Slab Leak Detection and Repair in Glendale, AZ

Split between SRP and CAP

Glendale draws on both big canal systems almost equally. Its 2024 water quality report gives the mix as 46 percent SRP water from the Salt and Verde, 43 percent CAP water from the Colorado, 5 percent groundwater and 6 percent reclaimed water for non-drinking uses. The 2023 report, the most recent with a hardness table, put hardness at 8.9 to 18.1 grains per gallon, averaging 13. The 2024 report adds that hard water can lead to scaling in pipes and water heaters. The city’s system includes about 65,000 service lines and more than 1,100 miles of pipe, and everything past your meter is your side of that network.

Catlin Court to Arrowhead Ranch

Glendale is one of the older towns in the Valley. William John Murphy laid it out after finishing the Arizona Canal in 1885, and the Catlin Court historic district downtown was built between roughly 1914 and 1942, much of it in Craftsman bungalows. In a house that old we never assume the plumbing is original, and we check what is actually there before planning any access. Arrowhead Ranch, in the north near Loop 101, was acquired for development in 1978 and annexed in 1979; its houses are slab-built suburban stock from the decades that followed, a completely different starting point for a leak search.

Older homes, older drains

In the older parts of the city, a leak under the house can just as easily be on the waste side as the supply side, and the signs overlap: a damp baseboard, a smell, a slow drain. We run pressure and acoustic testing on the supply lines and a camera through the drains before deciding. Broken or bellied waste pipe under the slab calls for under-slab drain repair. A house whose original supply piping keeps failing is a candidate for a whole-house repipe.

West Valley neighbours

Glendale sits between Phoenix and Peoria, and we cover both from the same side of town.
