Water heaters, pressure regulators and original fittings in Centennial Hills homes built from the 1990s to the 2010s
Customer financing available. Ask us about options.
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.
Local Knowledge
Tanks installed with homes in the late 1990s and 2000s are at or past their rated life. Hard water scale on elements and tank bottoms means an unflushed heater fails earlier than its label suggests.
Thermal expansion tanks fail without obvious signs, often showing up as a dripping relief valve. Pressure regulators wear and either creep high, stressing fixtures, or drop and cause low pressure complaints.
Angle stops, supply connectors, fill valves and washer hoses are often original. In two-story plans, a failure in an upstairs bathroom or laundry sends water into the living space below.
At about 280 parts per million, roughly 16 grains per gallon, scale fouls tankless heat exchangers and the small passages in shower cartridges, so showers swing hot and cold and tankless output drops without regular descaling.
Copper and PEX of this age leak under the slab less often than older pipe, but it happens, often where a line was damaged during construction. Detection comes first, then the choice between opening the slab and rerouting the line.

What we offer in Centennial Hills
A softener is the only common home treatment that actually removes calcium and magnesium from your water. Active Plumbing sizes the unit to your household and hardness, installs it with a bypass, brine tank and properly discharged drain line, and sets the regeneration schedule before we leave. You get a written price before work starts.
Learn more →Whole-house filtration treats water where it enters the home, so showers, laundry and every faucet get filtered water. In the valley that usually means a sediment stage and an activated carbon stage to remove chlorine taste and odor. Active Plumbing designs the system around your water and flow, and gives a written price before work starts.
Learn more →Las Vegas Valley water is safe and treated, but it is very hard, and that shows up in taste, cloudy ice and scaled kettles. A reverse osmosis system at the kitchen sink removes most of the dissolved minerals from the water you drink and cook with. Active Plumbing installs the unit, the faucet, the drain connection and any ice maker line, and gives you a written price before work starts.
Learn more →Testing at the tap tells you two things the utility's own reports cannot: what your home's pipes add to the water, and how hard your water actually is at your address. Active Plumbing collects the sample following lab protocol, sends it to a certified laboratory and walks you through the report. If treatment would help, we tell you which kind, and if it would not, we say so.
Learn more →A salt-free conditioner does not remove the calcium and magnesium in valley water. It changes how those minerals behave so less of them sticks to pipes, heater tanks and fixtures as scale. Active Plumbing explains plainly what a conditioner will and will not do before you decide, and gives a written price before work starts.
Learn more →The water leaving the treatment plant is not always the water that reaches your glass. Lead and copper usually come from the plumbing inside a home - solder, brass fittings and corroding pipe - so the only meaningful test is one taken at your tap. Active Plumbing collects samples properly, has them analyzed by a certified laboratory and explains what the numbers mean for your plumbing.
Learn more →PFAS are measured in parts per trillion, so a reliable result depends on careful collection and a certified laboratory. Active Plumbing takes PFAS samples at your tap or well using the lab's containers and handling protocol, then walks you through each compound in the report. If treatment makes sense, we explain your options before anything is installed.
Learn more →Call (702) 438-3357. We confirm household size, hardness and whether there is a softener loop or the supply needs rerouting.
We recommend a unit capacity matched to your use and give a written price before work starts.
We tie in the softener with a bypass valve, set the brine tank and run the drain line to an air gap.
We program regeneration, check that treated water is soft, explain salt top-ups, and follow up after the job.

Local Tips
Find your main shut-off and test that it closes fully, since an upstairs leak in a two-story Centennial Hills home can reach the rooms below.
Swap any original plastic supply connectors for braided stainless ones and put a drain pan under an upstairs washing machine.
Check your association's architectural rules before mounting a tankless heater or treatment system on an exterior wall.

Real reviews from Centennial Hills and nearby Las Vegas neighborhoods.
A cracked yard hydrant was wasting water at the dog run. Frost-free hydrant on a new lateral with a drain gravel pit. We were in Scotch Eighty, Las Vegas. The run is dry except when we choose to water.

The upstairs shower went scalding when a toilet filled. A pressure-balance cartridge and new stops behind the trim. That call was from Westleigh. Kids can shower while someone flushes now.

The restaurant mop sink backed into the kitchen during a rush. Jet the grease line and reset the trap that had been skipped. That call was from Symphony Park. The line is on a 90-day pump schedule now.

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.
