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 Phoenix, tap water is very hard (320–450 ppm). Phoenix has some of the hardest water in the U.S., sourced from Colorado River and groundwater. Mineral deposits are severe and visible within weeks on fixtures. Water heaters fail quickly (6–8 years). Water softeners are nearly universal among informed homeowners.
Plumbers in Phoenix typically charge $90–150/hr. Most homeowners budget $800–2,500 for common repairs like fixture replacement, drain clearing, or valve repairs.
Arizona has minimal licensing for plumbers. Cities (Phoenix) require permits. Homeowners can perform plumbing with permits.
Majority post-1990s construction. Copper is standard. PEX is increasingly used. Hard water means sediment buildup in water heaters is severe; flushing annually is essential. Slab-on-grade is common; underground pipe leaks are expensive repairs.
DIY in Phoenix: Phoenix is very DIY-friendly. Arizona's permissive licensing and culture support homeowner work. Hard water management and HVAC maintenance are common DIY focuses. Cooling system care is critical and often DIY-maintained.
- 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.
