Slab Leak

Water moving under a slab with no fixture running will keep undermining the fill beneath it, so close the main and have the line traced.

When this becomes an emergency

What a pro does

Slab work is a smaller share of the calls here than in the southern states, because most Michigan houses have a full basement and their pipe is visible. Where it does turn up is specific: a postwar ranch built on grade around Monroe or Ypsilanti, a slab addition or a converted garage, or a house with in-floor radiant heat. That changes the diagnosis. The plumber isolates the hot and cold sides at the manifold or the heater, watches the meter, and uses listening equipment to trace the sound of escaping water through concrete. On a radiant system the loop itself may be the leak, which is a different repair from a domestic supply line. Once the spot is located there's a choice, and it's an honest one: break the floor and repair that section, or abandon the buried run and reroute overhead through a wall or the attic. Rerouting often wins in a Michigan house because there's usually somewhere warm to put the new line, and no one has to open a finished floor in February.

Frequently asked questions

Less common than in states where nearly everything is built on grade. Basements are the norm here, so a leak that would hide under concrete elsewhere is usually in plain sight overhead. The slab calls concentrate in ranch houses, slab additions and converted garages.
The concrete is rarely the casualty. What suffers is the fill under it, particularly the sandy soil common in much of the state, which washes out and leaves the slab unsupported. Cracking or a floor that starts to feel uneven is the later stage of that.
Often, though it depends on the house. Breaking concrete means a demolition and a patch on top of the plumbing, and if the buried run has failed once it may fail again nearby. A reroute through a heated wall cavity gets the pipe somewhere accessible and out of the ground for good.
