New Construction Plumbing in Allentown, PA

Inspection-Ready New Construction Plumbing Services in Allentown, PA

Final Trim and Fixture Setting in Allentown

At trim we install toilets, faucets, garbage disposals, dishwashers, ice maker boxes and laundry connections. We work with fixtures from Moen, Delta, Kohler, American Standard and the other brands builders commonly specify, or with owner-supplied fixtures. Every fixture is checked for flow, drainage and leaks, and angle stops are set straight and tight. We finish by running every fixture at once to confirm the system drains and vents properly under load.

Rough-In and Top-Out Plumbing in Allentown, PA

Once framing is up, we run supply and vent lines through the walls and attic and set every stub-out for sinks, tubs, showers and appliances. We usually install PEX-A with a central manifold so each fixture gets its own line and shutoff. Shower valves are set at the heights you choose, and tub sets are installed and protected before the drywall goes on. A full pressure test is held for inspection so nothing hidden in the walls is ever in doubt.

Permits and Inspections for New Plumbing in Allentown, PA

JKR Plumbing handles all required plumbing permits and coordinates with local Allentown inspectors throughout the new construction process.

Gas Line Installation for New Homes in Allentown

If your new home will use natural gas for heating, cooking, or water heating, JKR Plumbing provides safe and code-compliant gas line installation. This involves running new gas lines from the main supply to all gas equipment. Our licensed plumbers ensure all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.

Gas Piping for New Homes in Allentown

We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both available, and CSST is bonded per manufacturer and code requirements. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything runs at once. The system is pressure tested and inspected before the utility installs the meter.

Guest House, ADU and Addition Plumbing in Allentown, PA

Guest houses and additions need plumbing that ties into the existing house without overloading old drain lines. We locate the existing sewer, check its condition with a camera and confirm there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, based on distance and pressure. We also handle the trenching between structures and restore the yard when we are done.

Fixture Installation and Finishing in Allentown, PA

Once the rough-in is complete and walls are up, JKR Plumbing handles the final installation of all plumbing fixtures. This includes sinks, toilets, showers, bathtubs, dishwashers, and washing machines. We ensure everything is perfectly aligned, sealed, and fully functional, providing a polished finish to your new home's plumbing system.

Underground and Under-Slab Plumbing in Allentown

The underground phase sets the drain, waste and vent layout that every fixture in the house will rely on. We trench, bed and slope PVC or ABS drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab or foundation with sleeves. Rocky, clay-heavy soils are common in Pennsylvania, which can make sewer and water line excavation more involved. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left exposed for the inspector before your concrete contractor pours.
