Water Heater Repair: Common Problems and When to Call

 

Most water heater problems fall into recognizable patterns. Knowing which symptoms indicate a repairable issue versus a system that needs replacement helps you make a clear decision before a technician arrives.

​

• No hot water: likely a failed heating element on an electric unit, or a pilot light or igniter issue on a gas unit. Usually repairable in a single visit.

• Inconsistent water temperature: often a thermostat failure or a sediment layer insulating the heating element from the water. Addressable with a thermostat swap or a tank flush.

• Discolored or rust-colored hot water: points to a failing anode rod or a corroding tank interior. A new anode rod extends tank life when caught early; tank interior corrosion means replacement.

• Rumbling or popping during heating cycles: sediment buildup at the base of the tank. A professional flush helps, but heavily sediment-loaded tanks in hard water areas are often near end of life.

• Water pooling at the base of the unit: a failed pressure relief valve, a leaking drain valve, or a compromised tank. Tank leaks cannot be repaired and require replacement.

 

Our technicians carry common repair parts and can diagnose most water heater problems on the first visit.

 

Repair vs. Replace: How to Decide

 

The decision between repair and replacement depends on the age of the unit, the type of failure, and the cost comparison between fixing it and installing a more efficient system.

​

• Under 6 years old: repair is almost always the right call unless the tank has developed a structural failure.

• 6 to 10 years old: evaluate repair cost against replacement cost. A repair that exceeds half the cost of a new unit on a tank approaching 10 years is difficult to justify.

• Over 10 years old: replacement is usually the better long-term investment. Most gas tank water heaters in the Des Moines metro have a realistic service life of 8 to 12 years.

 

Des Moines Water Works supplies water at approximately 157 ppm (9 grains per gallon), which is in the hard to very hard range. Hard water accelerates anode rod depletion and sediment buildup, shortening tank lifespan compared to national averages. If you are unsure how old your water heater is, the serial number on the label encodes the manufacture date for most brands.

 

Water Heater Installation in Des Moines and Urbandale

 

When replacing a water heater, the right system for your household matters as much as the installation itself. The three primary types each have different strengths for Des Moines-area homes.

 

Tank Water Heaters

 

Traditional tank water heaters store and maintain a fixed volume of hot water, typically 40 to 80 gallons. They are the most common choice for residential installation and the most straightforward to replace. Most standard tank replacements are completed in 2 to 3 hours.

 

One practical consideration for Polk County homeowners: federal efficiency standards updated in 2015 (NAECA) require tank water heaters above 55 gallons to meet higher efficiency thresholds, resulting in physically larger units. Replacing a large tank in a tight mechanical closet in an older Ankeny or Urbandale home may require a reconfigured space. We assess clearance and venting requirements during the quote process.

 

Tankless Water Heaters

 

Tankless systems heat water on demand, eliminating standby heat loss and delivering continuous hot water as long as the gas or electric supply meets the load. They are well suited to households with high hot water demand and to homeowners focused on long-term energy efficiency.

 

Installation requires confirmed gas line capacity (for gas units) or electrical panel capacity (for electric units), plus proper venting for combustion exhaust. Retrofitting a tankless unit into an older Des Moines or Urbandale home sometimes involves gas line upgrades or venting modifications. We evaluate all of this during the quoting process so there are no installation-day surprises.

 

Tankless units typically last 15 to 20 years with proper maintenance. In Des Moines, annual descaling is important to address scale accumulation from the hard water supply.

 

Heat Pump Water Heaters

 

Heat pump water heaters extract heat from the surrounding air and transfer it to the water, making them 2 to 3 times more energy efficient than standard electric resistance units. They are a strong fit for households with electric heat and for homeowners taking advantage of available utility rebates.

 

An important consideration for Iowa: heat pump water heaters work most efficiently in conditioned spaces and perform poorly in unheated garages or utility rooms during winter. Most Urbandale and Ankeny installations go into finished basements, where ambient temperatures stay consistent year-round. We assess your mechanical room before recommending this option.

 

Hard Water and Your Water Heater in Des Moines

 

Water hardness at 157 ppm from Des Moines Water Works creates two specific maintenance challenges for water heaters. First, it depletes the sacrificial anode rod inside tank units faster than in soft water areas. The anode rod is the component that protects the tank interior from corrosion. Once depleted, the tank itself begins corroding from the inside out. Replacing the anode rod every 3 to 5 years significantly extends tank life.

 

Second, calcium and magnesium deposits accumulate at the base of the tank and on heating elements over time. Annual flushing removes loose sediment. Hardened deposits in a neglected tank generally cannot be fully removed and reduce both efficiency and service life. Pairing a tank water heater with a whole-home water softener addresses the root cause rather than just the symptom. See our water quality services for softener installation options.

Frequently Asked Questions

 

How much does water heater replacement cost in Des Moines?

 

Tank water heater replacements in the Des Moines metro typically run $900 to $1,800 depending on unit size, fuel type, and any venting or space modifications needed. Tankless systems typically run $1,500 to $3,500 installed. 72 Degrees provides upfront pricing before any work begins. See our financing options for qualified installations.

 

Can you replace a water heater the same day in Urbandale or Ankeny?

 

In most cases, yes. We stock common Bradford White tank sizes and can complete most standard replacements within a few hours of the technician arriving. Call (515) 965-7272 to confirm same-day availability for your location.

 

How long do water heaters last in Des Moines?

 

Tank water heaters in the Des Moines area typically last 8 to 12 years. Des Moines's hard water supply (157 ppm / 9 grains per gallon) accelerates sediment buildup and anode rod depletion, which can shorten that range for units that are not maintained. Tankless units generally last 15 to 20 years with annual descaling.

 

What are the signs my water heater needs to be replaced?

 

Key signs include water that takes significantly longer to heat than before, rust-colored or metallic-tasting hot water, audible rumbling or popping during heating cycles, water pooling at the base of the unit, or a unit that is more than 10 years old and requiring its second or third repair.

 

Is a tankless water heater a good choice for an Ankeny or Urbandale home?

 

Tankless units are a good fit for households with high hot water demand where the existing gas line and venting can support the installation without major modification. We assess both before quoting so you have an accurate picture of total installed cost. See the installation section above for a full comparison of system types.

 

Does hard water affect my water heater?

 

Yes, significantly. At 157 ppm, Des Moines Water Works supply is classified as hard to very hard. The mineral content accelerates anode rod depletion in tank units and causes scale buildup in tankless heat exchangers. Annual descaling and anode rod replacement extend service life considerably. A water softener addresses the root cause. See our water quality services.

 

Do you service all water heater brands?

 

Yes. Our technicians service all major residential water heater brands and can source parts for most current models. We install Bradford White equipment as our primary supply for new installations and replacements.

Does 72 Degrees offer financing for water heater replacement?

Yes. Financing options are available for qualified installations. See our financing page or ask your technician at the time of your appointment.
