New Construction Plumbing in Phoenix, AZ

Inspection-Ready New Construction Plumbing Services in Phoenix, AZ

Underground and Under-Slab Plumbing in Phoenix

The underground phase sets the drain, waste and vent layout that every fixture in the house will rely on. We trench, bed and slope ABS or PVC drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab with sleeves. Arizona soils often include caliche and expansive clay, so we compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left visible for the inspector before your concrete contractor pours.

Rough-In and Top-Out Plumbing in Phoenix, AZ

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 a question.

Final Trim and Fixture Setting in Phoenix

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.

Water Heater and Recirculation Installation in Phoenix, AZ

New homes in Arizona often use tank water heaters in the garage or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is far cheaper than retrofitting later. Because Arizona water is hard, we recommend planning space for a softener loop at the same time.

Gas Piping for New Homes in Phoenix

We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both options, 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 sets the meter.

Casita, Guest House and Addition Plumbing in Phoenix, AZ

Casitas 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, depending on distance and pressure. We also handle the trenching between structures and restore the yard when we are done.

Commercial and Multifamily New Construction in Phoenix

We also plumb small commercial buildouts, offices, retail suites and multifamily projects. These jobs often require grease interceptors, backflow assemblies, commercial water heaters and ADA compliant fixtures. We read commercial plans, coordinate submittals and keep the general contractor updated through each inspection. Our crews scale up so plumbing never becomes the bottleneck on your schedule.

New Construction Plumbing Cost Planning in Phoenix, AZ

Plumbing for a typical new single-family home in Arizona runs about 4 to 8 percent of total build cost, depending on fixture count and finish level. A modest three-bedroom home often lands between $12,000 and $25,000, while custom homes with multiple suites and outdoor kitchens run higher. Choices like a manifold PEX system, a recirculation loop and fixture grade move the number most. We break the bid out by phase so you can see exactly where the money goes.
