Signs of a Hidden Water Leak in Your Portland Home

A leak inside a wall or under a slab doesn't always announce itself. These are the signs worth paying attention to.

An unexplained jump in your water bill

If your water bill climbs noticeably without a change in usage, a hidden leak is one of the most common explanations. Comparing a few months of bills side by side can help you spot a trend rather than a one-time fluctuation.

The water meter keeps moving with everything off

Turn off every fixture and appliance that uses water, then check your water meter. If it's still moving, water is flowing somewhere in the system even though nothing should be using it — a strong sign of a leak.

Damp spots, warped flooring, or musty smells

A damp patch on flooring or drywall, warping in wood or laminate flooring, or a persistent musty smell with no obvious source can all point to moisture from a slow leak building up behind a wall or under a slab.

Low water pressure in specific fixtures

If pressure has dropped at one or two fixtures specifically, rather than the whole house, water may be escaping through a leak in the line feeding that area before it reaches the fixture.

The sound of running water with nothing on

Hearing water running when every fixture is off is a fairly direct sign — it's worth locating where the sound is coming from, since it can help narrow down which section of the plumbing to check first.
