& Heating Tips
Most water heater problems are a repair, not a replacement, as long as the tank itself is under about 8 years old and hasn't started leaking. A failed thermocouple, a bad heating element, a stuck valve, or sediment buildup are all common, fixable issues on a tank that's otherwise in good shape. The trick is telling the difference between a part that failed and a tank that's failing. Here's how to sort through the most common problems we see, and what each one usually means.
A pilot light that won't stay lit is almost always one of three things: a failing thermocouple, a draft affecting the pilot flame, or a dirty pilot orifice. The thermocouple is the most common cause on tanks over 5 years old. Here's what each cause looks like and how to tell them apart.
