I have been a little concern with my hot water heater leaking as it has been a while since I last replaced it. My present hot water heater was manufactured in 1994, I didnt think it was that long ago. I guess I am due to swap it out. How long do they normally last.

10 to 12 years...more if you've changed the sacrificial anode...

You're doing exceptionally well with one at 19 years in service...I would change it just to be safe...they make a mess when they go...

My current WH was installed about 6-7 years ago, the previous WH lasted from 1971 until it was changed in 2006-2007, so it lasted about 35 years without any service

It will go 1 day into your next away from home vacation.....

I got a Whirlpool @ Lowes a few years ago for $301 w/ 12 year warranty. US made IIRC. Certainly won't break the bank for a little peace of mind. The previous one was over 15 years old AO Smith I believe.

OT:It is important to turn off your water, if you have that option, when you go on vacation.

I think it depends upon the quality of the glass lining. I believe there are different levels for how long the tank will last.

I know at one apt. complex they replaces the tank whenever anything in it goes wrong, like the element.

my parents had a Rheem with a 30yr warranty. It went 4 days past the 30years, my parents had the receipt still and Rheem took care of them.

The life of the water heater also depends on the location of the country because of the acidity of the water that goes into it. My sister and BIL in New Mexico have some rental property and they consider themselves lucky if they get 7 years out of one.

Here our electric company will give you a new hot water heater free of charge up to 80 gallons every 7 years.

Gas company too will give you a free gas water heater if you change from an electric one to natural gas.

You may want to check with them and see what specials they offer.

IMHO it depends on (a) how much hot water you use from your tank; and (b) how long the warranty (directly related to the anode rods and also tank liner (to a lesser extent).

shortly after I moved into our house, our AOSmith "skinny" 40Gal gas tank blew (just shy of 4 yrs of service for a 6yr tank). Apparently, previous house owner has 4 daughters + wifey that used hot water on an hourly basis (yeah, wash hair, body scrub, etc.)....

I've just replaced it with a full-sized GeeEee(Rheem) with 12yr warranty ....lifetime replacement by Home Deport.

Depends on where it's leaking. Some times the pressure relief valve will leak. But if it leaks out the bottom then it's time to buy a new one.

I have a water softener and am on fairly hard well water. I take the anodes out because it reacts with the water and stinks. But I get about 20 years to a gas one.

Adding extra insulation also keeps the cycles down.

Very true, I just replaced our water heater last month and it was 7 years old. The plumber said it went 3 years beyond most in our town due to the water quality, and we have a water softener as do most people here.

My friend about a mile way in the same town here has replaced three water heaters in the past 15 years.
