Rolland,
The city AHJ has only referenced the connection to the municipal water main
connection as it enters the building. I do not believe that it would affect
the connection or installation of the BFP on an Anti-freeze loop on a

By fed. And most state laws, the water purveyor is responsible for the water
quality up until the backflow device. The backflow device represents the
Owners responsibility to protect the water purveyors supply from anything
the Owner does with his water.

The NRC Canada's IRC has an interesting article on the use of SSP QR heads to
protect tempered glass windows, but I don't believe ICC has adopted any of

One concern I have is for dry pipe and preaction systems. The in-rush to
fill the system will have a short term high velocity flow that will pick up
any debris in the fire line and move it into the riser. Should that be added
to the flushing proceedure or is it a special case that that does not

Why would that velocity ever be more than 5 FPS? Even in the case of a dry
