Plumbing help in Arizona's Valley of the Sun
Caliche Plumbing connects homeowners across the Phoenix metro in Maricopa County with independent, licensed plumbers. The Valley's plumbing problems are distinct: some of the hardest water in the country, homes built on concrete slabs, long hot summers, and a housing boom that left many homes with polybutylene or aging copper.
Housing stock
Central Phoenix, Tempe and parts of Glendale and Mesa hold mid-century ranch homes with galvanized supply lines and cast iron drains. The 1978–1995 boom across Mesa, Glendale, Peoria, Sun City West and Phoenix put polybutylene in many homes. Most of the West Valley, Surprise, Goodyear and Gilbert was built after 1995 with copper or PEX. Almost all of it sits on slab foundations.
Water and utilities
Most Valley cities run their own water utilities, blending Salt and Verde river water, Colorado River water delivered by the Central Arizona Project, and groundwater. EPCOR and Liberty Utilities serve some communities, including Sun City, Sun City West and Litchfield Park. Hardness varies by source and season but is high almost everywhere. Southwest Gas serves most of the metro, and parts of Mesa are served by the City of Mesa's own gas utility.
Permits and licensing
Cities and towns issue plumbing permits for their own residents. In unincorporated areas such as Sun City, Sun City West and New River, Maricopa County handles permits and inspections. Plumbing contractors are licensed by the Arizona Registrar of Contractors (ROC), and anyone can look up a license on the ROC website.
Climate
Summer heat stresses water heaters in garages and attics, cooks exposed irrigation lines, and makes outdoor hose bibs deliver scalding water. Hard freezes are rare, but a few winter nights in the 20s can crack exposed backflow assemblies and pool equipment plumbing.
