Plumber in Cave Creek
Licensed plumbers for Cave Creek and Desert Hills homes, with the town's two water systems, septic rules and code cycle laid out from its own pages.
Plumbing in Cave Creek
Cave Creek is a small town of about 5,100 people, and 95 percent of its households own their home. Plumbing here depends on which side of the utility map you're on: the town runs two separate water systems, one fed by Colorado River water and one by groundwater, and its sewer system is, in the town's words, very limited in area. That leaves a lot of homes on septic. HQ Plumbing & Air covers Cave Creek around the clock, with upfront pricing and free estimates.

Two water systems, two different sources
The Town of Cave Creek runs two water systems. The Cave Creek Water System pulls raw Colorado River water from the Central Arizona Project canal at Deer Valley Road in Phoenix and pumps it about 12 miles through a 16-inch pipeline to the town's treatment plant on Basin Road. According to the town, it has had about 2,537 connections and delivered about 1,127 acre-feet of water in 2024. The town bought the system in 2007 and says it has relied solely on CAP surface water since, with no wells supplying drinking water today.
The Desert Hills Water System is different. The town says it draws groundwater from three wells and is solely dependent on a decreasing groundwater supply, so the town tops it up with treated CAP water through an interconnect. Desert Hills had 1,820 connections and delivered about 755 acre-feet in 2024. Between the two, the utility serves 4,357 connections, more than the roughly 2,860 homes the Census counts inside the town limits, so its service area clearly reaches beyond them. The town's water service area map, linked in the sources, shows which system your address is on.
The town's 2025 water quality reports for both systems list what was detected in testing, and neither one publishes a hardness number. They describe hardness as a harmless cosmetic effect, and hard water is known for scale in water heaters and fixtures. The USGS calls water above 180 milligrams per liter, about 10.5 grains per gallon, very hard. If you want your own number, the town's water line is 480-488-6620. The town's source water page also notes that while the town uses no wells for drinking water, many residents operate private wells, and a home on its own well isn't covered by the town's reports.
Sewer is limited, and septic answers to the county
The town's wastewater page says its sewer collection system is very limited in area and that not all areas can be served. As of July 2024 it counted 436 residential sewer connections, 336 multifamily, 134 commercial, 27 restaurants and 947 customers in all, against roughly 2,400 households in town. That suggests most homes are on septic tanks rather than town sewer. The town's treatment plant handles about 300,000 gallons a day, and the treated water goes to golf courses for irrigation.
Septic work isn't the town's to permit. Maricopa County's Environmental Services Department runs the onsite wastewater program, and its homeowner guide says applications are required for new septic systems, remodels of homes on septic, and alterations to existing systems. It also says any increase in the number of plumbing fixtures or bedroom equivalents can increase system demand and require county review, and that many building jurisdictions want county septic approval before issuing a building permit. Status questions go to the county at 602-506-6824. If you're adding a bathroom to a septic home, that county review comes before the plumbing.
Permits, codes and inspections in Cave Creek
The town's Building and Fire Code Compliance page says that as of January 1, 2026, permit applications follow the 2024 International Building, Residential, Plumbing, Mechanical, Fuel Gas and Fire codes, with the 2023 electrical code. Applications submitted under the 2021 cycle are evaluated case by case. Cave Creek amends those codes, and its town code covers a few rules worth knowing. An application is abandoned 180 days after filing unless it's pursued in good faith, and a permit lapses if work doesn't start within 180 days as shown by a passed inspection. Starting work on a plumbing or gas system before the permit costs an extra fee equal to the permit and plan review fee.
The town also posts inspection checklists. The plumbing final checklist says a gas water heater swap with no pipe changes is a mechanical inspection, while an electric water heater, or a gas one with pipe changes, gets a plumbing inspection. For water heaters the inspector looks for a relief valve drain that is air gapped, not trapped, and ends outside 6 to 24 inches above grade, a watertight pan with a 3/4-inch drain when the heater sits in an attic or above a floor, and hose bib pressure of 80 psi or less, or a pressure-reducing valve. The older checklist also lists expansion-tank checks for a closed system or main pressure above 120 psi. That wording does not replace its separate 80 psi pressure-reducing-valve limit. Confirm thermal-expansion control requirements under the town's current adopted code; the checklist also limits hot water at fixtures to 120 degrees.
For gas, the town's checklist says new or added piping is pressure tested at 1 1/2 times operating pressure, at least 3 psi, for 10 minutes minimum, and that defective piping is replaced, not repaired. The town's under-slab checklist says water service and sewer pipe are buried at least 12 inches outside the building, and the water meter can't be in the driveway. These checklists cite the 2021 IRC while the town's code cycle is now 2024, so treat them as a guide and confirm with the town. The permit technician is at 480-488-6622.
Cave Creek's homes: built up in the 1990s and 2000s
Census figures put the median home at 1998. About 27 percent of the roughly 2,860 homes date from the 1990s and about 45 percent were built since 2000. Only about 16 percent, around 450 homes, are older than 1980, and none in the survey date from before 1950. Renters are only about 5 percent of households. Homes this age usually have copper supply lines and may be on their second or third water heater, and a slow drain can be an in-house problem or a tank and leach field problem, so we work out which before we recommend anything.

What We Do in Your Area
How do I verify a plumber's license in Arizona?
Use the Arizona Registrar of Contractors free public license search at roc.az.gov/search. Look up the plumber by license number, business name, or qualifying-party name, then confirm the license is Active, the classification matches your job, the bond is current, and the complaint history is clean before you sign anything.

A slab leak can develop when a buried supply pipe corrodes, rubs against concrete or soil, or is stressed by ground movement, thermal expansion or excessive pressure. Water chemistry can contribute to copper pitting, but hardness alone does not identify the cause. Leaks beneath a slab can remain hidden.
