Plumbing in South Dakota includes wells, pressure tanks, and town systems, and the wind gets into the story when a roof leak pretends to be a pipe. Water driven under a lifted edge can stain a ceiling that has no supply line above it. If every fixture is off and the meter is spinning, hunt a supply leak and use the main shutoff. If the meter is still, look at the windward roof and the window heads before you open a wall.
Exposed lines and sill cocks freeze faster when the wind can reach them. A crawl space vent left open to the prairie, a hose bib with no inside shutoff, and a kitchen on an outside wall are the usual failures. That is a real cold-weather fact. It is not the whole trade. Sumps in east river clay, septic fields, and a water heater weeping at the base keep the phone busy in months when the wind is only a background noise.
A cable clears a clog. It does not repair a belly in a line or roots under an old shelterbelt. Ask about a camera if the stoppage returns. Water heater work should name gas or electric, tank or tankless, the vent, the pan, and the shutoff. Wind can affect a flue that was already lazy. If you smell trouble at a gas water heater, treat it as a stop-using-it problem, not as a draft to live with.
Rural houses need the well in the first sentence: pressure tank, no water, or water that went muddy after a hard blow shook the line. Town houses need the basement and the floor drain in the first sentence. Do not tie a sump into a sanitary line it was never meant to feed. Know where the discharge goes before you trust the pump. A discharge pointed at the foundation will be back.
Say leak, drain, well, or water heater, and name the town. Say whether you can shut the water off. If the stain showed up after a wind-driven rain, say that so a roof leak is not chased as a pipe. A sagging ceiling is not a bucket. Call the number on this page.
