The Orlando Homeowner’s Plumbing Guide

Living in Central Florida comes with a unique set of plumbing challenges — chlorinated municipal water, sandy soil, high summer attic temperatures, and homes built on concrete slabs. Understanding how your plumbing system works and how to spot problems early can save you thousands of dollars in water damage. This guide covers the pipe types you’ll find in most Orlando-area homes, the common failure points we see every week, and what to do about them.

Central Florida’s Potable Water System

Orange County supplies potable water from an underground reservoir called the Floridan Aquifer. It’s primarily fed by rainwater and filtered by sand and rock in a natural filtering process. According to the county, it needs little or no treatment other than disinfection and aeration to remove hydrogen sulfide.

The disinfection is done by adding chlorine to the water — and while that keeps the water safe to drink, it’s hard on your plumbing. Chlorinated water aggressively attacks metal pipes and certain plastics, cutting the service life of your distribution system and fixtures. Combined with the naturally “hard” mineral content of Florida groundwater, this is the number one reason we see so many premature pipe failures in the Orlando area.

A whole-home water filtration system and a water softener together can dramatically extend the life of your pipes, water heater, dishwasher, and ice maker.

Polybutylene (Poly-B) Pipes

Between roughly 1978 and 1995, polybutylene pipe was installed in millions of American homes, including many in the Orlando area. It’s no longer allowed by plumbing code and hasn’t been manufactured for U.S. residential plumbing since 1995. The reason: chlorine in municipal water reacts with the pipe walls, causing them to become brittle and crack from the inside out. Failures are often sudden and can cause catastrophic water damage.

If your home was built during that window and you still have gray or blue plastic pipe with copper crimp rings, you likely have poly-B. Insurance companies increasingly refuse to cover poly-B leaks, and some won’t insure the home at all until it’s repiped.

Copper Pipes and Slab Leaks

Most homes in the Orlando area have copper pipes that run under the concrete slab. Copper used in under-slab construction is Type M soft copper — it comes on a roll and doesn’t hold up well in Florida soil. We see the vast majority of failures on the hot-water side, where heat accelerates the chemical reaction between chlorinated water and the copper wall.

How to Check for a Slab Leak Yourself

If you suspect a slab leak, here’s a simple test any homeowner can do:

1. Turn off every fixture in the home — sinks, tubs, dishwasher, ice maker, irrigation, and toilets.
2. Walk out to your water meter. Most Orlando meters have a small triangle-shaped leak indicator that spins when water is flowing.
3. If the triangle is moving at all — even slowly — water is flowing somewhere.
4. Put a piece of painter’s tape next to one of the triangle’s points and mark it with a pen. Wait 15–20 minutes and check again. Any movement means a leak.

If the indicator is spinning and you’re certain all water is off inside the house, there’s a strong chance you have a slab leak. A slab leak can be spot-repaired, but we don’t recommend it — once one pinhole appears, others usually follow within months. The correct long-term fix is a whole-house re-pipe.

Other Warning Signs of a Slab Leak

• Warm or hot spots on the floor
• Higher-than-usual water bills
• Sudden drop in water pressure
• The sound of running water when everything is off
• Cracks appearing in interior walls or the slab itself
• Mold or mildew smell coming from baseboards

CPVC Pipes

CPVC is a rigid tan-colored plastic pipe that was widely used in Florida in the 1990s and 2000s. It handles chlorine better than copper or poly-B, but it becomes brittle over time. In a Florida attic, summer temperatures regularly hit 140–180°F, and that thermal cycling stresses the plastic. Older CPVC often cracks at fittings, at bends, or right through the pipe wall — sometimes decades before it’s supposed to.

If you have CPVC and you’re seeing small drips at joints, hairline cracks in visible pipe sections, or discoloration, it’s worth having it inspected before a small drip becomes a burst pipe.

Why PEX Is Our Recommended Replacement

For a whole-home re-pipe in the Orlando area, we recommend PEX Type-A with cold-expansion fittings. PEX has been used in Europe since the 1960s and in the U.S. since the 1980s. Its advantages for a Florida home:

• Chlorine resistant — won’t degrade like poly-B or corrode like copper
• Scale resistant — smoother interior wall than metal pipe
• Heat and freeze tolerant — expands and contracts without cracking
• Fewer fittings — flexible tubing means fewer joints and fewer failure points
• Quieter — absorbs water-hammer noise better than copper

When Should You Re-Pipe Your Home?

You don’t always need to wait for a catastrophic failure to consider a re-pipe. Consider one if:

• You’ve had two or more leaks in the past year
• You have polybutylene pipe of any age
• You have Type-M copper under a slab and the home is 20+ years old
• Water pressure has noticeably dropped throughout the house
• Water has a persistent metallic taste or rust-colored tint
• You’re selling the home and want to remove poly-B from the disclosure

Common Plumbing Questions from Orlando Homeowners

How long do copper pipes last in Florida?

In the Orlando area, Type-M soft copper under the slab often starts failing at 15–25 years. The hot-water side typically goes first. Homes built in the 1990s and early 2000s are hitting that window now.

Is a slab leak covered by homeowner’s insurance?

Most policies cover the resulting water damage but not the pipe repair itself. Policies vary widely. Get in writing what your carrier covers before you file.

Can I patch a slab leak instead of re-piping?

Yes, but it’s usually a bad investment. Once one section of Type-M copper fails, other sections are typically close behind. A spot repair buys months, not years. A full re-pipe reroutes water lines through the attic and walls, eliminating the slab as a failure point entirely.

Do I need a permit to re-pipe my home in Orange County?

Yes. All whole-home re-pipes in Orange County and the City of Orlando require a permit and inspection. We handle the permitting on every job we do.

How long does a re-pipe take?

A typical single-family home takes 1–2 days for the pipe work itself, plus drywall repair. The water is off for only a few hours during the changeover.
