Modern water heaters are sophisticated appliances that run efficiently and deliver hot water consistently. When something goes wrong, it’s often not a task for the average homeowner. Instead, it requires the knowledge and tools of an experienced plumber.
Ruling Out Fuel- and Power-Related Issues
Most water heaters, including fuel-burning models, require electricity. A common problem is tripped circuit breakers. Frequent tripping is often due to a worn breaker that needs replacement. If it’s not the breaker, it could be a bad wire or connection causing the surge.
Pilot light issues are often caused by carbon buildup or an incorrect fuel-air mixture. Pilot lights are uncommon nowadays as most water heaters have electronic ignition systems. When these systems malfunction, it’s often due to a sensor or valve that needs calibration or replacement.
Flushing the Tank and Inspecting the Anode Rod
Most households get their hot water from traditional storage-based water heaters. They store and heat water in a tank that’s prone to the accumulation of rust, limescale and other sediment. A buildup can cause many issues related to pressure and temperature. Often, the fix is to flush the tank to remove the sediment.
Water heaters with tanks also contain sacrificial anode rods. These components attract sediment through electrolysis and eventually corrode to the point of failure. A plumber will inspect the rod and, if it’s failed, cut a new rod to size and replace the old one.
If there is a rotten egg smell coming from your water heater, a plumber may have to flush it twice. After the first time, the plumber will fill it with a diluted bleach mixture. After letting that mixture sit for a period, the plumber can flush the system again and refill it.
Descaling the System
While on-demand water heaters don’t have tanks, they’re still susceptible to limescale. If it’s accumulated, a plumber will remove the buildup in the system with a recirculating pump and a cleaning mixture. It may also be necessary to swap out any air and water filters.
Checking and Calibrating the Thermostat
All water heaters have at least one thermostat, and most electric models have two. Thermostats are a common cause of problems because they directly control the water heating. Using specialized tools, a plumber can test thermostats to ensure the readings are correct. If not, your plumber may need to calibrate or replace the thermostat.
Inspecting Heating Elements and Heat Exchangers
Components coated in scale may require cleaning as they act like an insulator and reduce the system’s efficiency. If an element or exchanger is cracked or otherwise broken, your plumber must replace the damaged part with a new one.
