That's a nice setup. Mine you have to unscrew just to drain it, nowhere near as convenient. I drained mine last weekend before adding more fuel, it's been running great. Last night I got another 8 gallons for it, that should get me close to the top of the dam built, about 8hrs of run time.
Here's where it's currently at, added another 25-30 buckets last night. I'd like to get a total of about 6" on the top of the dam this morning, but if my work calls I'll be heading in. The last bit got poured on so that's settled in pretty good, next rain is predicted for Friday so I'm trying to get another layer down before then.

This one is taken from a good bit rather back, hard to see with the shadows.

Tried to get two from the left side to show the slope/grade on the back side of the dam. I added a bunch of buckof topsoil to it last weekend where the grade is set, about 15' of the lower side of the dam, the top is pretty flat now, so it will be a while before I add anymore topsoil.
