Hearing Running Water With Taps Off in Brentwood

A quiet house should be quiet. When you hear water moving with every tap off, a supply line is leaking somewhere, and the sound is often the first sign, before any water shows. Homeowners in Brentwood describe it the same way in posts and calls: a faint rush behind a wall, a hiss in a quiet room, or the sound of a tap running when no tap is on. The cause is usually a supply line, not a drain. Drains only make noise when water runs through them. A supply line is pressurised all the time, so a leak in one sounds like water running even when the house is still. The most common spots are a pinhole in a copper line behind a wall, a joint under a slab, or a line in a crawlspace. A warm spot on the floor points to a hot-water line under the slab. A damp patch on a wall points to a line inside that wall. The first check is the meter. Turn off every tap and appliance, then watch the leak indicator. If it moves, the sound is a leak, not the house settling. Do not open walls at random. Acoustic listening and thermal imaging narrow the leak to a small area, so we open only the spot we need. Brentwood clay soil and older copper lines make these leaks common here, and hard water speeds the wear. If you hear running water, note when you hear it, check the meter, and call us. The sooner a supply leak is found, the smaller the repair, and the less water soaks into framing, drywall, and flooring.

Frequently Asked Questions

Is the sound always a leak?

Not always, but a meter that moves with taps off confirms it. A refrigerator ice maker or a water softener can also make water sounds, so we check those first.

Where is the leak most likely?

A pinhole in a copper line behind a wall, a joint under the slab, or a line in a crawlspace are the usual spots in Brentwood homes.

Can you find it without tearing out a wall?

Usually, yes. Acoustic and thermal tools narrow most leaks to a small area, and we open only the spot we need.

How urgent is this?

Urgent. A supply leak runs all the time, so it soaks framing and drywall for as long as it runs. Call the same day you hear it.
