Leaking or pooling water
on the top around the water connections and/or under or near the heater. Never ignore any leaks coming from your water heater. Calling in a certified plumber can prevent major damage/loss to your home.
Rust stains
on laundry or in showers or sinks may be evidence of rust buildup in the water heater. If rust begins to show on the outside of your water heater, that is a sign that it will soon begin to break down and leak.
Rusty water
comes out of the taps. Depending on the age of the water heater - this could just be a sign that it may need some maintenance and repairs.
Slow hot water recovery time
it takes longer to heat up water or the water doesn’t get as hot even though heat settings haven’t changed. This could be a sign that there is a large build up of sediment, having your water heater flushed annually can help flush out build up and keep your water heater lasting longer.
Bubbling or boiling noises
in your tank as water heats up. If your water heater is making noise, it is time for it to be replaced.
Life expectancy
