Manhasset, NY
When the water bill climbs and nothing in the house looks wrong, a leak is often hiding inside a wall, under a floor, or along a buried line. JPR Plumbing helps Manhasset homeowners trace hidden leaks to their source so that only the area that needs repair is opened.
The first step is proving that water is actually escaping. With every fixture and appliance off, a moving water meter means water is escaping somewhere between the meter and the taps. From there, the search narrows to indoor lines, outdoor lines, and specific fixtures.
It helps to know whether the leak is on the supply side or the drain side. Supply leaks usually run all the time, while drain leaks show up only when water is used. A plumber uses those clues, along with where moisture appears, to work back toward the pipe that is actually leaking.
Finding the leak first protects the house. Opening walls or ceilings at random adds repair work, while a careful search keeps the opening small and puts it right where the repair needs to happen.
While you wait: if the meter moves with everything turned off, close the main shut-off to limit damage. Keep clear of light fixtures and outlets near damp ceilings or walls, and avoid cutting into walls where wiring may run. If a ceiling is sagging with water, keep everyone out of the room below.
Higher use without a change in habits often points to water escaping somewhere.
Discoloration or soft spots on walls and ceilings usually sit near a leaking pipe.
Movement with all water off confirms a leak in the system.
Older supply pipe can develop small leaks at fittings and bends.
Lines to outdoor faucets or irrigation can leak into the soil unseen.
Drain pipes can leak only during use, which makes them harder to find.

Indoor and outdoor lines, and individual fixtures, are checked one at a time.
The location is narrowed down before any finish is opened.
Manhasset homes
Homes with outdoor faucets, garden lines, and several bathrooms have more places for water to hide. The search usually starts by separating indoor plumbing from outdoor lines. Inside, upstairs bathrooms and kitchens are the usual suspects, because water from those rooms can travel along joists and framing before it shows up as a stain somewhere below.
01
The EPA’s guide to mold and moisture says mold usually will not grow if wet materials are dried within 24 to 48 hours. A hidden leak keeps materials wet far longer than that.
02
Close the valve feeding outdoor faucets and irrigation, then check the meter again. If it stops, the leak is outside.
03
Moisture that appears only after showers or laundry points to a drain or fixture connection. A supply leak, by contrast, usually keeps leaking whether or not any water is in use.
Read the meter at night after the last water use and again first thing in the morning. A change with no water used is a strong sign of a leak. Write both readings down so you can share them when you call.
Once the source is pinpointed, repairing the failed pipe or fitting is the next step, often on the same visit. For other plumbing concerns, see the types of repairs we handle for Manhasset homes.

When to call
The work depends on how many lines could be involved, how the area is finished, and whether the leak is indoors, outdoors, on the supply side, or on the drain side. Leaks in unfinished basements are usually quicker to trace than those behind finished walls or under floors. The findings are explained to you before a repair is scheduled. Where damp has lingered, drying out the space and looking for mold may come next.
Questions
Shut off every tap and the sprinklers, then keep an eye on the meter. If it moves, water is escaping somewhere.
Yes. A leak on an outdoor faucet line or irrigation pipe can run unnoticed for a long time.
Only once the location is narrowed down, and only as much as the repair requires.
Not always. Groundwater and condensation can cause dampness too. A meter check helps tell the difference.
Water can travel along pipes, joists, and framing before it soaks through, so a stain may appear some distance from the actual leak.
If you like to understand the problem first, start with our notes on bubbling paint in the bathroom. Our guide to telling a roof leak from a pipe leak may help too.
Call (833) 603-1840 weekdays between 9:00 a.m. and 9:00 p.m., or send a request online. Tell us where you have seen moisture and whether the meter keeps moving.
