So walls and a handicap bathroom took precedence over the coal vac, but now I have to get back at it.

If I can find all my parts, going to start getting things ready.

Ideas on suspending the barrel above the hopper? Seems like a shelf of some kind would be in order. Not too bulky?

My barrel sits on some 2x4's that are screwed to the joists above. Angle iron would also work and be less "bulky".

When i had mine up i used 2x3 from the joists to a plywood platform. Less bulky could be bolt rod from the joists to steel platform

Yes, leaks will kill the suction power. I have used a minimalist homemade coal vac rig for a few years now. Posted online here. A rice coal buildup on the rim of the vac (where the top & bottom fit together) almost stops the suction, even with a clean filter. I just clean the rim when the top is off to clean/change the filter. With a clean and sealed system, I top off a half-filled 275 # Keystoker hopper in just a few minutes.

You might need to fix the leaks around your shutoff valves at the bottom of the barrel.
