To drain or not to drain?

Somewhere along the way, I got into the habit of draining the fresh water tank and hot water heater tank whenever we came back from a trip and parked the RV for a while ( week or so )

Anyone else do that, or not do that?

I do the freshwater tank but very seldom do the hot water tank. It gets drained maybe once a year when I inspect the sacrifice anode...

I always drain the fresh water tank, but haven't drained the water heater in 37 years, never had a problem.

Only a week, probably not. But once I forgot to drain the hot water tank and did not use the trailer for two months. When we did use it again the hot water smelled awful. This was with well water, which is not chlorinated. Had to drain the tank and bleach the system.

If we park our TT for more than a few weeks I drain the HW tank. Good idea to flush it with one of those wand thingies and sanitize the FW tank and lines each year.

We use our rig year round but often are home for 3 weeks or more. When that happens, I drain and bypass the wh. Fill it up when arrive at the next CG.

Another benefit is the anode seems to last much longer.

I always drain the FW tank. The HW tank, gets drained if we are not planning to go out for a few weeks, typically three weeks is my threshold.

I drain my fresh water on the ground while I travel home from the CG so that the bikers think I'm dumping poo on them and I drain the water heater at the end of the season. I fill the tanks at the campground using "city" water which is chlorinated so I've not yet had any issues with stinky hot water due to leaving it sit.

We use our RV year round and also as a disaster preparedness plan. I keep the water full at all times. I drain it only to sanitize the system. I use only chlorinated water in the tank.
