No Hot Water
A tank weeping from its body rather than a fitting is done, so shut off its water and the gas or breaker feeding it and call.
When this becomes an emergency
- A shower that turns cold well before it used to.
- Knocking or rumbling from the tank during a heating cycle.
- A burner that lights and then drops out after a short run.
- Discolored water from hot taps only.
What a pro does
A plumber separates two failure patterns immediately. No heat at all sends attention to the burner, the thermostat or the elements. Heat that runs out early points at capacity, and on the Front Range that generally means sediment, since hard water drops minerals into the bottom of a tank with every cycle and that layer takes up volume the heater used to have. Altitude enters the picture on gas units. Air is thinner up here, combustion behaves differently than it does at sea level, and a heater that's set up or vented for lower elevation will burn poorly, short cycle or fail to hold a flame. Draft matters more than people expect. The plumber checks the venting and the combustion air supply as part of the job, particularly in a tight, well sealed home or a mechanical closet that's had other appliances added to it over the years. Electric units get their elements pulled and inspected, since scale coats them here and a scaled element runs hot and quits early. What the inspection shows decides between a service, a part, and a replacement.
