Thinking about a PEX repipe? Here is what the project looks like from your side: whether your home is a good candidate, how the system is laid out and what happens day by day.
Deciding to replace your home’s water lines is a big step. Once you’ve settled on PEX, the next questions are practical: Will my walls be torn up? How long will the water be off? What exactly is getting replaced? This article walks through what installing a PEX plumbing system looks like for a typical Central Florida home, from deciding you need it to the final walkthrough.
If you’re still weighing PEX against copper or CPVC, our article on the benefits of PEX compared with other pipe materials covers that comparison in detail.
Is Your Home a Good Candidate?
A PEX repipe is worth considering when one or more of these is true:
- Your home has polybutylene, the gray plastic supply pipe common in homes built roughly from the late 1970s to the mid-1990s
- You have galvanized steel lines that produce rusty water or weak pressure
- Copper lines have had repeated pinhole leaks
- You’ve had more than one slab leak, and rerouting the lines overhead makes more sense than chasing repairs under the floor
- You’re planning a major remodel and walls will already be open
Not sure what’s in your walls? Our post on evaluating older pipe materials explains how to tell.
Choosing a Layout
Trunk and branch
This is the traditional layout. A main line runs through the house with tees branching off to each fixture. It uses less tubing and is familiar to inspectors and plumbers alike.
Home-run manifold
Each fixture gets its own line from a central manifold, often located in the garage or a utility closet. You can shut off a single fixture at the manifold, and pressure tends to stay steadier when several fixtures run at once. It uses more tubing but fewer hidden fittings.
Hybrid
Many repipes combine the two, with a manifold for bathrooms and branches for the kitchen and laundry, for example. Your plumber will suggest what fits your floor plan.
Rerouting Away From the Slab
In slab-on-grade homes, original supply lines often run under the concrete. During a repipe, PEX is usually routed through the attic and dropped down inside walls to each fixture. That means future leaks, if they ever happen, are reachable without breaking concrete. Old under-slab lines are abandoned in place. In a hot Florida attic, lines are typically insulated and kept clear of heat sources, and the plumber follows the manufacturer’s support requirements.
What the Process Looks Like
- Assessment and quote. The plumber walks the house, notes every fixture, checks attic access and explains the layout and price.
- Permits. A licensed contractor pulls the plumbing permit where required.
- Protecting your home. Floors and furniture near work areas are covered.
- Access openings. Small, neat cuts are made in drywall where lines need to drop to fixtures. PEX’s flexibility keeps these to a minimum.
- Running new lines. New tubing runs from the main supply to each fixture, with new shutoff valves at sinks and toilets.
- Connections. Lines are tied in at the water heater, typically with a short metal transition, and at the main.
- Pressure testing and inspection. The system is tested for leaks and inspected before walls are closed.
- Patching and cleanup. Openings are patched, and the work area is cleaned.
Living Through It
Most families stay home during a repipe. Water is typically shut off while the crew works and restored at the end of the day where possible. Expect some noise and a few patched spots that may need paint afterward. Ask your plumber up front whether drywall patching and texture are included.
After the Repipe
- New lines may have a faint plastic smell at first. Running each tap for a few minutes helps.
- Learn where the new main shutoff and any manifold valves are.
- Keep the permit and inspection records with your home documents. They’re useful when you sell or update insurance.
