Have you ever replaced your water heater anode rod?
 

This video didn't sound interesting, but his videos have never disappointed me:

Mom has complained many times about how quickly her water heaters die, could it be this [relatively] easy?
Home Depot has a 3-section anode for $35: 3/4 in. NPT X 42 in. 3-Section Aluminum Anode Rod
Lowe's has one for $40 and another for $50, so if you decide to do this, make sure you find out what kind of nipples your water heater has.
I certainly never thought I would use that sentence.
Imagine going to the store, seeing two types, calling home, and trying to cut to the chase: "Ma! What kind of..."

Both say "Can be installed with only 14-in clearance."

I would rather drill a hole in the ceiling and patch it afterward than replace my water heater more often than necessary, but I would totally pay a little extra for a three-section staff.

I wonder how this fellow would feel about one of those: https://www.youtube.com/watch?v=pUWoUM4Wttc

I've enjoyed all of the Technology Connections videos.

We can't say what causes mom's water heaters to go early without examining the cause of failure.

It could be scale buildup, or the sacrificial metal may have become depleted...

I thought about flushing my water heater recently, but then needed hot water right away and abandoned the idea. Figured if I were to flush it, then I've also got no excuse to not check the anode.

Yes. Long ago, but it seems I did it twice for some reason. It's an eight gallon tank.

I have thought about running a couple hoses to the water heater and melting some ice while I dump sediments.

Yay laziness!

Even though I have already stayed in hotels and houses with boilers like those, I never had to do the maintenance of a boiler. But anyway, I guess the tanks of those solar heating systems are supposed to also feature an anode rod.

Yeah there's stuff I can think of that I would much rather spend $500 on than a new hot water heater.
A hot water heater is potentially a bomb and needs to be cared for properly.
I recommend a magnesium anode, ball valve drain and if it's electric only put a straight element in the bottom, change the magnesium anode every 2 to 3 years.

I'd be quite concerned about magnesium, as it's supposed to explode when it's hot and in contact with water.

Maybe it's an alloy. Nearly everything is an alloy. Steel is an alloy, yet we call aluminum wheels "alloys". I'm sure "mag" wheels are an alloy as well.

Sure it might be an alloy. The cost of a magnesium alloy might be quite high though. When it comes to aluminium, AFAIK it would always be used as an alloy, never pure, in contrast to cast-iron which for some applications may not have anything else added to it.

They are high enough magnesium content to hiss when dipped in vinegar.
The main explosion danger is a steam.

I'm not afraid of hot water heater bombs mostly because I don't even know anybody, who knows anybody, who knows somebody that was harmed.

I did watch the Mythbusters episode though, and that was quite entertaining.

Perhaps the 1st stage of rockets should be steam powered hot water heaters?

lol)) doing that once a year.

Usually the case splits and all you get is a bunch of water damage.

Mine is located in the basement, in what I refer to as the boiler room where the furnace also lives. 2ft from the drain, so water damage would only be possible if it split on the side facing the drywall.

Youtube insisted I should watch the video. Turns out I was wrong, I replaced the heating element, not the sacrificial anode.

My heater has no connections on the top, hot at the top of the side and cold at the bottom. And it doesn't have the fancy feature with only one heating element.

Since I long ago raised the bathroom vanity up 2" I could R&R the heater into an insulated box. I already have a manual on/off switch.

One disappointment was he used the term 'dip tube' when one of my new favorites is 'downcomer'.

I spent 4 years without replacing the heating element of the shower at home, but I don't know how many times my father eventually did it while I wasted my time with my mother staying at her apartment :turtle:

Last time I had to replace the heater element, which was around 2 months ago, as I wasn't finding the appropriate heater for my shower, I had to compare the one for the 220-volt version to some random 127-volt until I found out one which seemed to have the same size.
