Frequently Asked Water Heater Questions
No Hot Water
When you go to take a shower or use a hot water faucet and there is no hot water, it could mean one of two things. Either another household member used all the water while doing laundry, during their shower, or the pilot light on your water heater had burned out.
When the thermostat in the water heater detects that the water in the tank is not at the set temperature, it will try and activate the burner. When the pilot light goes out, the burner is not able to activate and heat the water. This is the cause of not having hot water.
When a pilot light goes out, the first thing to do is try to re-light it. To learn how to light a pilot light, watch our video How to Light a Pilot Light.

Sediment
As a water heater ages, it produces less and less hot water.
This is usually caused by sediment buildup inside the tank. The amount of heated water your water heater can produce will be attenuated as sediment gets collected. If sediment is a problem, the water heater will usually be noisy or make loud rumbling disturbances.
Most of the time, the sediment can be flushed out of the water heater to resolve the issue, but this is not always the case because the sediment particles have grown, in which case replacing the water heater may be the only option.
Malfunctioning Parts
A faulty or defective part can also be the source of insufficient hot water. A part can wear out over time or due to a manufacturing error, but they are usually easily replaceable to get your water heater working at peak efficiency again.

Leaking Water Heater
The most important thing to remember when your water heater begins to leak is to locate the source of the leak. Depending on where the leak is coming from, your water heater may be repairable.
Turn off the gas or electricity, as well as the water to the unit if the leaking water heater is causing damage to the surrounding area. Watch our video How to Turn Off a Leaking Water Heater for assistance in turning off your tank.
The leak should be repairable if it is caused by a pipe or component connected to the tank. If, on the other hand, the water heater is leaking from the tank itself, the inner tank has almost certainly ruptured and the water heater will need to be replaced.
If your water heater displays any of the above symptoms, it is time to have it inspected by a licensed professional. Even if the symptom appears to be minor, it is best to have it checked out; the inspection may save you money in the long run.
Noisy Water Heater
A rumbling noise in your water heater could mean a buildup of sediment at the bottom of the tank, which happens if it has not been regularly drained. The sound is from the water escaping the sediment as it’s heated. This will result in losing some heat to the sediment, making it less efficient, as well as overheating the bottom of the tank and shortening its lifespan. It can be solved by flushing your water heater, but if the sediment has enough time to solidify, it won’t come out and the only solution would be to replace the water heater.
A high pitched noise can be faulty pressure control and should be addressed immediately. Water heaters have a temperature and pressure relief safety valve, designed to open and release water when either the temperature becomes too high or and excess amount of pressure builds up inside the tank. Unsolved, this can lead to leaks and cracks in the plumbing system, and even a burst water heater.
