Draining Hot Water Heater

Is it as easy as the intertubes makes it sound?

Turn off heater
Let cool
Connect hose
Put hose in sump
Drain a little bit
Turn off water intake
Open hot water spigot somewhere (to prevent vacuum)
Drain the bad boy
Close drain valve
Turn on cold water
Turn on heater
Wait til water comes from hot water spigot (indicates air is out of the lines) this is the part I’m a bit uncertain on

Basically yes. It really should be that easy.

Although now that I look at your list, your turn on cold water is really undoing the turn off water intake step.

Why do you need to heat your hot water?

Everything is as easy as the intertubes until you realize something is seized up or snaps off. Sincere best of luck, comrade. You got this.

I’m happy to advise, but I will require you to take the oath of supremacy first.

That be all.

On the air part, it will spit and gurgle and sound awful until the water is running like it normally would. Should only be a minute at most. But, make sure you open all hot water spigots/faucets and get the air out of everything or the next time you use that particular one you might get a surprise.

Only thing that’s a bit off about your list is letting the tank cool. There’s no need for that, and it would take a day or so to do - water heaters are very well insulated.

Is it gas or electric?

Why? Removing sediments?

I’ll do the pledge if Allegiance

It’s five years old

I’m expecting it to act like when all the water in the house is turned off

Gas

How’d you make out with this? And what were yoi draining it for?

The least he could do is show us pictures of the 2nd degree burns he received during the process.

Had to table it, will try to do it this week…People told me to do it

People? Who are these people? Is their home maintenance knowledge on par with yours?

I would wait if you are hosting Thanksgiving. Nothing should go wrong, but in the off chance it does then it would be better if it didn’t interrupt your holiday meal plans.

I will also say that I have never been able to successfully empty my tank. I can open up every hot water tap in the house, but there is something preventing the vacuum from fully releasing. So I go through your processes and when the water coming out of the tank slows down I will flush the tank by opening the cold water inlet for a while. Let that drain as much as it can and repeat a few times.

Lots of people are saying …

“They” say you should do it to get rid of sediment to control rusting and prolong the life of the tank. I never remember to do it.

Yeah this is a weekend project for sure

Are you draining and flushing or one or the other?

I ask as I need to flush my water heater but have never drained it first and the instructions you linked don’t indicate you need to drain first so.

This is a maintenance task I like to procrastinate.
