Water heaters are one of the hardest-working appliances in your home, heating and storing hot water for your use. They’re built to last, but if yours starts leaking or stops producing hot water, your water heater may need repairs or service.
Typically, a water heater comes with a warranty anywhere from 5-15 years on parts. For this reason, if you start experiencing issues, you should find the model & serial numbers of your water heater to find out if it is still under warranty. Our service technicians are local to Mercer Island and are familiar with most regional heater applications, brands and models.
It’s important to note, if your water heater is more than 10 years old, it’s probably nearing its last legs. Considering the cost of labor, it might be cheaper in the long run to just replace the unit.
In Mercer Island, common repairs and maintenance our technicians experience with residential water heaters include:
- Replace the thermocouple – Sometimes a fix is as simple as one small part. This is often the case when a water heater isn’t heating water; typically it just needs a replacement thermocouple, which allows the heater to take in gas.
- Replace the anode rod – Over time, the minerals in your water and pressure in your tank will cause corrosion of your water heater. Anode rods prevent tank corrosion because they attract the corrosive elements, keeping them away from the storage tank. The installation of dual anode rods, or a replacement can extend the life of your heater.
- Pilot light – This simple mechanism is also responsible for lots of water heater repairs. Sometimes the light can simply go out and just needs to be re-lit. Other times, the assembly may have failed, in which case it would need to be replaced.
- Drain storage tank – Some newer water heaters have self-cleaning tanks, however, older ones need to be manually drained to prevent a sediment build-up. If you fail to drain the sediment, eventually the mineral deposits will collect and shorten the useful life of your water heater.
