nope in a normal Cold area plumbing system right by crawlspace door theres a knurled fitting on cold shut off valve you tuir off valve oplen this fitting water runs out of house pipes to floor or bucket now nothing can freeze fore i leave i crack open a hot faucet nearest hot water heater not the one on the heater , not really winterized just no press in pipes mean any residual water in line can expand with cold temps and not bust anything , has somewhere to go as it expands then contracts while freezing n thawing .. walkin out flus toilets .. never had an issue even in alaska..
