Draining HW Heater

[archham]

I am trying to drain my HW heater on my Surveyor SV210. I took what I thought was the drain plug out and it had a sacraficial anode on it. I saw in another post what this was - but very little water came out when I took it out. There is a drain tube under the camper that is lined up with where the HW heater is. I was under the impression that this drain drained the freshwater tank - any chance it drains the freshwater tank AND the HW heater?

archham,

The Anode Rod you removed is the water heater drain.

Question
How do I drain my water heater?
Answer:
If the RV is to be stored during winter months, the water heater must be drained to prevent damage from freezing:

Turn off electrical power to the water heater either at the switch from the electric element or a breaker.

Shut off the gas supply to the water heater.

Turn off the pressure pump on the water system.

Open both hot and cold water faucets.

Remove the anode rod from the tank.

The drain under the hot water heater might be for the hot water (or cold) lines. You may have drained most of the water out of the tank when you drained the lines, depending on how the lines are plumbed.

Thanks to both - I thought that had to be the place to drain the HWH - just did no know where that water could have gone otherwise. I did open up the low point drain last time we used it and it was sitting at such an angle that allowed for good drainage. Maybe I emptied it then... will do it again just to make sure.

If you want the water heater to drain quickly after you pull the anode rod out open the pressure relief valve at the top and don't stand in front of the opening. Once it's drained close the pressure relief valve. I install a pvc plug in place of the anode rod for winter storage so the tank doesn't become a home for any critters.
