Whole House Repiping in College Park, GA

In a house built on a concrete slab, the original water lines frequently run underneath the floor, buried in the soil below the concrete. When those lines start to fail, whole house repiping usually takes a different path: new supply lines go up and over, through the attic and down inside the walls to each fixture, and the slab is left alone. Alpha Plumbing and Sewer can plan a College Park repipe either way, depending on how the house is built and where the fixtures sit.

Signs the lines under the slab are failing

• A warm patch on a tile or concrete floor, which can mean a hot water line is leaking underneath.
• The sound of running water when every fixture is off.
• A water meter that keeps turning with the house quiet.
• Damp or lifting flooring, or a water bill that climbs with no change in use.

One slab leak can be located and repaired on its own, and leak detection and repair is the place to start. When a second or third leak appears, or the same aging pipe runs throughout the house, rerouting the whole system tends to be the longer-lasting answer.

Going overhead instead of through the floor

Rerouting means retiring the under-slab lines and running new ones through the attic, then down inside walls to sinks, toilets, tubs, the laundry and the water heater. The advantages are real: no jackhammering through finished floors, pipe that can be reached for future service, and any later leak shows up as a ceiling or wall stain rather than staying hidden under concrete. The trade-offs are openings at the top of walls and at each fixture, and attic runs that need insulation against winter freezes.

When a short run under the floor still makes sense

Some fixtures are hard to reach from above. A kitchen island sink is the classic example, since no wall rises above it. In those spots the plan may call for a short new line under the slab or a route through cabinets and the floor structure. That means cutting and patching a small area of concrete, so the estimate should show exactly where and how the floor will be restored.

Material and layout choices for slab homes

PEX is well suited to overhead routing because it bends and can drop through a wall cavity in one piece, with no joints hidden inside. Some owners choose a manifold in a utility closet or garage, with a separate line and shutoff for each fixture. Copper is possible too, though the longer vertical drops mean more cutting. Whatever the material, the line from the meter to the house is a separate system; if it is also failing, that is a job for main water line repair.

What College Park's code requires

Plumbing permits come from the city's Department of Building and Inspections, which also handles plan review and inspections. The city code makes it unlawful to install, alter or repair plumbing without first applying to the building official and getting a permit. Inspections are made by the building official or authorized representatives, so plan the drywall work around the inspection date rather than ahead of it.

Questions about repiping a slab home in College Park

Will my floors be torn up during a slab-house repipe?

Usually not, when the new lines are rerouted overhead. The openings are in walls and sometimes ceilings, at fixtures and along the path from the attic. The exception is a fixture with no wall above it, such as an island sink, where a small section of floor may need to be opened. The estimate should name any such spots in advance.

What happens to the old pipes under the slab?

They are disconnected at both ends and capped, then left where they are. With no water in them, they can no longer leak or waste water. Removing them would mean breaking up the floor along their whole length, which defeats the purpose of rerouting.

Will hot water take longer to arrive once the lines run through the attic?

It can at a fixture that ends up farther from the water heater than before. Keeping hot runs as short and direct as the house allows, insulating them in the attic and sizing each line correctly all limit the wait. If a distant bathroom matters to you, ask how long that run will be and whether the layout can shorten it.
