Sharon · Leak Detection
A ceiling stain, a meter that won't stop, or a water bill that jumped in Sharon? Call or send a request to reach an independent plumber who traces hidden leaks in Sharon homes.
Sharon, Massachusetts
Every drop in a Sharon home comes from six town wells. The 2025 water report says the town pumped 425 million gallons that year against a state limit of 650 million, and in 2026 a Level 2 drought led the town to limit outdoor watering to handheld hoses from May 1 to October 1. A leak in one house won't move those totals, but you pay for water nobody uses, and in a septic home a running toilet or dripping fixture also feeds extra water to the tank and leaching field.
Hidden leaks reveal themselves slowly: a ceiling stain that spreads, a damp cabinet floor, or a meter still turning with every tap closed. With 38.8% of Sharon's homes built before 1960, by census estimates, original galvanized supply pipe and aging copper joints are common suspects.

If the dial creeps while no water is in use, water is escaping somewhere between the meter and the fixtures.
Compare like seasons; a jump without a new pool, guests, or garden watering is worth investigating.
Stains, soft drywall, or bubbling paint below plumbing fixtures often mark a slow drip above.
Corrosion at joints often comes before a drip, especially in pipe that has been in service for decades.
Hissing or a tank that tops itself up every so often means a flapper or fill valve is letting water through.
Local knowledge
Your service line, the town's water treatment, and its rebates all bear on a leak job.
Service Line Map
Some Sharon service lines installed before 1960 were lead, and the town sent letters by November 15, 2024 to owners whose lines were lead, galvanized, or unknown. Its interactive service line map shows what's on record for your address, which is worth checking before a plumber repairs a leak near the meter.

Corrosion Control
The town treats its water for corrosion control, and 2025 sampling found a 90th-percentile lead level of 0.002 ppb with no samples over the action level. Good system results don't rule out a corroded pipe inside your own house, so pinhole leaks still deserve a look.
Hose Connections
Sharon's water report recommends hose-bib vacuum breakers on inside and outside hose connections. While a plumber is hunting a leak, have them check hose bibs as well, since a cracked frost-proof faucet can leak inside the wall.
Fixture Rebates
The town offers rebates on 1.28 gallon-per-flush toilets and clothes washers to town water users, subject to funds each fiscal year. If tracing turns up an old, running toilet, see whether a rebate is open before you replace it.

Right now
A few quick checks tell you how urgent the problem is.
If water is dripping near a light fixture, outlet, or the panel, stay back and call 911 or Eversource; don't touch wet electrical equipment.
Turn off every fixture and appliance, write down the meter reading, and check it again after an hour or two of no use. Any change means a leak.
If water is visibly running, close the main shutoff and open a basement faucet to relieve pressure in the lines.
Add a few drops of food coloring to each toilet tank. Color showing in the bowl within minutes means a leaking flapper.
What to expect
A plumber usually starts by isolating parts of the system, closing valves to see whether the meter stops, then pressure-testing individual branches. Moisture meters, thermal imaging, and acoustic gear narrow the search so only a small patch of wall or ceiling has to come open.
Once the leak is found, the plumber will look at the pipe around it. In houses from the 1950s, one pinhole in galvanized or thin copper often means others are coming, and repiping a section may beat a patch. Repairs and repiping go through the Building Division, whose plumbing inspector works by appointment on Monday, Wednesday, and Thursday afternoons.
If the leak is on the service line between the meter and the street, ask the plumber to check with the Water Division before digging, particularly if the town's map lists lead, galvanized, or unknown material at your address.
Hire smart
Plumbing and gas fitting in Massachusetts require a license from the Board of State Examiners of Plumbers and Gas Fitters, and most plumbing work needs a permit from the town's plumbing inspector.
Look up the plumber on the state's occupational license search; a pipe repair needs a permit filed by a plumber with a Massachusetts license.
Ask how they'll locate the leak and how much wall or ceiling they expect to open before work starts.
Have the plumber explain whether the surrounding pipe is sound, and get both options in writing.
Find out whether drywall and finish repair are part of the job or left to you.
Costs
Detection time depends on how well hidden the leak is and how many branches the plumbing has. A leak under a slab or in a finished ceiling takes longer to pin down than one in an open basement.
Repair costs follow the pipe material, the access, and whether a patch or a new section is the right fix. Ask for a written estimate covering detection, repair, permit, and wall restoration, and weigh the cost of waiting: a slow leak keeps adding to the water bill and the load on your septic system.

Turn off all water use, read the meter, and check it again an hour or two later. Movement means water is going somewhere. Stains, musty smells, and a higher bill than the same season last year are other clues.
The town posts an interactive service line map showing what it has on record, and owners of lead, galvanized, or unknown lines received letters by November 15, 2024. A plumber can confirm the material where the pipe enters your basement.
Galvanized steel rusts from the inside, and copper can thin at bends and joints after decades of use. When one pinhole appears, ask the plumber to check the condition of the nearby pipe before deciding on a patch.
It can. A toilet or fixture that runs all day sends a steady stream to the tank, which can overload the leaching field over time. Fixing small leaks is part of looking after the system.
Most pipe repairs and all repiping need a plumbing permit from the Building Division, filed by the plumber. Replacing a toilet flapper or faucet washer doesn't, but ask if you're unsure.
