Centennial Hills is the northwest growth area of the City of Las Vegas, built mostly from the 1990s through the 2010s as slab-on-grade, largely two-story tract homes under HOAs, plumbed with copper or PEX and now reaching equipment replacement age.
Centennial Hills runs from the Moccasin Road alignment south to Cheyenne Avenue and from Decatur Boulevard west toward the Red Rock preservation area, crossed by US 95 and the 215 Beltway. It is the newest large residential area inside the City of Las Vegas, built out mostly from the 1990s through the 2010s as master-planned and production tract housing. That means slab-on-grade homes, many of them two stories, with copper or PEX supply lines and ABS or PVC drains. There is no galvanized steel or cast iron to replace here. What wears out is the equipment and the fittings that went in with the house, now twenty to thirty years old.
Pipe and fixture services in Centennial Hills cover whole-house repiping, fixture installation and repair, remodel plumbing, backflow testing, and new construction and ADU plumbing. What makes this work distinct in Centennial Hills is that the housing stock runs from the 1990s through the 2010s, so the pipe itself is rarely the problem. Instead, fittings, valves, cartridges and equipment are reaching the end of their service life in water that measures about 280 parts per million, roughly 16 grains per gallon, and scale is the force behind most fixture and valve failures here.
Irrigation backflow assemblies installed with homes built in the 1990s and 2000s are now 20 to 30 years old. Pressure vacuum breakers and double-check valves of that age are common candidates for failed annual tests, and a cracked body or seized test cock after years of hard water and temperature cycling means repair or replacement before the assembly can be certified. Testing runs through the Las Vegas Valley Water District's backflow program, not the city building department.
Bathroom and kitchen remodel plumbing in Centennial Hills two-story homes means working around slab-on-grade construction on the ground floor and floor-ceiling assemblies above. Moving a drain on the ground level requires cutting the slab, and caliche beneath the slab makes that excavation slower and harder to bed new pipe into evenly. Permits and inspections for rough-in run through the City of Las Vegas building department under the 2024 Uniform Plumbing Code with Southern Nevada Amendments, effective January 5, 2026.
Shower mixing valves and faucet cartridges in homes of this age fail earlier than their rated life when scale from 16-grain water narrows the internal passages. A fixture installation or repair call in Centennial Hills often involves cleaning or replacing a cartridge that has been fouled rather than worn mechanically. Homes with an unused softener loop in the garage are running every fixture on untreated water, which accelerates the interval between cartridge replacements.
New construction and ADU plumbing in Centennial Hills requires tying into an existing sewer lateral and water service sized for the original house. Before framing starts, the length of the underground run from the new unit to the existing lateral matters for cost, and caliche hardpan makes that trench slower and more expensive to cut than softer ground. HOA architectural approval may also be required for any exterior utility connections visible from the street.

Local Knowledge
Even after a fixture installation in Centennial Hills, aerators and showerheads can clog with calcium deposits within months on untreated 16-grain water. A home with an unused softener loop in the garage is running every new fixture on hard water from day one, shortening the interval before the next service call. Pointing out the loop and discussing treatment at the time of installation is more useful than a return visit for a blocked aerator.
Kitchen or bathroom remodel plumbing that moves a drain on the ground floor of a slab-on-grade Centennial Hills home requires cutting the concrete. Caliche beneath the slab makes the excavation slower and harder to bed new pipe into evenly than softer ground would be. Budgeting for slab cutting and proper backfill is part of an honest remodel plumbing estimate here, not an unexpected add-on.
Most Centennial Hills homes sit under HOA architectural standards that govern exterior appearances. A new exterior tankless unit, a visible treatment system on a side yard, or any equipment mounted on a street-facing wall may require architectural approval before installation. Association approval and a City of Las Vegas permit are separate tracks, and skipping the HOA step can require relocating equipment after the fact.
ADU and casita plumbing in Centennial Hills requires trenching to connect a new unit to the existing sewer lateral and water service. Caliche hardpan makes that trench slower and more expensive to cut than softer ground, and the longer the run from the new unit to the existing lateral, the more that difficulty affects the overall cost. Confirming the run length and soil conditions before finalizing a budget is a practical first step.
Tankless water heaters are a common upgrade in Centennial Hills homes of this age, but at roughly 16 grains per gallon, a tankless unit without a treatment plan or regular descaling will see performance drop and the warranty position weaken. Descaling typically runs $150 to $250 in the Las Vegas Valley. Discussing a maintenance interval at the time of installation is more useful than addressing a fouled heat exchanger later.
What we offer in Centennial Hills
When the supply pipe in a home is failing everywhere at once, spot repairs only buy time. Active Plumbing replaces the water lines in Las Vegas Valley homes from the main shutoff to every fixture, using PEX or copper installed to the local code. We confirm what pipe you have on site, handle the permit, and give you a written price before work starts.
Learn more →Fixtures are the parts of your plumbing you use every day, and in the valley's very hard water they wear out sooner than people expect. Active Plumbing repairs and replaces faucets, toilets, shower valves, sinks, garbage disposals and appliance connections, and our trucks carry common repair parts so many jobs finish in one visit. You get a written price before work starts.
Learn more →A remodel is the one time the walls and floor are open, so it is the right time to get the plumbing behind them right. Active Plumbing plans and installs new drain, vent and supply lines, works through rough-in inspection with the building department for your address, and sets the finished fixtures. You get a written price before work starts.
Learn more →A backflow assembly keeps water from your irrigation system or building from flowing back into the public supply. In the Las Vegas Valley these assemblies must be tested by a certified tester at installation, after repair or relocation, and at least once a year. Active Plumbing handles the test, the repair and the replacement, with a written price before work starts.
Learn more →A new building or accessory unit gets its plumbing in stages, and each stage has to land at the right point in the schedule. Active Plumbing handles the underground, the rough-in and the trim for new homes, casitas and ADUs across the Las Vegas Valley. You get a written price before work starts, and we work alongside your builder or general contractor.

You get a written price covering PEX or copper and wall openings, and we file the permit with the building department for your address.
New lines run from the main shutoff to each fixture, with water restored at the end of each working day where possible.
The new system is pressure tested and inspected before walls close, then fixtures are reconnected and checked.

Local Tips
If a remodel will move a drain on the ground floor of your Centennial Hills home, ask for the slab-cutting and backfill cost as a line item before work starts, not as a change order after the concrete is already open.
Before an ADU or casita plumbing estimate is finalized, ask the plumber to walk the yard and note the distance from the new unit to the existing sewer lateral. That run length, combined with caliche hardpan, is the biggest variable in underground cost.
Schedule your irrigation backflow test before the watering season starts. Assemblies in Centennial Hills homes are now 20 to 30 years old, and a failed test followed by a repair and retest takes longer than a passing test alone, which can delay irrigation startup.
If you are adding a tankless water heater, confirm a descaling interval with the installer before the unit goes in. In 16-grain water, skipping maintenance shortens the life of the heat exchanger and can affect the warranty.
When planning a bathroom or kitchen remodel, confirm your City of Las Vegas permit is pulled before rough-in begins. Centennial Hills is inside the city, not unincorporated Clark County, so the permit counter, inspection schedule and applicable code edition are all city-specific.

Real reviews from Centennial Hills and nearby Las Vegas neighborhoods.
The ADU over the garage had no wet walls when we bought the lot. They tapped the main, set a cleanout, and plumbed every fixture. That call was from Centennial Hills. The ADU got a C of O without a punch-list on piping.

The hall bath faucet leaked at the base and stained the vanity. Cartridge, supply stops, and a new escutcheon, not a full remodel. We were in Rancho Bel Air, Las Vegas. The wood dried and we kept the stone top we liked.

Centennial Hills is inside the City of Las Vegas, so permits and inspections go through the City of Las Vegas building department under the Uniform Plumbing Code with the Southern Nevada Amendments. Some growth areas just north and west are unincorporated Clark County, so we confirm the authority for your exact address.
Tank water heater installation typically runs $800 to $1,500 in the Las Vegas Valley, and tankless water heater installation typically runs $1,500 to $3,500. These are typical valley ranges, not a quote. Active Plumbing gives a written price on site before any work starts.
Active Plumbing is open 24/7, and technicians arrive in 30 to 60 minutes anywhere in the valley, including Centennial Hills, Skye Canyon and Lone Mountain. Call (702) 438-3357.
Many Centennial Hills homes were built with a stubbed softener loop in the garage because the builder expected owners to add treatment. If nothing is connected, every fixture and appliance in the house runs on untreated very hard water. A softener or conditioning system can be connected to that loop, and our Water Treatment team can explain the options.
Interior work generally does not. Most of Centennial Hills is under associations governed by NRS Chapter 116, and their architectural rules cover exterior appearance, so an exterior tankless unit, a visible treatment system in a side yard or a new heater enclosure may need approval. That is separate from any city permit.
Start with the water heater and its expansion tank, the pressure regulator on the incoming service, and the original angle stops, supply connectors, toilet fill valves and washing machine hoses. In a two-story home, confirm the main shut-off actually closes and consider a pan under an upstairs washer.
Angle stops, toilet fill valves and supply connectors that are original to a 1990s or 2000s build are the highest-priority items in a two-story home, because a failure upstairs reaches the rooms below. Braided stainless connectors rather than original plastic ones, and a drain pan under an upstairs washing machine, are proportionate steps. A plumber can check shutoff valve condition and connector age in a single visit.
Rarely. Centennial Hills homes were built with copper or PEX supply lines, not polybutylene or galvanized steel, so the pipe material itself is not the problem a repipe solves. A repipe conversation here is more likely to come from an under-slab failure where rerouting the line is the better option than breaking the slab, or from documented widespread fitting damage. A site visit is the only way to confirm what the supply lines actually are and whether a repipe is warranted.
A failed test means the assembly cannot be certified until the defective component is repaired or the device is replaced and retested. Common failures in assemblies of this age include cracked bodies and seized test cocks. Under the 2024 Southern Nevada Amendments, a certified tester must leave certification on site after any repair or replacement. Active Plumbing can repair or replace the assembly and retest it in the same visit where parts allow.
