Maintaining the water heater in your Ann Arbor, MI home is important when it comes to efficiency, safety, and longevity. When you work with Benjamin Franklin Plumbing® of Ann Arbor, you’re not just maintaining performance — you’re protecting your investment. Whether you have a traditional tank-style water heater or a tankless model, we recommend scheduling professional maintenance at least once a year to prevent costly repairs and extend the life of your system.
Different Types of Water Heaters
There are several types of water heaters available. This includes a tank-style heater, which stores a large volume of water and maintains its temperature until it’s needed. Tankless water heaters, also known as on-demand systems, have grown in popularity in recent years. They provide hot water as needed without the need for a storage tank. Some homes benefit from a heat pump water heater, which transfers heat from the air to the water using electricity, making them highly efficient. Solar water heaters also exist, using energy from the sun to heat your water, though they are more common in sunny southern states.
Routine Hot Water Heater Maintenance Tasks
Several tasks should be performed annually by a professional. Routine service allows us to catch early warning signs of wear or failure, often preventing more expensive repairs or a complete breakdown.
Draining and Flushing Your Tank
Sediment and mineral buildup from hard water is common inside tank-style heaters. This buildup reduces your system’s efficiency and the space available for hot water. We recommend draining and flushing your tank once a year, especially in areas like Ann Arbor with moderately hard water. This process helps protect your heater and restore efficiency.
Inspection of the Anode Rod
Tank water heaters contain a sacrificial anode rod that helps prevent internal corrosion. Rather than attracting sediment, the anode rod draws in corrosive elements like oxygen and chlorides. We’ll inspect this component as part of your routine service. If it’s heavily corroded, replacing it can greatly extend your tank’s life.
Temperature and Pressure Relief Valve
The temperature and pressure relief (TPR) valve is a key safety feature. It releases excess pressure if water gets too hot or if internal pressure builds up to dangerous levels. We’ll test this valve to make sure it opens correctly and seals tightly. If there’s a leak or the valve doesn’t open under pressure, it should be replaced right away.
Thermostat Inspection and Adjustment
We recommend setting your water heater thermostat to 120°F, which balances safety and energy efficiency. This temperature helps prevent scalding and saves on utility costs. If you're not getting enough hot water or if water temperatures vary, we can help assess whether a thermostat adjustment or repair is needed.
Burner or Heating Element Maintenance
We’ll inspect and clean the burner or heating elements during your annual visit. These parts often need replacement before your unit reaches the end of its lifespan, especially in homes with hard water. While gas burners may last longer with care, electric heating elements may need replacement every 3–5 years, depending on usage and mineral buildup.
Inspecting Your Heater for Leaks
We’ll check around your unit for moisture or active leaks. Even a small leak can lead to water damage, microbial growth, and equipment failure. If we catch the issue early, we can help you avoid larger problems.
Checking for Corrosion
Exterior rust is a red flag — it often means internal components are also corroded. This is a common sign that your water heater is nearing the end of its lifespan. If we spot corrosion, we’ll walk you through replacement options.
Tankless Water Heater Maintenance
Tankless systems don’t store hot water, but they still require maintenance to stay efficient. In areas with hard water, like Ann Arbor, buildup from calcium and magnesium can occur faster, making annual maintenance critical.
Flushing and Descaling Your Unit
To prevent scale buildup and maintain peak performance, we flush tankless systems annually with a descaling solution. Homes with very hard water may need this service every 6 months.
Changing or Cleaning Your Filter
Most tankless water heaters include a small inlet water filter that protects the internal components from sediment, not your water supply. We’ll clean or replace this filter, and if your system includes an air intake filter, we’ll make sure it’s clear and functioning properly.
Pressure Relief Valve Inspection
Just like with tank models, tankless systems have a pressure relief valve that must function properly. If the valve leaks, won’t open, or is damaged, it should be replaced right away.
Checking for Leaks and Other Issues
We’ll inspect your tankless system for signs of corrosion, loose fittings, water leaks, or gas issues. If your system has a digital display, we’ll also check for error codes or performance warnings. Common issues we look for include fluctuating water temperatures, reduced water flow, mineral scale, and unusual noises.
What Are the Signs That Indicate the Need for Maintenance or Repairs?
