How to disconnect & remove water heater in manufactured mobile home?

[toolguy603]

After searching around online, I have been unable to find any videos on how to properly disconnect a water heater in a manufactured mobile home, so I am here asking if anyone has experience doing so and can share their knowledge.

This water heater has had the electricity shut off to it via the breaker panel; the water in the house has been completely shut off; the water heater has been completely drained; and now I am asking how to safely disconnect the plumbing for the water heater as to remove it and then replace it.

Here is a photo of the top of the Rheem 30gal water heater:

All help is greatly appreciated.

The corrugated lines the big nuts right at the heater. Don't turn the power on the element will burn out within seconds. A non contact voltage probe or volt meter to check for power before disconnecting. Might want to put rv anti freeze in toilets , drains and all traps.

I've done a couple in MH's, from the looks I'd say that is a replacement not the factory unit. Pretty much common sense stuff, be sure power is off. Disconnecting the water supply and the hot line is pretty straightforward. You can just unscrew the copper flex lines at the top of the tank and unscrew the T&P valve. Check for an extra ground to the frame of the home from the tank, should have one.
If installing a new tank I would install an electrical disconnect box for safety in the future and it is a basic requirement. I'd install a shutoff at the cold water in line. I'd also install a drain on the pan and the T&P pipe to the outside perimeter of the home which is now a MH requirement. If reusing the corrugated copper lines I'd replace the washers in the fittings that attach to the heater.
