We bought a property and redoing the garage. The previous owner installed a 38 gallon tank (property is about 1350 sq ft) manufactured in 2010. The previous one apparently had a leak which caused the water heater stand to grow black mold. I'm having to replace the stand and repair areas surrounding it, and I'm paying the plumber $300 to take the water heater down and install it again while I do this. We are also finishing out the garage, spending a good amount of money on drywall and electrician with EV charger, etc.

Now I'm thinking... should I spent an extra $600 to get a new, 50 gallon tank to replace a 7 year old, working water heater? I live in So California and have hard water. We haven't moved in yet and have money going out on other things. They say the life expectancy of a water heater is 8-12 years old... and the plumber says just keep the old one and replace it when it dies. It's hard making a decision to replace something that's working fine.

Anyone would like to chime in?

Not because it is 7 years old... NO.

That depends on where you are... water conditions, filtering, maintenance etc. LINK
And to a lesser degree on the heater itself (anode rods etc)
In many places WH life is well over 20 years.

btw... who is this "they" that you credit so highly?

I tend to agree.

But I would poke around to see what filtering, maintenance, etc your neighbors are doing.

WH life only 8~12 years? Who says that? Of the 4 homes I've owned, only one had something newer than 15 years (current), though I did have to replace the WH in my first house... it was 38 years old and original to the home.

You can do a couple things, use a catch-basin under the heater with a water sensor so you know the moment it starts to leak, drain the heater yearly to flush out sediment and maybe look into filtering/treating the water.

I certainly wouldn't replace what I consider to be a fairly new water heater... heck, even the guy who could make a few more bucks off you if you did, is telling you not to.

Default Depends on what your real motivation is ...

As other have said, replacement before failure is generally NOT a good idea from a purely out of pocket "budget" standpoint.

That said, even though a 1350 sg ft home is DARNED SMALL these days the fact is a 38 gallon wh is pathetically SMALL -- one good load of laundry or cycle of the dishwasher and you will be taking a COLD bath!

You won't see a huge difference with 12 more gallons of capacity, but there are other options. If you are already committed spending money to "fancy up" your garage AND are planning on having a EV you almost certainly should consider a HEAT PUMP wh. In SoCal a heat pump type WH will be able to COOL YOUR GARAGE and essentially use the other wise wasted warmth of your garage to heat water ON THE CHEAP.

The DOE has a site that explains what variables you need to determine a payback period for this decision -- https://energy.gov/energysaver/estim...-water-heaters

give it a good flush and check the anode rod. I wouldn't worry about it. Mine's over 10 years old and I have no plans to replace it. I have an AO Smith brand installed by a local company though, not a lowes special. Properly flushed with the anode rod replaced when needed, a water heater, particularly a gas one, can last 20 years.

Mine is 12 years old - installed by builder. It's never been flushed �� I guess some people said not to flush because after this long, I may start a leak by flushing. I don't use much hot water so will just let it ride a few more years.

First of all, water heaters typically last a long more than 8-12 years. So replacing the current WH is probably unnecessary.

That said, since you're already spending a lot of money, and extra $600 is probably a drop in the bucket, and a small price to pay for having everything new.

Is this something a layperson can do? I am in the process of buying a 47 year old house that belonged to my late aunt. She was not a person that did preventive maintenance although the WH is somewhere around 6-10 years old. I figured I would just get a trusted plumber I know from church to service it once or twice a year.

If you have a trusted plumber, you're good to go.

That said, whether or not you can do these basic procedures depends on how mechanically inclined you are.

I am not mechanically inclined. I'm surprised I can change a light bulb without help. My problem is I am a visual learner. If I watched somebody check the anode rod or drain the WH, I could probably do it but if I read something about how to do it, I would be lost.


I know how to put windshield washer fluid in my car. :-)
