Pittsburgh, PA (PRWEB) January 05, 2013 -- “If pipes do freeze,” says Beall, “the first sign may be a faucet that refuses to yield water. But all too often, the freeze-up is announced by a flood from a break.” Water expands about 8 per cent in volume as it begins to freeze, generating pressure that splits pipes, especially where expansion is impeded by joints or bends. “Ice may form throughout a long straight section of supply line before it meets and obstruction and cracks the pipe; thus, says Beall, “the entire length of pipe that supplies a stopped faucet should be considered suspect, both for ice blockages and leaks.”
