Plumbing in Oklahoma often disappears into a slab. A warm line on the floor, a meter that turns while every tap is closed, a hiss you cannot find: that is the classic leak in a brick ranch. Garage water heaters rust out beside the car and send water under the wall before anyone sees a drip. Cold snaps split hose bibs on the north side. Clay soil shifts, and a lateral that was fine in dry weather settles into a belly.
Open with leak, drain, or hot water, and say slab, crawl, or basement if you know it. Most newer houses are slab. Some older town houses are not. Pretending otherwise wastes the visit. If the water heater sits in the garage, say whether the pan is full and whether the unit is gas or electric. If you smell gas, leave and say that first on the call from outside.
Drains here get roots, belly, and the occasional flat run to the alley or the street. One slow sink is a trap story. Two slow fixtures are a line story. A wet spot in the yard that smells wrong on a dry, windy day is not irrigation. Say it plainly. Storm rain that backs up at a floor drain is a timeline, not proof that the supply burst. Wind does not clog a pipe. Debris and roots do.
Irrigation ties into this trade more than people admit. A failed backflow or a zone valve that will not shut can look like a slab leak and can flood a bed against brick. If you have sprinklers, say whether they were running. Before a hard freeze, the system needs to be off and drained back, and if you do not know how, that ignorance is a fair thing to admit on the phone. Burst zone lines are a cold-morning classic.
The next front will test hose bibs and any joint already seeping under the slab. Call with the town and a clean sentence about where the water is going. If you already shut the main, lead with that so nobody tells you to do it twice. Call the number on this page.
