@RoosterML Yep, great set up you have. The inside should stay clean enough to just add water with gallon jugs, if your ok not rinsing it out when it gets empty. I usually top mine off, once a week. I only rinse mine out a few times a year, some people don't feel comfortable just adding water, which is fine. I have a 14 gallon drum in the run, that I don't heat. If/when it gets below freezing temps, I'll dump it out and put it back in use in March.
