Leak Detection Services in Connecticut

A stain on the ceiling, a meter that spins with every tap off, or a well pump that keeps running means water is going somewhere. We find the leak and quote the fix before we open anything up.

Quick answer: We confirm the leak at the water meter or well pump with every fixture off, then isolate sections of the system to narrow it down. We check toilets, the water heater and exposed pipes, trace moisture around stains, and use a drain camera if a drain line is suspected. The goal is to pinpoint the source before opening any wall or ceiling.

Leak detection is the work of finding where water is escaping from your plumbing when you cannot see it. Hidden leaks show up as ceiling stains, soft floors, musty smells, peeling paint, a water bill that climbs for no reason, or a well pump that cycles when nothing is running. The goal is to find the exact source with as little damage to your walls and floors as possible, then fix it. Fullerton Plumbing provides leak detection for homes and businesses across Connecticut, 24 hours a day, including leaks that need attention right now.

We start with the simplest checks and move to more targeted ones. That means reading the water meter with every fixture off, checking toilets for silent leaks, isolating sections of the system, and inspecting under sinks, behind access panels and around the water heater. Leaks are not always in supply lines. A cracked drain pipe or a failed shower pan can soak a ceiling just as badly, and our drain cameras help us check those. Once we find the source, you get an upfront quote for the repair.

How it works

Our Leak Detection Process

Confirm a Leak

We start at the water meter or well pressure tank with every fixture off. Movement on the meter or a pump that cycles tells us water is escaping. We also check toilets, the water heater and outside spigots, since those common leaks are quick to rule in or out.

Isolate the Area

We shut sections of the system and watch for pressure loss to narrow down where the leak is. We look under sinks, in vanities, at access panels and along exposed basement pipes, and we use moisture readings around stains to trace water to its likely path.

Pinpoint the Source

When the clues point to a wall, ceiling or floor, we narrow the spot before opening anything. If a drain line or shower pan is suspected, we can run a drain camera. The aim is a small, precise opening rather than tearing out a whole room.

Quote and Repair

You get an upfront quote for the repair before we start. We fix the leaking pipe, fitting or drain, test the line under normal pressure and confirm the meter or pump stops moving. We clean up the work area and explain what caused the leak.

Why Connecticut Homes Develop Hidden Leaks

Older Connecticut homes hide plumbing in places that make leaks hard to spot. Colonials, Victorians and three family houses in cities like Hartford, Meriden, New Britain and New Haven often have decades of patched repairs, mixed pipe materials and galvanized lines that corrode from the inside until a pinhole opens behind plaster. Bathrooms stacked above kitchens on each floor of a three decker mean one slow leak can stain two ceilings. Cast iron drains crack along the top with age, and a leaking drain behind a wall can look exactly like a supply leak.

Homes on private wells, common in Litchfield, Tolland and Windham counties and in towns like Wilton and Weston, have no water bill to warn them. Instead, a well pump that turns on in the middle of the night is often the first clue. Winter adds another cause: a pipe that froze and cracked in an exterior wall or crawl space in January may only start leaking when it thaws. We look at the whole picture, house age, water source and season, when we trace a leak.

Pricing

What Affects the Cost of Leak Detection

Leak detection cost depends on how hidden the leak is and how much of the system we need to test. A leak at a toilet or under a sink is quick to confirm. A leak inside a finished wall, ceiling or floor takes more isolation and tracing. Whether the leak is in a supply line or a drain line changes the tools we use, and drain leaks may call for a camera. The repair itself depends on the pipe, location and access. You get an upfront quote before any work starts.

FAQ

Leak Detection Questions, Answered

We confirm the leak at the water meter or well pump with every fixture off, then isolate sections of the system to narrow it down. We check toilets, the water heater and exposed pipes, trace moisture around stains, and use a drain camera if a drain line is suspected. The goal is to pinpoint the source before opening any wall or ceiling.

With no water bill or town meter, watch the well pump and pressure tank. Turn off every faucet, toilet and appliance, then listen for the pump. If it kicks on or the pressure gauge drops while nothing is running, water is leaking somewhere. Toilets are a common cause. If you cannot find it, call us to trace it.

No. It can come from a supply line, but it is just as often a leaking drain, a failed wax ring under a toilet, a cracked shower pan or worn grout and caulk around a tub. We test the supply side and run water through each drain separately to see which one causes the leak, then quote the right repair.

Yes. A slow leak that keeps drywall, insulation or wood framing damp can lead to mold and rot over time, which is why musty smells are worth taking seriously. The first step is stopping the water. We find and fix the leak with an upfront quote, and we let you know when the damaged materials should be dried or replaced.

Yes. If water is actively coming through a ceiling or wall, call us at any hour. Shut off the main water valve first if you can. We dispatch the nearest available technician, stop the water, find the source and repair it, giving you an upfront quote before the repair starts. We clean up the work area afterward.
