Yes, newer homes can get slab leaks. Most new builds use PEX supply lines, which resist corrosion, but leaks can still come from fittings, nail or screw punctures during construction, kinked or stressed pipe, and soil settling under a new slab. Watch for a moving meter, warm floor spots and unexplained bills, and check before your builder warranty period ends.
- New homes have fewer slab leaks, not zero.
- Fittings, construction damage and settling are the usual causes.
- Do a meter test in the first months, and again before the warranty ends.
- Document anything you find in writing for the builder.
Why New Homes Still Leak
Fittings and connections. PEX itself holds up well, but every crimp, clamp or expansion fitting is a point where a poor connection can weep.
Construction damage. A pipe nicked during the pour, or stressed where it rises out of the slab, can hold for months before it fails.
Settling. A new slab on fresh fill settles during its first wet and dry seasons. That movement can strain lines where they enter walls and fixtures.
Mixed materials. Some builds use copper stubs or older-style connections at the water heater and manifold, which bring their own risks.
Early Signs to Watch For
- The water meter moves with every fixture off
- A warm spot on tile or bare concrete
- Damp carpet edges or baseboards near bathrooms or the kitchen
- A water heater that seems to run more than it should
- A water bill higher than similar homes in your community

Check Before the Warranty Ends
Many new homes come with a builder warranty that covers plumbing for a period after closing. The terms vary by builder, so read yours. A simple plan is to do a water meter leak test a few months after moving in and again shortly before the plumbing coverage ends. If the meter moves, document it and contact the builder in writing. An independent leak detection report can help support a claim.
Tip: Keep a copy of your plumbing layout or manifold labels from the builder. It makes isolating a leak much faster.
Newer Communities Around Plant City
Communities such as Varrea and North Park Isle in north Plant City, and newer neighborhoods in southeast Plant City, are mostly slab-on-grade builds with PEX plumbing and irrigation. Irrigation and fixture leaks are more common there than slab leaks, which is why separating the irrigation line from the house during a meter test matters.
How Leaks in Newer Homes Are Found
Detection works the same way as in older homes: confirm with the meter, isolate hot and cold, trace the lines and pinpoint. PEX carries sound less than copper, so providers often rely more on thermal imaging and tracer gas. See our step-by-step guide to what happens during slab leak detection.
Frequently Asked Questions
Are slab leaks common in new homes?
They are less common than in older homes, but fittings, construction damage and settling can still cause them.
Does PEX prevent slab leaks?
PEX resists corrosion, but fittings can fail and the pipe can be damaged during construction.
Will my builder warranty cover a slab leak?
It depends on your warranty terms. Read the plumbing section and report any leak in writing.
Should I get a leak check before my warranty ends?
It is a smart step. A meter test is free to do yourself, and a provider can test further if it shows a leak.
