We never cut corners with cheap crimp fittings or thin builder-grade tubing. Master Plumber Bill Clark exclusively installs premium Uponor PEX-A expansion systems and heavy-gauge Type L Copper.
Colorado's high elevation, freezing winter temperatures, and municipal water treatment additives demand piping materials that withstand intense hydraulic and thermal stress. Explore our primary piping standards below:
Our gold standard for whole-home residential repiping. Cross-linked polyethylene with thermal shape-memory expands safely if water freezes, while full-port ProPEX fittings deliver maximum water volume.
Compare chemical manufacturing, flexibility, and hydraulic flow. Learn why builder-grade contractors install cheap PEX-B crimp rings that choke shower pressure and restrict line volume by up to 30%.
Heavy-wall, commercial-grade rigid copper piping for exposed mechanical rooms, boiler circulation loops, water heater connections, and historic districts requiring all-metal construction.
| Material Parameter | Uponor PEX-A (Our Standard) | Standard PEX-B (Budget Grade) | Type L Copper (Our Metal Standard) |
|---|---|---|---|
| Fitting Method | ProPEX Full-Port Expansion | Internal Crimp Ring (Reduced Bore) | Soldered / ProPress Copper |
| Water Flow Volume | 100% Unrestricted Full Flow | 20–30% Pressure Choke at Fittings | 100% Full Bore Capacity |
| Freeze-Burst Resistance | Thermal Shape Memory (Expands & Recovers) | Prone to Splitting at Rigid Crimp Rings | Rigid Metal (Splits Seams When Frozen) |
| Corrosion / Pinhole Immunity | 100% Immune to Scale & Chloramines | Immune to Rust, Vulnerable at Brass Rings | Heavy Wall; High Pitting Resistance |
| Manufacturer Material Warranty | 25 Years | 10–25 Years (Varies by Crimp Maker) | 50 Years (Standard Industry Rating) |
Many low-bid repiping contractors cut corners by using PEX-B tubing secured with copper crimp rings. To make a crimp connection, an undersized fitting must be inserted into the pipe, creating a permanent 20% to 30% constriction at every single tee, elbow, and turn.
When multiple showers or fixtures run simultaneously, homes plumbed with PEX-B experience severe pressure drops. Just Plumbing exclusively installs Uponor PEX-A using full-port expansion rings that expand the pipe temporarily, allowing fittings with the exact same inner diameter as the pipe itself.
The result is 100% full water volume, whisper-quiet operation, and a plumbing system engineered to last for generations.
Our premium material upgrades permanently eliminate the risks associated with defective legacy plumbing across Front Range homes. Select your pipe problem below to view diagnosis and replacement protocols:
Uponor PEX-A utilizes the Engel-method cross-linking process, giving the pipe thermal shape memory. It expands with freezing water to prevent bursting, and connects with full-port expansion fittings that maintain maximum water volume. Cheaper PEX-B requires insert crimp fittings that restrict water flow by 20% to 30% at every joint.
Type L rigid copper is the ideal specification for exposed mechanical rooms, boiler loops, commercial risers, and historic homes where local architectural review boards or strict municipal building codes mandate metallic water lines.
Uponor PEX-A systems installed by Just Plumbing carry a 25-year manufacturer material warranty paired with our 5-year Master Plumber workmanship warranty.
