How to drain Water heater?

I arrived back from my first RV trip which was AWESOME! Now I would like to drain water heater since I wont use it for about another 2-3 weeks. My water heater has a rod at the bottom(Can't think of name). The one that gets eatin at by corriosn before the water heater. Do I take that out? I dont have a big enough wrench and dont want to really buy one. I also have the hot water low points which did not drain the water. Maybe just slow. Or should I just keep the water in there?

I beleive the anode rod is what your seeing. I can't remember the socket size, but you will need to get one to remove the rod and allow the water to drain. Be sure to open a hot water faucet inside the trailer before removing the rod.
Also using teflon tape on the rod's threads before reinstalling will help the next time you need to remove it.

Glad to see your trip went well
I do not drain my water heater after each trip (so far has been 2 to 4 weeks apart) but I also do not live in an area where it freezes that often either.

I usually drain mine if it's going to be a month or more between trips.

in 5 years of owning my trailer, i've never had to drain my WH.

if a long period of time goes by, i just flush the system out.
never have had bad water issues.
our area water is good but i know that other areas of the country, have bad water.

I have good water. I just don't want it full of bacteria or something else next time I use it.

Its more of going bad once in there. Not the water first water placed in there.

I've owned fifth wheels for 7 years and I never drain the water heater until it is time to winterize it. The water won't go bad. There have been times when the trailer wasn't used for six weeks.
After you break camp and disconnect from your water supply or, if boondocking and turned off the water pump, just open a faucet to relieve the pressure and then close the faucet.

Don't make camping a chore.

I pulled and drained my water heater for the first time this past fall. Mine sets all winter and usually sets more than a month between trips in the summer. Never an issue with water taste. Anode rod had abt half left.
I wouldn't be concerned. Ur anode rod is going to respond to the conductivity (mineral) content of the water. Our water here isn't as much of a problem as other areas.
I purchaced my trailer new 9 yes ago. Our winters aren't as severe so I can get away with covering the outside of the water heater and drain the rest.

Yes, you should bleach the tank. If you drain the water heater you will still have some water left in the lines and in the filter. If you are concerned about water getting nasty you should also be concerned about this water too. I just leave the water in the heater and if it is more than a few weeks between trips fill the fresh water tank and add the bleach. Open the faucets and when you smell the bleach you know the water heater has bleach in it. Let it sit a while and flush and you are good to go!

dont forget to either remove or replace the filter after you bleach the water - bleach kills the charcoal - or atleast that was what I was told

I do not have a filter. Well I guess I kind of do. It's just a sand filter. Large particle stopper.

I am usually too concerned about this type of stuff so it's nice to have people fill me in.

I drain mine all the time, not for any other reason than I can, simple to do, simple to replace, also it flushes any hard water deposits out of the heater.

Amazon.com: Camco 11533 RV Anode Rod with Drain for Aluminum Water Heater: Automotive

Looks like it is for the Atwood Aluminum Heater only.
