Before Work Begins
How the Right Solution Is Chosen
Location affects the solution
A leak under cabinetry or finished flooring can favor a reroute over direct access.
Look at leak history
Several failures may indicate a deteriorating system rather than one isolated defect.
Diagnosis Before Demolition
Confirm the Leak. Then Choose the Access.
A warm floor or high bill does not automatically identify the failed pipe. Isolation and pressure testing help confirm the system before access decisions are made.Direct repair
Opening the slab near a confirmed leak may be practical when the location is accessible and the surrounding piping remains dependable.
Reroute
An overhead or alternate route may avoid repeated slab access when the failed line is inaccessible or the existing path is no longer the best long-term choice.
Testing
The completed repair or reroute is pressure-tested before finish restoration so the plumbing result is verified first.
Restoration responsibilities
Concrete, flooring, cabinets, walls, or paint may involve separate restoration. The scope should state clearly what MRC Plumbing Solutions includes and what requires another trade.

Slab Leak FAQ
What are common slab-leak signs?
Warm flooring, the sound of water, unexplained bill increases, damp areas, pressure loss, or water near the foundation can be warning signs.
Does every slab leak require breaking concrete?
No. Some lines can be rerouted through walls or ceilings, depending on layout and the affected fixtures.
Can you locate a leak exactly?
Detection narrows the likely area and line, but field conditions can limit precision. MRC Plumbing Solutions explains expected access before repair.
