You omitted an important step. Before draining the manufacture says that after turning off the power the water should be run at the faucet until it is cold to prevent damage to the internal tank. It is then cooled properly and can be drained
I agree with former comment.My plumber told me with a marathon never drain it before letting it cool down. turn off power to heater. He said he has seen people hook up hose and start draining without letting water to cool down and the plastic tank collapsing thus ruining the water heater . makes sense!
summary: no steel in the tank, tank is plastic, tank itself has life warranty, will not rust out. 4.5" of insulation, which helps with electric costs, as electricity is not the most efficient way to heat water... i would assume that on demand gas would be efficient, and smaller too! shut off the heater element at your breaker box, and then run the water out of a hot faucet, until it runs cold (missing this step will cost you $1,000). Drain it. Close valve to stop inflow. Open valve for 10 seconds and Add a bit of water to swish the bottom of the tank, close valve, drain. Repeat. see 2:45 on the video. Turn valve on. Fill for 10 minutes, and run hot faucet until solid water flow is attained!!! or you're out a $1,000. After she's full, Turn on the hot water breaker.
Great video - thanks...just subbed! I am considering purchasing a Marathon. I have seen a few (very few) reviews about these tanks leaking and Rheem not honoring the warranty. Have you seen any of these water heaters leak and what is your experience with Rheem warranties? Thanks again for the great video! ☘️
Had one of these, lasted 16 years. just sprung a leak somewhere in the bottom of the tank, our REC replaced it for free. I have to reinstall the new one, but these things work great.
Mine just finished 16 years also. Started leaking from under each of the three rubber grommets at the top of the heater. Filed a warranty claim, company totally blew me off. Lifetime warranty is a total lie.
@Jimmie Noble I think the difference was that our Rural Energy Commission did the warranty work, i just peeled the sticker off, left it on my back door, they took it and left me a new heater. Im sure if i had to go through the company itself it would have been a nightmare.
My propane water heater goes ........KA PoW.......sputter ..sputter.......KAPOW........throwing flames from the bottom and then a slight humming and sizzling and then she is good for another day before I have to start her up again. Do all propane heaters go like that?
You stated electric was the most expensive option for water heating. You may have overlooked propane, and its cost. I have a propane water heater and find its cost to be around $50 per month at $2.00 per gallon cost. I also have a Rheem Hybrid 50 gallon and find its cost to be less than $10 per month.
Polybutyl tank..humm didn't we have a major issue in this country with polybutyl plumbing. Driving a class action lawsuit and billions in repiping jobs?
The banned water pipe plastic is polybutylene. The plastic liner of the Marathon hot water heater tank is called polybutene. But they are the same chemical and react with chlorine found in city water supplies. The ban was for piping only, so Rheem can use the material as a tank liner. I suppose if you are on well water your tank will be fine. Rheem's product advertising information just calls this "plastic lining." a good call on the part of their PR people.

@Don G. I got lucky and read the instructions on the tank! I had done another model and don't know if I did that step, but fortunate this time
There is a vacuum break on the cold side that should not allow too much of a vacuum to form. But best to still follow Rheem procedure.

there is a vacuum relief valve built into the top of these that vents air in when draining to prevent that. Can't hurt to cool first though.

I thought you had to open a pressure relief valve? If there is no water input open, how will the pressure be regulated?
The manual states that the vacuum relief valve should be replaced every six years; what is the procedure for doing that?

Do we need an expansion tank for this Marathon water heater?
not unless you do... public water, no

Ray: I opened the valve at the bottom of my Marathon and the water was cold. Albeit I have got water at the tap. Why is that?

aren't the heating elements made of steel?
The marathons have titanium elements
@@SpencerRyllSmith that is freaking sweet. our water is 5.5 Ph and iron... this tank is awesome
You ever been told you look a little like Sylvester Stallone ?
