becomes a visible problem

Our service tech was knowledgeable and took the time to show us what was going on with our AC unit. I was kept up to date with texts throughout the process before he arrived. He took the time to ask if we had any questions. Would highly recommend Arlinghaus!
Arlinghaus was great to get someone to my home immediately as I was dealing with a burst pipe. Mike Thomas was so kind and professional, and thorough in his work. The rates were very reasonable for the wonderful service provided. I certainly will be calling them back if I have any future issues (though I hope I don't!)
I contacted Arlinghaus to have our hot water heater replaced and water softener system installed. The two techs that came out and worked on our project, Derek Mullins and Claude Jones, were excellent! Super nice guys, kept us informed, and did a fantastic job on our house. I appreciate their professional manner and knowledge on this job and I would recommend them for future work. Thank you guys for restoring the hot water in our house and for installing our new water softener, we are so happy for these upgrades!!

Common Water Heater Repairs We Perform

Arlinghaus repairs gas, electric, and tankless water heaters throughout Northern Kentucky. Here’s what our licensed plumbers most commonly address:

  • Heating element replacement – the most common electric water heater repair; upper and lower elements fail independently and each produces different symptoms; typically a same-day repair
  • Thermocouple and pilot light repair – for gas units where the pilot light won’t stay lit; a failed thermocouple is the most frequent culprit
  • Thermostat calibration and replacement – both gas and electric units have thermostats that can fail or drift; incorrect temperature output is the primary symptom
  • T&P valve replacement – a dripping or stuck temperature and pressure relief valve needs prompt attention; scale buildup from NKY’s hard water is a common cause of valve seat failure
  • Anode rod replacement – NKY’s hard water at 120–150 mg/L of mineral hardness consumes anode rods faster than the national average, shortening their typical replacement interval
  • Sediment flush – mineral sediment from the limestone aquifer accumulates on the tank floor over time, reducing efficiency and causing the rumbling noises common in Erlanger and Florence homes
  • Gas control valve replacement – controls gas flow to the burner; failure produces no heat or erratic temperature output

Gas, Electric & Tankless Water Heater Repair

Gas and electric water heaters fail in different ways and require different repair approaches:

Gas water heater repair covers pilot light and ignition issues, thermocouple and gas valve failures, venting problems, and burner assembly repairs. Gas work requires a licensed plumber and Arlinghaus is licensed for gas line and appliance work throughout Kentucky, Ohio, and Indiana.

Electric water heater repair covers heating element testing and replacement, thermostat issues, and circuit breaker faults. If resetting the breaker doesn’t restore hot water, the problem is internal and needs a licensed plumber.

Tankless water heater repair varies significantly by brand and model. Arlinghaus services tankless units from all major manufacturers and carries the diagnostic equipment to read error codes and pinpoint failures accurately.

Why NKY’s Hard Water Is Hard on Water Heaters

The water throughout Northern Kentucky carries high mineral content from the limestone aquifer feeding municipal water across Boone, Kenton, and Campbell counties. At 120–150 mg/L of calcium and magnesium hardness, NKY water accelerates the problems that drive water heater repair calls here more than in most other markets:

  • Sediment accumulates faster on the tank floor, causing efficiency loss and the rumbling noises common in Erlanger and Florence homes
  • Anode rods are consumed more quickly, shortening the replacement interval needed to maintain tank protection 
  • Heating elements in electric units scale up faster, leading to earlier failure. T&P valve seats accumulate scale that causes dripping or sticking

A whole-home water softener reduces the mineral load that drives all of these issues. It’s worth discussing alongside any water heater repair where sediment or anode rod problems have been recurring.
