Drain or dont drain H/W heater

Just curious what the community here does with their hot water heater between trips.

Do you drain or not drain between camping trips?

I've seen some folks at the CG packing up and draining their heater, but since our heaters don't have a drain valve it seems to be a lot of effort.

Any benefit one way or the other?

It would seem that an empty tank with residual water wouldn't allow the anode to do its job.

Hi, I drain mine after every trip and drain out the system. We get lots of mineral build up from the water where I live.

I forgot to add that while there is no drain valve, there is a rather large nut attached to the heating element that is where to drain it from. Be advised that once that is loosened it will come out under a feed deal of pressure. Do not stand in front of it.

I drain mine everytime. I don't want that weight working against the WH mounting while I drive.

Atwood has a 1/2" drain plug that I remove (and then screw a short piece of 1/2" PVC into it to allow me to direct the water into my sewer hose as the last step at the dump station).

I just drain mine once a year for winter. No problems, and I still have about 75% of my anode rod left after 5 years.

The only time I drain is at the end of the season when I winterize the fifth wheel. I've been doing this for 10 years without any issues.

X2.

But I'm sure that anode use depends on the water in your area, so you may need to check more often. Experiance will tell.

I don't winterize (heated shed) but do drain the HW tank every fall and leave it empty over the winter.

The less times I unscrew the anode rod the less chance I have of cross theading it when I put it back in. (I have that "special knack" for things like that.) I drain mine at the end of the season and replace the anode rode when I do unless it's in really good shape. I do have low point drains on both sides of TT and it seems like one must get some water out of the water heater as It has to refill the next time I use it. I do drain those if the TT is going to sit for more than 2 weeks.

I only drain it for winter too, can't see any reason for continuously doing this.
