Domestic Water Line Freeze Protection (commercial)

[Brady Grant]

I have a domestic 3/4" water line that is insulated. Running very close to a Building Relief air damper. This damper is very large and modulates to maintain a building pressure. If damper fails, this could result in outside freezing air from the winter to come into the building.

How far away does the 3/4" pipe have to be away from that opening?

Not a train engineer

But if the water line is in a room and that damper opens to that room,,

To me the room will be as cold as the outside, unless heated, which means freeze outside,,, freeze inside

Water line freeze especially 3/4

Just my thoughts

Is it pex or what??
