The signs of a hidden plumbing leak usually include a water bill that rises for no clear reason, a leak indicator on the meter that spins with every tap closed, a damp or earthy odor, floors that feel soft, paint that peels or bubbles, and trim that swells. You might never see a drop of water, but the house often shows these changes first.
Clues From the Meter and Bill
Look at your water usage for the same months last year. A noticeable increase without new appliances or extra people at home is worth investigating. Then turn off every faucet and appliance and watch the small leak dial on the meter. If it moves, water is going somewhere.
Clues in the Walls and Floors
- Paint that blisters near the floor or ceiling
- Baseboards that swell or pull away
- Floor tiles that loosen or sound hollow
- Cabinet floors under sinks that feel spongy
- Small dark spots of mold along the bottom of a wall
Pay attention to walls next to bathrooms, the kitchen, and the laundry area.
Clues You Can Smell and Hear
A musty odor that is strongest in one spot often means moisture behind a wall or under a floor. At night, a faint hiss or drip near plumbing walls can point to a pressurized supply line.
Toilets First
Before assuming the worst, test each toilet. A few drops of food coloring in the tank, with no flushing for 15 minutes, will reveal a leaking flapper. It is the most common silent leak and an easy fix.
If the signs point to a leak you cannot find, a leak survey can identify the location without tearing into walls blindly. Regular checks under sinks and around fixtures are part of looking after the plumbing in your home all year long. Call JPR Plumbing at (833) 603-1840.
