Leak Detection & Repair in Reunion, Commerce City, CO

Reunion is Commerce City's largest master-planned community, developed from the early 2000s on the northern side of the city. The housing here is modern: slab-on-grade construction, PEX cross-linked polyethylene supply with manifold distribution, and PVC drain systems. The plumbing failure profile in Reunion is completely different from the historic-core neighborhoods. Instead of corroding galvanized pipe, Reunion homes fail at mechanical fittings, at PEX manifold connections, and at the slab penetration points where supply lines enter the living space through the concrete.

Reunion homes built between 2003 and 2012 used PEX supply with crimp-ring fittings at the manifold. Early-cohort fittings in high-cycle environments show higher failure rates than later installations, and Reunion homes built before 2009 are now reaching the 15-to-20-year age range where these early manifold connections begin to show failures. A leak in a Reunion home often presents as a warm patch on the slab floor from a hot-water supply line failure, or as a fitting failure at the manifold box that is accessible in a utility closet without any wall demolition.

Plumbing Profile in Reunion

Slab-on-grade construction means the supply lines are embedded in or run beneath the concrete slab. A slab leak in Reunion is detected by pressure testing to isolate the compromised circuit, thermal imaging to map the warm zone from a hot-water line failure, and tracer gas where the PEX material attenuates acoustic signals before they reach the slab surface. Reunion's Adams County clay soil heaves with seasonal moisture, applying mechanical stress to the slab-embedded supply lines at fittings and anchor points through each wet-to-dry cycle.

Reunion properties have two SACWSD meters: one for indoor potable supply and one for the SACWSD non-potable irrigation system. Underground leak symptoms in Reunion require identifying which meter is moving before detection equipment is dispatched, since the potable supply and the irrigation system are completely separate pipe networks with different materials and different detection methods. The non-potable irrigation laterals are polyethylene pipe traced by tracer gas; the potable supply is PEX traced by tracer gas or pressure-tested at the manifold.

Leak Detection & Repair Approach in Reunion

For slab supply failures, the detection sequence is pressure testing to isolate the circuit, then thermal imaging and tracer gas to pinpoint the fracture location before any core drilling. For manifold fitting failures, the manifold box access panel in the utility closet allows inspection of the connection points without wall demolition. For irrigation lateral failures, zone-by-zone pressure testing at the valve manifold isolates the failing zone and tracer gas locates the fracture. The post-2021 SACWSD water at 7 grains per gallon is well-suited to the PEX supply in Reunion homes, with minimal scale accumulation compared to the copper-supply tract homes elsewhere in Commerce City.

Leak Repair in Reunion

Repair for slab-embedded PEX failures in Reunion depends on what detection establishes. A single fitting failure at an accessible manifold connection is repaired at the manifold box in the utility closet without any slab or wall work. A slab fracture away from the manifold is repaired by core drilling a 4-inch access hole at the pinpointed location, replacing the failed fitting or section, and patching the concrete. When multiple PEX circuits show stress failures in a home with early-cohort 2003 to 2010 crimp-ring fittings, rerouting the supply lines above the slab through walls and ceilings removes the risk of repeat slab work entirely. Irrigation lateral failures on the SACWSD non-potable system are repaired by excavating a small access pit at the confirmed failure location and installing a mechanical coupling or replacing the lateral section.

Frequently Asked Questions

What causes leaks in Reunion Commerce City homes?

Reunion homes from the 2000s fail at PEX manifold fitting connections, at slab penetration points, and at slab-embedded supply line fittings stressed by Adams County clay soil movement. Early-cohort PEX manifold fittings from the 2003 to 2010 construction period are now reaching the 15-to-20-year age range where failures begin to appear. Irrigation lateral failures on the SACWSD non-potable system are also common.

Why does my Reunion home have two water meters?

Reunion properties have a SACWSD potable meter for indoor water supply and a separate SACWSD non-potable meter for the irrigation system. The two serve completely separate pipe networks. When a leak is suspected, checking which meter is moving identifies whether the failure is in the potable supply or the irrigation system, which determines the detection method.

Can a slab leak in my Reunion home be found without breaking the concrete?

Yes. Pressure testing isolates the compromised circuit, thermal imaging maps the warm zone from a hot-water line failure, and tracer gas locates the fracture through the slab aggregate. The leak is located to within about 6 inches before any core drilling. A targeted 4-inch core drill at the confirmed location is far less disruptive than exploratory slab cutting.
