I am hoping I will get better than 10 years out of the heater this time.....
Heater was installed in 2013. The original e lectrode gone in 2017. The replacement was gone and r eplaced today. PS - Sears is gone too come to think of it......

You don't have a dielectric union on your water lines. That's a problem.

The writing on my shows that it was installed in 1991, so I’m counting the days till it fails. Not sure if meticulous maintenance by previous owners, or if they just never took showers.
Also, Sears Home Improvement is still in business, they go by Transform Home Improvements now, and I understand they tend to be pretty cheap, but the service seems to be terrible. I had them scheduled to give an estimate on replacing my 36 year old central a/c system, and they rescheduled or blew me off 4 times over the course of 3 months, until I told them to just forget it and I’ll deal with it next year.

This is one of those things I need to do and never remember to do it.

Mine looked like it spent time on the T
itanic after 17 years, replaced
it with one with a 10 year warranty.

Sure he does.
Zinc outside, plastic inside. At least that’s what that looks like. Hard to tell without being able to be there.

Looks like a galvanized union going straight to threaded copper to me. I s ay that as someone who has made that mistake before.

hardness of water in our area means new water heater every few years, when the lime gets up to the bottom element we’re done

Oh, I am that installed it 6 years ago. as well as the one before it. What should I have done different?

Mine I noticed is starting to pop when heating which I believe if due to lime insulating the bottom. Meaning I suspect its days are numbered.

Something like this may keep the two materials from touching each other
Holy shit URL, get under control

A dielectric union is a coupling with a plastic sleeve that separates the copper from the galvanized. It keeps the two dissimilar metals from reacting.
Here’s a link to a couple versions from Menards.

You are correct it’s black iron, g alv union, and then copper . Here is an interesting thread on dielectric unions . Given the plumbers concerns, I think I will just maintain my electrodes.

My favorite observation is a 10 year old water heater is a lot heavier than a brand new one.......

The link didn’t come through, but I’m interested.

Interesting . I haven’t experienced any of these failures, but I’ve only been a homeowner for not quite a decade, and am trained as a carpenter not a plumber, so my data set is small.

I guess I figure I can afford changing the electrode every two or three years, though I am beginning to think lime build up will get it at about the same point as electrolytic failure would of. .....
Chalk it up to just another science experiment.....
