Water Line Installation in Phoenix
New construction, water line upgrade, or replacing an aging original line. We install main water lines correctly, with the permits required by Arizona code.
New water line installation covers a range of projects: running a new line for an ADU or added structure, replacing an aging original line before it fails, upsizing an undersized line that can't keep up with a household's demand, or installing the service line connection on new construction.
Brian McQuistion Plumbing & Drain handles water line installation across Phoenix metro — permitted, inspected, and done right the first time.
What Water Line Installation Involves
We locate utilities, pull the required permit, excavate to the required depth, install the new line using the appropriate material, connect at the meter and at the house entry, backfill and compact, and restore the surface. We coordinate the inspection with the municipality.
Materials and Sizing
Residential water lines are typically 3/4 inch to 1 inch depending on the home's fixture count and demand. We assess your household's needs and install the appropriate size. Under-sized lines are a common source of chronic low pressure — getting the size right matters.
We work with copper and HDPE depending on the application and your preference. Both are durable in Phoenix conditions when installed correctly.

Yes. Water line work requires a permit in Phoenix metro municipalities. We handle the permitting process. Don't allow unlicensed work on your main water supply line — it affects your homeowner's insurance and creates liability.
