Make Plumbing Problems Disappear - Fast

  • When a home inspector calls out “old pipes” or “low water pressure”, buyers panic and deals stall.

  • PEX PDX solves this with same-day whole-house repiping using durable PEX piping.

  • We specialize in turning a red flag into a selling point.

Step-by-Step Repiping Process

  • Initial Inspection and Assessment

    A licensed plumber conducts a thorough inspection of the property’s plumbing system to assess pipe conditions, identify problem areas, and determine the scope of the repipe.

  • Planning and Material Selection

    Based on the assessment, the plumber develops a repiping strategy and selects suitable piping materials (PEX, copper, or CPVC) tailored to the home’s needs and local codes.

  • Shutoff and Preparation

    The water supply is shut off, protective coverings are placed to safeguard floors and furniture, and access points to plumbing lines are prepared, often by cutting into walls, ceilings, or floors.

  • Old Pipe Removal

    Worn, corroded, or failing pipes are carefully removed. In some cases, old pipes may be left in place if they pose no interference and removal would cause excessive disruption.

  • New Pipe Installation

    New water lines are routed and installed, adhering to layout plans. Pipes are securely fastened and routed with minimal disruption to the structure.

  • Connection to Fixtures and Main Line

    New pipes are connected to all existing fixtures, such as sinks, toilets, showers, and water heaters, and tied into the main water supply and any auxiliary systems.

  • Pressure Testing and Inspection

    The new system is pressurized and inspected for leaks. Plumbers conduct flow tests to ensure proper water pressure and functionality before finalizing the project.

  • Wall Patching and Site Cleanup

    Any access holes are patched, walls repaired, and surfaces returned to their original condition. Debris is cleared, and the work area is left clean.

  • Final Walkthrough

    The plumber performs a final walkthrough, explains the new system layout if needed, and verifies customer satisfaction before closing out the job.

Return on Investment of Whole House Repiping with PEX Pipe

  • PEX repiping typically costs significantly less than copper installations while delivering superior performance and longevity. Material costs for PEX are substantially lower than copper, and installation time decreases due to PEX's flexibility and simplified connection methods. Our pricing reflects these material and labor savings, making whole-house repiping more accessible for homeowners. The investment pays dividends through reduced maintenance costs and improved water delivery throughout the home's lifespan.

  • Modern PEX plumbing systems represent a major upgrade that appeals to potential buyers and increases property marketability. Real estate professionals recognize updated plumbing as a key selling point that eliminates buyer concerns about costly future repairs. Our professional installations meet current building codes and provide documentation that supports higher property valuations. The investment typically recovers a substantial percentage of costs through increased home value and faster sales in competitive markets.

  • PEX systems deliver ongoing financial benefits through improved efficiency and reduced maintenance requirements compared to traditional materials. The smooth interior surfaces resist mineral buildup that restricts flow in older pipes, maintaining optimal pressure and reducing energy costs for water heating. Our installations eliminate the frequent repair calls associated with corroding galvanized or brittle polybutylene pipes, saving homeowners thousands in emergency service costs over the system's extended lifespan.
