PEX Repiping Service
Call Now (855) 557-9600
PEX repiping services replace failed polybutylene, corroded galvanized steel, and brittle CPVC with cross-linked polyethylene tubing that routes through existing wall cavities with fewer access cuts than rigid pipe, resists scale and corrosion throughout its 40-plus-year service life, and costs less to install than copper at comparable performance. Bonded Plumbworks’ licensed plumbers design either a manifold home-run layout for individual fixture control or a trunk-and-branch configuration, then connect all runs with expansion fittings (PEX-A), crimp rings (PEX-B), or push-fit connectors per International Plumbing Code standards. PEX now represents over 60 percent of residential water supply installations in new construction nationwide, according to the Plastic Pipe and Fittings Association.
PEX repiping is the complete replacement of a home’s water supply piping with cross-linked polyethylene tubing, a flexible thermoplastic material rated for hot and cold water distribution at pressures up to 160 PSI at 73 degrees Fahrenheit. PEX eliminates corrosion-related failures and reduces the number of joints required compared to rigid pipe systems. — Bonded Plumbworks
PEX has been approved for residential plumbing and is one of the most widely installed supply materials in new construction nationwide. Its flexibility allows long continuous runs with fewer fittings, reducing potential leak points.
What Is PEX Repiping
PEX repiping involves removing the home’s existing supply lines and replacing them with PEX tubing connected via expansion fittings (PEX-A), crimp rings (PEX-B), or push-fit connectors. PEX is manufactured in three types: PEX-A (Engel method, most flexible), PEX-B (silane method, most common), and PEX-C (electron beam method). Dual-certified PEX-B from Zurn meets both ASTM F1807 crimp and ASTM F1960 expansion standards, giving PEX repiping installers the flexibility to use either connection method with a single tubing product. All three types meet ASTM F876/F877 standards for potable water distribution.
Cross-linked polyethylene achieves its durability through molecular cross-linking — chemical bonds formed between polymer chains that give PEX its shape memory, thermal resistance, and pressure-bearing capacity. PEX-A has the highest degree of cross-linking at 70 to 80 percent, providing superior flexibility and freeze resistance. — Bonded Plumbworks
PEX systems often use a manifold (home-run) layout where individual lines run from a central manifold to each fixture, eliminating tee connections and allowing individual fixture shut-off at the manifold location.
When to Schedule PEX Repiping
PEX repiping replaces failed polybutylene, corroded galvanized steel, and brittle CPVC with a flexible cross-linked polyethylene system at lower installed cost than copper.
Consider PEX repiping when the following conditions exist:
- Polybutylene supply lines require replacement due to known material defects
- Galvanized steel pipes have corroded internally, restricting water flow
- Multiple pinhole leaks in copper indicate aggressive water chemistry
- CPVC pipe has become brittle with failing fittings
- You want a cost-effective repiping solution with fast installation
- Water pressure has dropped at multiple fixtures throughout the home
- Your insurance carrier requires repiping to maintain coverage
- Partial repiping targets the most deteriorated sections first when budget constraints prevent a full PEX repiping — though transition fittings at old-to-new junctions require dielectric isolation to prevent galvanic corrosion at the connection points
- New construction or major renovation calls for a modern supply system
The Plastic Pipe and Fittings Association (PPFA) reports that PEX represents over 60 percent of residential water supply installations in new construction across the United States.
How PEX Repiping Works
Step 1: System Design and Layout
Our plumber maps the existing supply system and designs the PEX replacement layout. We offer two configurations: traditional trunk-and-branch (similar to existing pipe routing) and manifold home-run (individual lines from a central manifold to each fixture). The home-run layout eliminates tee connections and delivers more consistent pressure across fixtures because each line runs independently from the manifold, while trunk-and-branch PEX repiping uses fewer materials but shares flow capacity among downstream fixtures. We recommend the best layout based on your home’s structure and your performance goals.
Step 2: Manifold or Trunk Line Installation
For manifold systems, we install a PEX manifold with individual shut-off valves in a central location (typically the garage or utility room). PEX-A tubing such as Uponor AquaPEX meets ASTM F876 and F2023 standards with the highest crosslink density, and PEX repiping with PEX-A provides superior freeze resistance and the strongest expansion-fitting joints available. For trunk-and-branch systems, we install the main trunk lines along the primary pipe routes. PEX flexibility allows routing through existing wall cavities with minimal new access openings.
Step 3: Branch Line Routing
Individual PEX lines are run from the manifold or trunk to each fixture, appliance, and outdoor connection. PEX bends around corners without requiring elbow fittings, reducing connection points and potential leak locations. We use proper support clips at code-required intervals and allow expansion loops where PEX transitions through framing. Foam pipe insulation wraps PEX runs in unconditioned spaces to prevent heat loss on hot lines and condensation on cold lines, and PEX repiping through attics requires UV-resistant insulation to protect the polymer from sunlight exposure near gable vents.
Step 4: Connection and Fitting Installation
Clamp (cinch) rings conforming to ASTM F2098 use a stainless steel ring compressed by a ratcheting clamp tool to secure PEX connections, offering a cost-effective alternative to crimp rings during PEX repiping. All connections are made using the appropriate method for the PEX type — expansion rings for PEX-A, crimp rings for PEX-B, or push-fit connectors for transitions. Expansion connections provide the strongest joint because the fitting is compressed inward by the PEX’s shape memory. Crimp rings with a dedicated crimping tool conforming to ASTM F1807 create permanent joints on PEX-B tubing by compressing a copper ring around the pipe and fitting, and PEX repiping crews calibrate the crimping tool before each job to ensure consistent ring compression. We use brass or PPSU (polyphenylsulfone) fittings meeting NSF/ANSI 61 certification.
Step 5: Pressure Testing and System Activation
We pressurize the complete system to 150 percent of operating pressure and hold for a minimum of two hours. After confirming zero pressure loss, we connect all fixtures, flush the system, and verify pressure and flow at every outlet. We test hot water delivery time at the farthest fixture to confirm optimal performance.
Benefits of PEX Repiping vs Copper and CPVC
PEX offers several advantages over rigid pipe materials. Its flexibility reduces the number of fittings needed, lowering both installation cost and potential leak points. PEX expands up to three times its diameter before bursting, providing superior freeze resistance — a significant advantage during the area cold fronts. PEX does not corrode, scale, or develop pinhole leaks from aggressive water chemistry.
Installation is faster than copper or CPVC because PEX requires no soldering, solvent welding, or cure time. The manifold layout option provides individual fixture isolation without cutting into walls to access shut-off valves. PEX material costs approximately 60 to 70 percent less than copper and comparable to CPVC. PEX-B tubing from manufacturers like Viega, SharkBite, NIBCO, and Zurn offers the widest product availability and the lowest material cost per foot for PEX repiping, though its insert fittings slightly reduce internal bore diameter compared to PEX-A expansion connections.
The primary trade-off is that PEX cannot be used outdoors where exposed to UV light (sunlight degrades the polymer) and has a shorter proven track record than copper. PEX carries a 25-year manufacturer warranty, with expected service life extending well beyond that under normal conditions.
Bonded Plumbworks also offers partial repiping for homeowners who need comprehensive plumbing solutions beyond standard pex repiping.
Pricing for PEX Repiping
PEX repiping is the most cost-effective whole-house repiping option in both material and labor. Pricing depends on the home’s square footage, fixture count, system layout (manifold vs trunk-and-branch), and access complexity. Drywall cut and patch after a PEX repiping project is typically quoted separately from the plumbing work, adding $50 to $90 per square foot for a professional drywaller to follow behind the plumbers. Manifold systems cost slightly more in material but save labor through simplified routing.

Frequently Asked Questions
Is PEX safe for drinking water?
Yes. PEX is certified by NSF International under NSF/ANSI Standard 61 for potable water contact. All PEX tubing used in residential installations meets strict requirements for chemical leaching at residential water temperatures. PEX is approved for potable water use by all major building codes in the United States.
How long does PEX piping last?
PEX carries manufacturer warranties of 25 years with expected service life of 40 to 50 years under normal conditions. Independent testing by the Plastic Pipe and Fittings Association projects PEX longevity at 100 years or more when installed correctly and operated within rated temperature and pressure parameters. PEX-C tubing uses electron-beam irradiation for crosslinking and has a lower crosslink density than PEX-A or PEX-B, making it less common in PEX repiping but still suitable for straight-run applications where flexibility is not a primary requirement.
Can PEX be used for both hot and cold water?
Yes. PEX is rated for both hot and cold water distribution. Standard PEX is rated to 200 degrees Fahrenheit at 80 PSI. Color coding is used for identification — red for hot water lines, blue for cold, and white for either — but all colors have identical material properties and ratings.
How much does pex repiping cost?
PEX Repiping typically costs $2,500 to $7,000 for a whole-house PEX repipe depending on home size. The final price depends on the scope of work, accessibility, and materials required.
