What's actually causing this
Pipes leak at joints when thread sealant dries out, at elbows where water pressure concentrates, or anywhere corrosion has weakened the pipe wall. PVC joints also crack from freezing temperatures or physical impact.

Step-by-step fix
-
1
Shut off the water supply
Turn off the main water shutoff valve. Open a faucet downstream to drain remaining pressure from the pipe.
-
2
Dry the pipe completely
Use a towel and fan to dry the area around the leak. No repair compound bonds to a wet surface.
-
3
Apply a pipe repair clamp (temporary)
Center the rubber gasket over the leak and tighten the clamp screws evenly. This buys time for a permanent repair.
-
4
Cut out and replace the damaged section (permanent)
Cut 2 inches on either side of the damaged area using a pipe cutter. Install push-to-connect (SharkBite) couplings on each side for a no-solder permanent fix.
-
5
Test under pressure
Slowly turn the water back on. Watch the repair area for 10 minutes. Check all connections for moisture.
In Miami, tap water is very hard (250–320 ppm). Miami's water is hard, sourced from limestone aquifers. Mineral deposits are severe. Salt intrusion from the ocean is a growing concern in coastal areas. Corrosion is accelerated by humidity and salt air. Water softeners or filters are very common.
Plumbers in Miami typically charge $110–180/hr. Most homeowners budget $800–2,500 for common repairs like fixture replacement, drain clearing, or valve repairs.
Florida has strict licensing (myfloridalicense.com). Plumbing requires state-licensed plumber. Homeowner exemptions are very limited — only repairs on own home with own labor.
Majority post-1980s construction elevated for flood risk. Copper is standard. Hard water and salt corrosion accelerate fixture failure. Slab-on-grade with salt intrusion risk. Storm surge can flood plumbing systems. Backflow prevention devices are common.
DIY in Miami: Miami's strict Florida licensing requirements, hurricane codes, and environmental hazards make DIY repairs very restricted. Homeowners should hire licensed professionals for plumbing, electrical, and HVAC. Coastal properties require special knowledge and materials.
- The leak is inside a wall or ceiling — accessing it requires opening drywall.
- The pipe is corroded or crumbling — a section repair won't solve systemic corrosion.
- You can hear running water but can't locate the source.
- The pipe is part of a gas line — never attempt gas line repairs yourself.
