Repiping an older Southwest Florida home: when it is time and what to expect

A leak behind a wall gets fixed. A second one a year later gets fixed. Somewhere around the third, in a house built before the mid-1990s, the question changes from “where is this one” to “how many more are coming.” A whole-house repipe is the answer to the second question, and it is a larger, calmer job than most people expect.

Signs it is time to repipe

• Repeat leaks in different places. One pinhole is a repair. Pinholes in the kitchen wall, then the master bath, then the garage means the pipe itself has reached the end, not one spot on it.
• Polybutylene. Gray plastic supply pipe, common in homes built from the late 1970s through the mid-1990s, fails at the fittings and from the inside as chlorine breaks it down. It is replaced on sight, before it leaks, and many insurers will not write a policy with it in place.
• Galvanized steel. In pre-1970s homes, galvanized pipe rusts from the inside until the opening is the size of a pencil. Low pressure all over the house, with the utility saying the meter is fine, is the classic sign.
• Rusty or discolored cold water. Rust in the hot water alone points at the water heater. Rust in the cold too points at the pipe.
• Copper with green stains and crust at the joints, or pinholes along the bottom of horizontal runs. Our water chemistry is hard on copper, and a slab home has copper under the floor where you cannot see it fail.

What a repipe is, and what it is not

A repipe replaces the pressurized supply system: every hot and cold line from the main shutoff to each fixture, plus the shutoff valves at each fixture and the connections to the water heater. Often it includes a new main shutoff and hose bib connections.

It does not include the drains, the sewer line, or the vents. Those carry water away by gravity and are a separate system with separate materials and separate failures. In an older Fort Myers or Cape Coral home, cast iron drains may be failing at the same time as the copper supply, and the two are planned as two jobs, sometimes together.

PEX or CPVC?

Both are approved, both are used here, and both outlast what they replace.

• PEX is flexible tubing that runs in long pieces with few joints, bends around corners, tolerates freezing better than rigid pipe, and does not corrode. It goes in with crimp or expansion fittings and is the default for most repipes today.
• CPVC is rigid cream-colored plastic pipe, joined with solvent cement. It has been in Florida homes since the 1980s, works well, and is sometimes the better fit where a line has to run straight and exposed. Old CPVC gets brittle with age and heat, which is why some 1990s homes are being repiped now.

A good estimate names the material and the fitting system. Either answer is fine; “we will see” is not.

How the work goes in a slab home

There is no basement or crawl space here, and the old lines are usually in the slab or in the block walls. Nobody breaks up the floor. The new lines go up through the wall at the water heater and run through the attic, then drop down inside the walls to each fixture. To make those connections, the crew opens drywall at each fixture location: behind the shower valve, under the sinks, behind the toilets, at the washer box, and at the water heater. The openings are kept as small as the work allows and are patched after inspection.

The old pipe is cut, capped, and left in the wall or the slab. Insulation in the attic gets moved and put back. Expect a few days of dust covers and open walls, and expect the crew to test the whole system under pressure before the drywall closes.

Permits, inspections, and living through it

A whole-house repipe is permitted work in Lee and Collier County. The plumber pulls the permit, an inspector looks at the new lines before the walls are closed, and a final inspection follows. The permit is your record that the work was done to code, and it is what an insurer or a buyer will ask about later.

Water is off while the crew is connecting, usually most of one working day on a single-story home, and back on each evening. Most families stay in the house. Bathrooms work at night. The kitchen works at night. What you need is a plan for the days the walls are open: where the pets go, what furniture gets covered, and who is patching and texturing the drywall when the inspection passes. Your estimate should say whether patching is included, and to what stage: taped and mudded, or textured and ready for paint.

Insurance, the 4-point inspection, and why this is a licensed job

If your home is more than a few decades old, your insurer has probably already asked for a 4-point inspection, and plumbing is one of the four points. The inspector notes the supply material and its condition, and polybutylene, galvanized, and visibly corroded copper are the items that trigger a “replace before we bind” letter. A permitted repipe with a final inspection is the document that closes that loop. Whether a particular carrier offers a discount afterward is a question for the carrier; what we can say is that a repipe is what they ask for.

A repipe touches every fixture in the house, the water heater, and the main. It requires a permit and inspections, it involves attic work in a hot Florida summer, and a bad joint hidden in a wall shows up as a ceiling stain months later. This is not a place for a handyman or a weekend project. Ask for the license number, the permit, and the inspection schedule in writing.

If your home has had more than one supply leak, or an inspector has named the pipe material, send us the year the house was built, the material if you know it, and a photo of the pipes at the water heater. We will tell you whether a repipe is the right next step or whether a targeted repair still makes sense.
