Yes, but usually the Water District has final say and specs. Mad Dog

Expansion, and that pipe needs to be properly secured once the wall is opened.
Intplm.
Re: Loud banging from wall (with video)
That's not air. That's some nasty expansion. Open the wall.

Re: Black soot around gravity heat registers
Please check back in @anne29b. But turn off the gas and electric to the furnace first.

Re: Base Ray Installation
Base Ray is the best. You need special tools to assemble it. Some supply houses rent them. You will have to check around. If you find a supply that sells Burnham Base Ray they can probably help you out.
Look for the install instructions. They want the wall behind the Base Ray insulated and you need the piping instructions. Base Ray is assembled with push nipples.
If you can configure it with standard lengths, then no assembly will be needed

Whether it's required or not, it would be a good idea to have one…

either the hose wasn't removed or they were installed incorrectly. it isn't really possible for water to stay in there. or they didn't install them with the seat in conditioned space.

let’s hopefully not base our opinion about the entire grid on one person’s reported voltage measured one day

how much gas is lost between the well and the burner on your furnace/boiler?

The only time I saw an issue with a Woodford was when a family member left the hose attached with a nozzle on the end that was closed. It blew ice out of the vacuum breaker, and yet all of it still works fine.
I currently have 4 of them in service, none of them have issues even in below 0F temps.
If they're pitched correctly and the proper length to get the valve far into the heated space, they can't freeze.
