When do you drain your lines and hot water heater?

Living in earthquake country, we have always left our fresh water tank full and a stock of food in the trailer for use after California falls off the edge. The trailer lived next to our house so it was our lifeboat. Never suffered any bad effect when we took this water with on a trip. We did the usual Memorial Day, Fourth of July, Labor Day, Thanksgiving long weekends and maybe a week long vacation trip a year. so the water sat a while A three day weekend involved 170 miles each way, so hauling 50 gallons of our own water worked out. Now that we are retiring, and the new trailer is larger, it goes to a storage yard between trips. No value in leaving water aboard now. We will head to the desert this winter with 50 gallons in the tank and 5X5 gallon jerry cans for boon docking. Won't be hauling this over the mountains, but will fill all just before leaving civilization.

I let mine go too long once. And the water stunk when I hooked it up on a subsequent trip. So now I drain it after every trip when I use either city or RV water.

That is why I drain ours at the end of every trip.

I drain mine at the end of summer but may put in some clorox.

Me too.

But, I am a weekend camper so the water never sets in there for very long.

since I full-time, I only drain the water heater 2 times a year so I can look at the anode rod. since I keep some water in the fresh water tank to have water when the RV Parks water is turned off for repairs, I drain it once a year and put in some fresh.

We drain everything after every trip.

A cup of bleach in FW tank, fill, run through system, drain and refill two hours later. Repeat, with fresh water only, twice to flush bleach. I do this every six months give or take. Other than that, I don't drain the tanks or system.

Only when i winterize. I de winterize in April, then winterize in October. Between those dates, lines and water heater stay full. I do drain any unused water out of the fresh water tank i don't use at the end of a trip.

When I put it away for the winter.
