I am working on a dry system where we have to install some drum drips. However,
they will be installed in the cold spaces (outside, not cooler/freezer). Do
these need to be protected from freezing? Any suggestions how?

And as mentioned in a different manner- after draining, open the bottom valve,
lift a bucket of AF solution up around it, reach in and shut the lower valve-
frost proofing. Doubt the flammability matters if the brass in the valve melts
and allows the solution out in advance of water from the
Roland, I'm not the EOR on this project, just the plebe doing the shop

now the dormers on both ends of the building are trapped. So far he has been
