Yes, pipes can freeze during the winter months. If temps dip below 20 degrees Fahrenheit for six or more hours, your insulated pipes are more at risk, while uninsulated pipes can freeze if temps fall below 32 degrees for around 12 hours. Exterior pipes are more likely to freeze than interior pipes. The best way to prevent freezing pipes is by insulating your pipes, keeping your home’s temperature above 55 degrees, opening cabinets and doors containing pipes to promote circulation, dripping faucets, and disconnecting hoses.

A back pressure valve is a control valve used on production vessels, such as separators, treaters, and free water knockouts. The valve holds pressure until a set point is reached, and then releases upstream pressure to reset. Back pressure valves are not safety mechanisms. Instead, they are regulators designed to keep the fluid, gas, or liquid mixture in a system at a certain pressure level to prevent bursts and other incidents.

Meanwhile, a backflow preventer is a safety mechanism that kicks in when the pressure has already failed and contaminated water flows in the reverse direction. Most backflow preventers consist of two one-way valves, or check valves assembled together. This design only allows water to pass through in one direction but not the other.

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.

If your sink is on an exterior wall that isn’t insulated, or if pipes travel through a cabinet against an exterior wall that prevents heated air from circulating around the pipes, the pipes can freeze, causing them to burst. The best way to avoid leaking sinks is to insulate the pipes and open cabinets in the short term to warm the water line up and prevent freezing.
