Damp cabinet or dripping valve?
A slow drip under the sink can rot a cabinet in months. Call to be connected with a provider.
(813) 303-9621Free call connection · Open 24/7 · Plant City, Brandon, Valrico, Seffner & DoverFixture and valve leak detection checks faucets, shut-off (angle stop) valves, supply hoses, sink drains and garbage disposals for leaks, inside cabinets and behind walls. Providers inspect each connection, run water through each fixture, and use an acoustic probe on valves, which also helps trace hidden leaks further down the line because the leak sounds loudest at the valve closest to it.
Where Do Fixtures Leak?
| Part | Typical leak |
|---|---|
| Angle stop (shut-off valve) | Weeps at the stem or packing nut, or won't fully close |
| Supply hose | Drips at the crimped end, bulges or bursts with age |
| Faucet base and cartridge | Water under the faucet deck or inside the cabinet when running |
| Sink drain and P-trap | Loose slip nuts, worn washers, cracked trap |
| Garbage disposal | Leaks at the sink flange, dishwasher inlet or body |
| Dishwasher connection | Supply or drain hose under the sink |
| Hose bibs outdoors | Drips, or leaks inside the wall behind the bib |
Signs of a Fixture or Valve Leak
- Swollen, stained or soft cabinet bottoms
- A musty smell when you open the sink cabinet
- White mineral crust on valves and fittings
- Water on the counter around the faucet base
- A valve that drips when you touch it, or won't shut off completely
- Damp drywall behind the vanity or kitchen sink
- Bugs gathering under the sink
How Valve Listening Finds Hidden Leaks
Valves are more than leak points. They're listening posts. Every angle stop, tub valve and hose bib is connected to the same pressurized system, so a technician can press an acoustic probe against each one and compare the sound. A leak somewhere under the slab or inside a wall sounds louder at the nearest valves and fades farther away. That pattern narrows the search before any ground microphones come out.
This is a standard first step in slab leak detection and hidden leak detection. During a fixture check, it also confirms whether the drip you see is the whole story.
Why Fixtures Wear Out Faster in Plant City
Groundwater from the Floridan aquifer is mineral-rich. Scale builds up on cartridges, valve stems and washers, which wears seals and makes valves stick. The same minerals are hard on water heaters. Angle stops that haven't been turned in years often seize or leak the first time someone tries to close them. Humidity under sinks also corrodes fittings faster.
Pro tip: Gently turn each shut-off valve under your sinks and toilets once or twice a year. If one is stuck or starts dripping, it's better to know before an emergency.
What You Can Check
- Empty the cabinet and put a dry paper towel on the floor of it. Check it after a day.
- Run each faucet with a dry hand under the connections to feel for drips.
- Look at supply hose ends for rust, bulges or crust.
- Fill the sink, then release it and watch the drain connections.
- Do a meter test to see if a hidden leak is running elsewhere.
Repair Options
Most fixture leaks are quick repairs: tightening or replacing slip nuts, swapping a supply hose, replacing an angle stop or a cartridge. If the cabinet or wall behind it is wet, drying matters too. Call (813) 303-9621 for a free quote through our Plant City leak detection line.
Warning: If a supply hose is bulging, close the valve and replace it right away. Bulging hoses can burst without warning and flood a room.
Fixture, Valve & Under-Sink Leak Detection FAQs
Is a small drip under the sink worth fixing?
Yes. Slow drips soak cabinet floors, walls and subfloors over time and can lead to rot and mold, especially in Florida humidity.
Why won't my shut-off valve close all the way?
Mineral scale and age stiffen valve stems and wear the seals. Valves that haven't been turned in years often won't seal or start dripping.
How often should supply hoses be replaced?
They wear with age. Replace any hose that shows rust, cracks, bulges or crust at the ends.
Can a fixture leak cause a high water bill?
A dripping faucet adds up over time, but a large bill jump usually points to a running toilet, irrigation or a hidden supply leak.
