FAQ
Lifespan depends on water quality, usage and maintenance. Regular flushing helps, and we can assess your tank’s condition during a visit.
If the tank itself is leaking, replacement is usually needed. Problems with parts like elements, thermostats or valves can often be repaired. We will explain both options clearly.
Rumbling or popping is usually caused by sediment buildup at the bottom of the tank. Flushing the tank often helps.
Turn off the water supply to the heater and switch off the power or gas if it is safe to do so, then call us right away.
Once a year is a good rule of thumb, or more often if you have hard water.
