Plumbing in Sioux Falls has to be sorted from wind-driven rain. A ceiling stain under a lifted edge is often not a supply line. If the fixtures are off and the meter is moving, use the main shutoff and hunt the leak. If the meter is still, look at the windward roof, the window heads, and the window wells before you open a wall. Those paths fill in the same thunderstorm and they are not the same repair.
Sill cocks and garage lines freeze when the wind can reach them, and that is worth a fall shutoff. It is not every wet ceiling in July. Water heaters, stuck valves, and older drains in the central neighborhoods keep their own calendar. Scale shows up on fixtures. A weeping tank needs the vent, the pan, and the shutoff discussed, not only the new tank. If a gas vent is lazy and you smell trouble, stop using it.
Finished basements hide a leak until it has traveled. Edge houses with irrigation and long hose-bib runs fail in the wall and show up in a ceiling that seems unrelated. Say whether the wet spot followed a blow and a hard rain. A crushed gutter overflowing into a well is a drainage fact. A rocking toilet and a slow floor drain are plumbing facts. Roots and a belly in the line will not be healed by a cable. Ask about a camera if the clog returns.
Sump pumps should discharge away from the foundation and not into a sanitary line they were never meant to feed. Know where the water goes. Clay pockets and window wells will test that discharge the next time the wind drives rain at the house. A pump that runs on a dry day is a different clue from a pump that runs only in the storm. Say which one you have so the visit starts in the right hole.
Say leak, drain, sump, or water heater, and name the neighborhood. Say if you can shut the water off. If the wind and the rain started the stain, put that in the first breath. A sagging ceiling is not a container. Call the number on this page.
