Have to be careful with them when the temps are below freezing. Depending on your situation and what is available on site. This may not be the most practical. I personally think the old milk releaser or a hobby releaser is a more practical way to go. Quite a few people on here are using the small Gast vac pumps for a pretty reasonable price $150.00 to $250.00 and a hobby releaser for $550.00. Might save you some money going that route. And there is always the milk vac pumps that can be had pretty cheap as well and easily converted to run on a small gas motor. Lots of different options depending on your options available on site (electric?)
