        "text": "Plumbing lines can be run to a kitchen island, but the installation method depends directly on your home's foundation type. In homes built on a concrete slab, routing new supply and drain pipes requires cutting and trenching the slab, laying pipe, and patching concrete. In homes over a crawl space, routing utilities underneath is generally faster and less invasive. Proper venting is a crucial detail: because an island lacks an adjoining wall for traditional vertical vent stacks, code-compliant air admittance valves or loop vents must be integrated inside the island cabinetry to ensure proper wastewater drainage.",
