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.)
It would be good to know the location of your water shutoff.
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 ...
The contactor or controller may include a thermostat if accurate temperature maintenance is required, or may just shut off a freeze-protection system in mild weather. Electrical heat tracing systems may be required to have earth leakage (ground fault or RCD) devices for personnel and equipment protection. The system design must minimize leakage ...
Equipment designed for use in particularly extreme cold conditions (such as the polar regions) also undergoes a "winterization" process.Many complex devices (automobiles, electronics and radios) as well as common materials (metals, rubbers, petroleum lubricants) are not designed to operate at extremely low temperatures and must be winterized to operate without severe damage from the elements ...
“One thing we see a lot is where folks haven’t drained their outdoor pipes before temperatures drop,” said Ala. “As the water freezes, it expands and essentially blows your pipes ...
In kitchens and bathrooms, mixer taps are commonly used. In this case, hot and cold water from the two valves is mixed before reaching the outlet, allowing the water to emerge at any temperature between that of the hot and cold water supplies.
