Double Manual Releaser?

[syrup2nv]

Anybody using a D&G Double Manual Releaser? (Horizontal) How are they at holding continuous vacuum? High Vacuum? Pros/Cons?

[syrup2nv]

How about a double in general?

I bought a new D&G Double tower releaser at the begining of last year. It worked great. I'll probably will buy another for a different sugarbush next year.

I have one and also an electric one and both work great. The manual takes a little of the pump capacity because the vacuum is broken on the side that dumps so the air has to be removed on the next cycle.
