This is a workhorse device. We use it to clean rinse and sanitize all of our kegs. Will probably buy a couple more to speed up the process.

Cleaning and sanitizing your sanke kegs just got a lot easier. I put this on the depressurized keg flip it over with the ring stand straddling a catch basin containing a powerful sump pump forcing water cleaning solution sanitizer whatever up through the keg and back into the basin. A fine mesh bag around the sump's input keeps the gunk from getting back into the keg. The pump does the work while I plan my next brew. This thing is awfully pricey and admit I pulled it out of my shopping cart a few times before buying. No regrets on the purchase now though.

I would recommend for small volume occasional use. We use it in our brewpub brewery for managing one- off kegs. We did adapt the GHF to accept a tri clover flange so we could use a pump. Definitely better than using a keg filler.
