Made of bits and pieces I had in the garage - a desk clamp for an Ergotron computer monitor stand, an old 15mm-1/2" BSP backplate elbow, an old garden tap, a couple of inches of 15mm copper pipe, a 15mm-1/2" BSP adaptor and a 1/2"-3/4" BSP adaptor to fit the hose coupling. The Blast fitting p***ed water sideways until I put an additional 3/4" rubber washer in there and did it up very tightly with the pipe wrench.
It works very well. We haven't got an awful lot of mains water pressure as we're at the top of a hill, but I gave 30 bottles a final rinse before sulphiting them in about 10 minutes. If you don't get the plastic spout poked up the neck of the bottle before you push down it becomes quite an effective ear rinser instead
