Warning signs of a leak
- A water bill that jumps with no change in habits, or a meter that moves with everything off
- On a well: the pump kicks on with no water in use, or the pressure gauge creeps down overnight
- Stains, bubbling paint or soft drywall on walls and ceilings
- Warm spots on tile or concrete floors
- Musty smells, or mold behind cabinets and around the water heater
- The sound of running water when the house is quiet
How plumbers find leaks
A plumber will usually start by isolating sections of the system: shutting valves to see whether the loss is in the hot side, the cold side, an irrigation line or a toilet. From there, tools may include acoustic listening equipment, thermal imaging to trace warm lines in floors and walls, moisture meters, and pressure testing. The goal is to open only the spot that's leaking.
Common leak sources in Pahrump homes
- Toilets: a worn flapper that silently runs into the bowl is one of the most common sources of wasted water.
- Supply lines and shutoff valves under sinks and behind toilets, especially older ones with hard-water build-up.
- Water heater connections and relief valves.
- Outdoor lines: hose bibs, yard hydrants and irrigation lines that split in a freeze or get damaged by digging.
- Older pipe materials: polybutylene and galvanized steel are prone to failure as they age. See repiping.
Repair options
Depending on the location and pipe material, a fix might be a single fitting, a section of new pipe, rerouting a line above the slab, or replacing an entire run. When leaks keep appearing in different places, it may be time to talk about repiping instead of repeated patches. Ask the plumber to show you what they found and why they recommend the fix.
Leak repair FAQ
How do I know if I have a hidden leak?
Turn off every faucet and water-using appliance, then watch your water meter (on utility water) for movement. On a private well, listen for the pump starting or the pressure gauge dropping when nothing is running. Either one suggests water is going somewhere.
What is a slab leak?
A leak in a water line that runs under or through the concrete foundation. Signs include a warm spot on the floor (hot line), the sound of running water when everything is off, damp carpet or flooring, cracks, or unexplained water use. Repair can mean opening the slab at the leak, or rerouting the line through walls or the attic.
Will my homeowner's insurance cover it?
That depends on your policy and what caused the leak. Policies often treat sudden water damage differently from long-term seepage, and some don't cover the pipe repair itself. Take photos and call your insurer. A plumber's written findings can help.
Can I just wrap a leaking pipe with tape?
Repair tape or a clamp can buy time until a plumber arrives, but it isn't a permanent fix, especially on pressurized lines. Shut off water to that line, or the whole house, if you can.
