Removing anode rod to drain hot water heater.

I have a Flagstaff 831BHDS. I'm removing the anode rod to drain the hot water heater after each use. I do this to extend the life of the anode rod. However, I cannot prevent the water from running into the interior of the camper. Water runs under the heater into the cabinet and into the kitchen floor. I've never had this happen in other campers I've owned. Anyone has this issue and offer any advice on how to prevent the water from running inside?

1st of all, I doubt removing the anode rod after every camping trip is gonna make a huge difference in how long the anode rod lasts, unless you have really hard water. If even you have to replace it 1 year sooner, it is a lot of trouble to remove that puppy after every camping trip, unless you might go months before then next trip.

I had the same problem of water running back into the camper when I drained my water heater for winter. I recaulked the bottom where the outside flange meets the inside flange, and that cured the problem. I also caulked up the sides a bit, in case the water backed up some if the camper wasn't exactly level.

You could also fashion a "chute" out of aluminum foil to divert the water out of the compartment.

There is a also an anode rod available that has a drain petcock that allows you to drain the water heater without removing the entire component, but you think I could find that on the web tonite.....nnnooooo.

Throw a couple 2x's under the wheels of the opposite side of the camper before you drain it.......

Yes, leave the anode/plug in. From what I can remember, an anode rod is $15 - 20 to replace. Sure seems like way too much messing around IMHO not to mention potential water damage to the floor. Drain the WH at the end of the season.

If the anode rod is doing the job it's supposed to do, it should last at least a couple of years, unless you've got some real skanky water that will corrode the tank. I drain my HW tank when I winterise, not beteween trips.

The hot water is for showers and washing dishes. You're not going to be drinking it.

The concept of the anode rod is that same as "zincs" on a boat. It's a sacrificial metal that will corrode instead of the steel water heater barrel going rusty. If you're really bothered by it, replace the water heater with a composite plastic one that doesn't need an anode rod. I don't remember which brand is composite and can't be bothered to go look what brand I have (which has an anode rod).

My WH drains into its compartment, but that compartment doesn't connect to the inside of the rig. Even so I'm going to make a small aluminum chute to carry the water overboard.

I to drain my tank after each use I've had to many issues with high sulfer content from cg water.
1 or two times of that and its just easier to drain it after each trip.
I also like the fact that I'm continuously draining lime and scale deposits.
My then 6 year old flagstaff had the original anode rod when I traded it last year and looked 75%.
I don't mind the extra effort.
As stated previously caulk the lower edges.

Don't see the fuss, takes about 10 secs to unscrew the anode rod and about 30 secs to re-wrap with teflon tape and re-install. I carry a new spare just in case, they're less than $15 and fit right in the wh compartment along with the 6" long 1/2" drive extension and 1-1/16" socket.

I know where I live has hard water and I have been taking mind out between trips also. It doesn't take but a couple of minutes to do. My anode is pretty much on the outside of the TT so I don't have water going inside my camper. Kinda like a cheap insurance if you ask me.

This is the 5th camping season without draining my water heater except in the fall, and this is my anode rod:

Can't respond to the sulfur problem with water sitting in the water heater.

Regardless, every member needs to do what they think best. I can't fault someone that wants to drain after every trip......that is their decision. For me, I got enough other stuff to do when I get home than to mess with draining the water heater.

Ditto. 3 years old and only drain and flush at winterizing.
Same OEM anode rod it came with. Maybe this year I will treat it to a new one; will find out when I yank it in October/November.

Last year it still had 75% of the anode material on it. Looks bad but still working as long as there is any anode material left.
