Water heater warranties - 6, 9 or 12 years?


Our city water causes sediment to build up in our residential water heater. A water heater will only last me 6-7 years. I do not want to install a water softener. Does it matter if I buy a W.H. with a 6, 9 or 12 year warranty? Will they all build up sediment at about the same rate? Advise please.
Thank you.

You should flush the water heater generally, twice a year. If your water has a lot of sediment, 3-4 times a year. That will help extend the heater life. Consumers magazine says there is a difference in longer warranty tanks, other that the warranty, but i am told otherwise by professionals that should know.

To flush, run a hose from the drain spigot at the bottom(not the T&P valve at the top) to a sink or bucket, turn the thermostat down, and open the valve. Flush until the water runs clear. If nothing comes out, sediment is clogging the valve and a coat hanger or similar may get things flowing. Caution-hot water.

When I purchased my last HWH with 12 year warranty the difference from what what I can remember was the insulation under the metal jacket was thicker.
I can not remember if there was any other differences.

Thank you.
The six year warranty tanks I install are the very same as the ten year tanks, only more expensive (for the four year warranty extention). I agree, if you've lots of sediment, flush bi-annually or three times per year.

Sediment is a problem in my area also, more so on City Water than most home's well water, go figure. One thing I highly recommend to a homeowner when I install a new water heater is to allow me to change the drain valve at the bottom to either a gate valve or ball valve. Those plastic drain valves which come with a water heater just do not allow enough water to pass through for a good "flushing" to me. Once a gate or ball valve is installed, with an adapter for a garden hose to attach to it, a good "full flow" is established. And--I always place a pipe plug in the valve when not in use. Just me in my older age, David

I'm using this style heater lifetime warranty not to leak for the original owner.

http://www.marathonheaters.com/

The only gripe I have is there is no off peak rates here , it would be ideal for this type.

I have a whole house sediment filter also (well), cheap insurance for everything downstream IMO.

When I lived in town I think it was the city's old rusty pipes that spewed crud my way, should have run a filter there also.

i tell customers to drain 5-10 gallons of water every month from water heater.another thing you could do is install a whole house filter system where your water enters house,you can usuall buy one for around $50 at menards i install lots of these especially on houses with well water,water softeners just dump lots of salt in water to hide problem!
