Three New-Construction Projects We Take On

New-construction plumbing covers a lot of ground. These are the three project types we handle most.

01

Custom homes and additions

From a ground-up custom home to a room addition or a major remodel, we handle the full plumbing scope: the rough-in in the slab or walls, the top-out, and the finish work. We install to the approved plans, size the system for the home, and coordinate with the builder and inspectors so it comes together on schedule.

02

ADUs, casitas, and guest houses

The Valley's market for accessory dwelling units, casitas, and guest houses is booming, and each needs its own plumbing run, often extending water, drain, and gas to a detached structure. We do this work regularly and know how to plumb a casita correctly, including the gas and water-heater side.

03

Multi-family and commercial builds

We provide new-construction plumbing for apartments, condos, and commercial buildings, where the scope is larger, the code is stricter, and the schedule coordination is critical. We work as a dependable plumbing partner to developers and GCs on these projects.

Our process

How We Work a New-Construction Project

Built around the build schedule and the inspector. Here is the flow.

01

You reach a real person

Call (602) 883-2787 with your project, a custom home, an ADU, a multi-family or commercial build, and your plans and timeline.

02

We review the plans and bid

We review the plumbing plans, scope the work, and provide a clear bid, so you know what to expect on cost and schedule before the project starts.

03

Underground and slab rough-in

We install the under-slab and underground plumbing to the approved plans before the slab pours, coordinating timing tightly with the builder.

04

Top-out

Once the structure is up, we run the supply, drain, waste, and vent in the walls and the gas rough-in, and call for the inspections.

05

Trim-out and finish

After finishes are in, we set fixtures, water heaters, and trim, and make the final connections so everything works.

06

Inspections and handoff

We see the required inspections through at each phase and hand off a complete, code-compliant plumbing system, on schedule.

Pricing

New-Construction Plumbing Pricing

New-construction plumbing is priced by the project, based on the plans, the size and fixture count, and the scope, so we provide a clear bid rather than a phone estimate.

Why builders value us

On a build, the cheapest bid is not the one that costs you the most; the plumber who misses the schedule, fails inspection, or cuts corners is. We bid fairly, show up when we say, install it right the first time, and pass inspection, which keeps your project moving and your other trades on track.

Our approach

Why Builders and Homeowners Trust Us on a Build

New construction rewards reliability and honesty, which is exactly what we bring.

Where we started, and still excel

New construction has been part of American Discount Plumbing since the beginning, and it remains some of our largest and most important work.

We bring decades of experience and the same honest, do-it-right standard to a build that we bring to a service call.

For a builder, that means a plumbing sub who shows up on schedule, installs it correctly the first time, and passes inspection without drama.

A dependable partner, not the cheapest bid

On a build, the plumber who misses the schedule or fails inspection costs far more than a fair bid ever would, in delays, callbacks, and idle trades.

We bid fairly and deliver reliably, which is why builders and homeowners come back to us across projects.

Reliability and honesty are the whole pitch, and they are what new construction actually runs on.

Phoenix Conditions That Shape New-Construction Plumbing

Building in the Valley has its own realities, and we plumb with them in mind.

A construction boom across the Valley

The Phoenix metro is one of the fastest-growing in the country, with steady custom-home, multi-family, and commercial construction. That keeps new-construction plumbing core to what we do, and keeps us current on how Valley homes are being built today.

A hot ADU and casita market

Accessory dwelling units, casitas, and guest houses are increasingly popular here, often extending water, drain, and gas to a detached structure. We plumb these regularly, and we know the considerations that come with a separate small dwelling on the property.

Slab construction

Most Valley homes are built on a slab, which means the underground plumbing rough-in has to be installed precisely to the plans before the pour, because changing it afterward is expensive. Tight coordination on that rough-in phase is one of the things that keeps a build on schedule.

Heat and equipment placement

In our climate, where the water heater and equipment sit matters, and many new Valley homes place equipment in garages or attics that get brutally hot. We plumb for sensible placement and for the realities of how the equipment will live in the heat.

Gas roughed in for modern appliances

New Valley homes increasingly want gas ranges, tankless water heaters, and outdoor gas, which means roughing in properly sized gas during construction. As a gas specialist, we make sure the gas system is sized and placed for what the home will actually run.

Hard-water-ready homes

Because Valley water is hard, builders and buyers increasingly want a home that is ready for a softener and treatment. We rough in for water treatment during construction so the system can be added cleanly rather than retrofitted later.

Permitting and inspection across cities

New construction is permitted and inspected at each phase, and the process varies across Phoenix, Scottsdale, Glendale, and the other Valley municipalities. We know those processes and schedule the inspections so they do not hold up the build.

Expertise deep-dive

The New-Construction Details That Keep a Build on Track

New-construction plumbing is about doing each phase right and on time. Here is what experience brings.

01

The rough-in, top-out, and trim phases

New-construction plumbing happens in stages: the underground and slab rough-in before the pour, the top-out of supply, drain, waste, and vent once the structure is framed, and the trim-out of fixtures after finishes. Each phase has its own inspection, and doing each correctly and on schedule is what keeps the whole build moving.

02

Getting the slab rough-in right the first time

The under-slab plumbing is set before the concrete pours, and a mistake there is buried and expensive to fix. We install the rough-in precisely to the approved plans and double-check it before the pour, because this is the phase where errors cost the most.

03

Sizing the system for the home

Supply lines, drain and vent sizing, and gas all have to be sized for the home's fixture count and demand, per code. Getting the sizing right is what gives the finished home good pressure, proper drainage, and appliances that perform, and it is basic competence a new build depends on.

04

Gas rough-in for tankless and appliances

Modern homes with tankless water heaters, gas ranges, and outdoor gas need properly sized gas roughed in during construction, when it is far easier than retrofitting. As a gas specialist, we make sure the gas system is sized and routed for everything the home will run.

05

Coordinating with the GC and the schedule

Plumbing on a build is a relay with the other trades and the inspector, and being ready at the right moment, and calling inspections on time, keeps the project from stalling. Reliable scheduling is as much a part of new-construction plumbing as the pipe itself, and it is why builders value a dependable sub.

06

ADU and casita considerations

Plumbing a detached ADU or casita means extending water, drain, and often gas to a separate structure, with its own water heater and fixtures and sometimes its own connections. Doing it correctly so the small dwelling functions like a real home takes know-how we have built up on these projects.

07

Building in hard-water and treatment readiness

Since Valley water is hard, roughing in a loop or location for a water softener and treatment during construction lets the owner add it cleanly later, rather than facing an awkward retrofit. It is a small step at build time that pays off, and we build it in when the plans call for it.
