Now do the sacrificial anode in your water heater.
I feel like the sediment would bury the element well before the anode becomes an issue. I'm just imagining this person doesn't flush it either.
You uh... Have you checked your water filters?
In a tank water heater you react out calcium and magnesium when your heat. Tap water varies but you will get sediment from disolved minerals that will eventually bury the element if not flushed out.
How long are they supposed to last? I have an extra because the guy who sold me the heater convinced me to upgrade from the factory model. He said the stock ones failed too early. It wasn't a huge cost and I didn't know enough about it to doubt him so I just did it.
It really depends on the properties of the water where you live. I have lived places that needed replacing every 2 years and I have lived places where it was still fine after 20 years. You’ll know when it’s time to swap it, it will look like shit.
Haha good to know. Thanks.
If your hot water starts to smell like sulphur, that can also be a sign. Especially if it's worse when you don't run it for a day or two.
