Know the signs

Signs of a hidden leak.

Most leaks show up somewhere other than where they start.

A higher water bill

Or a well pump that runs when nothing is on.

Stains on a ceiling

Brown rings under a bathroom are a classic drain or supply leak.

Musty smells

Mold and mildew grow where water has been sitting.

The sound of running water

Hissing in a wall when every fixture is off.

How it works

Confirm. Locate. Repair.

You pay to find the leak once, and you get the repair price before we fix it.

  1. 01

    Confirm

    Testing proves there is a leak and which system it is in.

  2. 02

    Locate

    We narrow it down to the fixture, the wall or the line.

  3. 03

    Repair

    You get a price for the fix before any work starts.

Questions

Leak detection, answered.

Answers from licensed plumbers and septic installers. Still unsure? Call East CT at (860) 292-0484.

How much does leak detection cost?
A toilet leak inspection starts from $267, a drain leak diagnosis starts from $515 and a water leak diagnosis without opening walls starts from $718 at Drainworks.
Can you find a leak without cutting into walls?
Usually. We test first and only open a wall or ceiling when the leak is inside it, and then only as much as needed.
How do I stop the next leak?
An automatic shut-off valve or a whole-home leak detection system shuts the water off when it senses a leak.
