When your water heater starts to malfunction, the signs are often subtle at first. They can suddenly become urgent. For homeowners in Bellingham, WA, relying on Marr's Heating, AC, Plumbing and Electrical ensures prompt water heater services. Knowing the signs of a failing water heater is essential so you can take the necessary action.
Aging Water Heater
Most traditional storage tank water heaters have a lifespan of 8 to 12 years. Tankless versions can last 20 years or more with proper care. The risk of failure increases with each year beyond the typical lifespan.
If yours is near or past the threshold, start planning for an inspection or replacement. It’s always best to act proactively rather than to wait for a complete failure.
Strange Noises From the Tank
Popping, rumbling, and banging sounds usually indicate problems. Sediment buildup can make these noises. As water heats, trapped sediment begins to overheat, making the heating function less efficient and wearing down components.
Traditional tank water heaters need yearly maintenance to flush sediment. Neglect can lead to significant sediment buildup that can weaken the tank through corrosion and cause premature failure.
Temperature Issues & Inconsistent Hot Water
When water heaters begin to fail, they will no longer heat water as effectively. The water may not be as warm, or the unit may take longer to heat. Temperature issues can stem from failing heating elements or problems with the burner.
Water that gets too hot, over 120 degrees, is also a bad sign. Not only is it a safety issue, but it may also indicate a failing thermostat.
Fluctuations in temperature during showers indicate a problem with the water heater’s heating cycle management. Never ignore temperature problems, as they can worsen rapidly in a failing water heater.
Discolored or Smelly Water
Rusty or brown water from your hot faucets often comes from tank corrosion. The anode rods protecting the tank have likely become depleted. Continuing to operate a unit with a depleted anode rod can lead to tank corrosion and an increased risk of leaks.
You may have a metallic taste or an odd smell, such as rotten eggs or sulfur. These signs indicate corrosion or bacterial growth inside the tank. If the odors persist despite flushing or cleaning, you may need to consider replacing your water heater.
Water Leaks & Moisture
Even minor leaks are warnings. Water pooling around the base or moisture on the seams, connections, or valves means parts are failing.
The tank itself can become so corroded that it begins leaking at the most vulnerable areas, especially around the joints. Once the tank wall becomes compromised, replacement is the only safe option.
Pressure Relief Valve Problems
The temperature & pressure relief valve is an essential safety device. If it leaks or fails to discharge properly when tested, there is a significant problem.
The valve opens if the pressure or temperature rises too high. If the valve becomes stuck in either the closed or open position or if the discharge pipe clogs, it presents a dangerous situation. Our experts at Marr's Heating, AC, Plumbing and Electrical can test and replace faulty valves for your family’s safety.
Rising Energy or Fuel Costs
As the water heater weakens due to sediment buildup or failing parts, it will require more energy or fuel to perform the same job as before. You will notice this inefficiency on your utility bills.
If you have a pilot light or burner unit, soot buildup or incomplete combustion can also reduce efficiency. When efficiency begins dropping, it is wise to consider a replacement.
Frequent Repairs
If you’ve already had multiple repair calls in a short span, the cost of continued repairs may exceed the cost of replacement. Frequent repairs also indicate the heater is on its last legs. We’ve seen many cases where homeowners spend more money repairing old water heaters rather than installing a new one.
Repair bills add up over time. If you are incurring multiple repair costs within a year, it’s time to consider installing a new, energy-efficient unit. A new water heater can save you money and aggravation.
What You Should Do If You Notice Problems
If you notice signs of immediate problems, call a professional for a water heater inspection to determine if your unit is better repaired or replaced. We can help you compare costs and remaining lifespan. We can also try to work within your budget for replacement options.
If you have a traditional water heater, it needs a flush every year. Homeowners with hard water should schedule flushes more frequently, usually every six months. You should also monitor your water quality. In homes with hard water, buildup can happen fast, leading to water heater malfunctions. Homeowners in Bellingham sometimes install water softeners to combat hard water and prevent their water heaters from failing prematurely.
Choosing a Water Heater Replacement
Once your water heater reaches the end of its lifespan, you’ll need to decide on a replacement. Today’s units are more efficient and can save you up to $170 a year, according to the US Department of Energy.
Homeowners frequently install tankless water heaters when their old standard units stop working. Tankless water heaters require less space, provide hot water on demand, and operate more efficiently. They also last longer, up to 20 years or more, with proper care.
There are several factors to consider when deciding on a new water heater installation in Bellingham.
Type of Water Heater
Beyond tanked or tankless, you will also need to decide on the fuel source. There are both gas and electric models, depending on your preferences and fuel availability.
Capacity & Household Size
You will also need to determine the capacity to meet your family’s needs. We can help you choose the best size for your home’s occupants. Consider the following:
- 30 to 40 gallons: 1-2 people
- 40 to 50 gallons: 2-3 people
- 50 to 80 gallons: 3-5 people
Larger families may need bigger tanks or a tankless water heater. Some residential tank water heaters go up to 120 gallons or more.
Energy Efficiency
Look for the Energy Factor or Uniform Energy Factor rating when considering a water heater. The higher the number, the more efficient the unit.
Consider models with the ENERGY STAR certification, which enables you to save money over the unit’s lifetime. Although more efficient water heaters may cost more upfront, they compensate for the added expenses with long-term savings.
Don’t Let Water Heater Failure Catch You by Surprise
Your water heater does a lot of work behind the scenes. Although out of sight, out of mind, don’t wait until something goes wrong to check your water heater. Look for warning signs such as leaks, unusual noise, signs of old age, and inconsistent water temperatures.
