Pipes exposed to "severe cold" including outdoor hose bibs, swimming pool supply lines, and water sprinkler lines. (If you have swimming pool or sprinkler supply lines, they needed drained too.)
NJ American Water says property owners are responsible for maintenance of the water service line from the curb to their house, as well as home piping. How to prevent your pipes from freezing in winter
Experts share how to prevent your pipes from freezing this winter ahead of freezing temps and holiday travel plans, as well as what to do to thaw frozen pipes.
Hot water service piping can also be traced, so that a circulating system is not needed to provide hot water at outlets. The combination of trace heating and the correct thermal insulation for the operating ambient temperature maintains a thermal balance where the heat output from the trace heating matches the heat loss from the pipe.
Pipe insulation cannot prevent the freezing of standing water in pipework, but it can increase the time required for freezing to occur—thereby reducing the risk of the water in the pipes freezing. For this reason, it is recommended to insulate pipework at risk of freezing, and local water-supply regulations may require pipe insulation be ...
A vapor barrier on the warm side of the envelope must be combined with a venting path on the cold side of the insulation. This is because no vapor barrier is perfect, and because water may get into the structure, typically from rain. In general, the better the vapor barrier and the drier the conditions, the less venting is required. [7]
Cover your pipes with insulation. That includes pipes located on outer walls, close to windows or in places without heat like basements. Close your garage doors and crawl space openings before ...
CPVC sprinkler pipe inside a firestop mock-up. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
