FAQs

Common Questions About Leak Detection & Repair

What are the signs of a hidden water leak?

Watch for a water bill that rises without explanation, the sound of running water when every fixture is off, musty odors, warped flooring, peeling paint, or stains on ceilings and walls. Mold in a cabinet or corner is another warning sign. If you notice any of these, it is worth having the source located before the damage spreads further.

How can I check my water meter for a leak?

Turn off every faucet, appliance, and fixture in the house, then look at your water meter. Many meters have a small leak indicator dial that spins when water is moving. You can also write down the reading, wait an hour or two without using water, and check again. If the numbers changed, water is escaping somewhere and should be tracked down.

What causes pipes to start leaking?

Common causes include corrosion in aging pipes, water pressure that runs too high, loose or worn fittings, and shifting soil around buried lines. Freezing temperatures during St. Louis winters can also crack pipes in exterior walls, crawl spaces, and unheated basements. Once we find the leak, we look at what caused it so the repair addresses the real problem and not just the symptom.

What should I do first if I find an active leak?

Shut off the water. Most homes have a main shutoff valve in the basement near where the water line enters, often close to the meter, and many fixtures have their own shutoff valve underneath. Move valuables away from the wet area, soak up standing water, and keep clear of any outlets or wiring near the water. Then book a repair through the Schedule Now button.

Is a small drip under the sink worth fixing right away?

Yes. A slow drip under a sink can soak the cabinet base for weeks before you notice warping, swelling, or a musty smell. That constant moisture invites mold and can damage the floor underneath. Small leaks are also usually the easiest and least disruptive to repair when they are caught early, so it pays to have Plumbing Masters take a look sooner rather than later.

 Trustindex verifies that the original source of the review is Google. Needed to have the kitchen drain line cleared for the first time after 30 years in the house.  Was able to schedule service promptly, which was handled professionally and competently.  I think the price for the drain cleaning was reasonable, though it is a bit higher than what is seen sometimes in online advertising from other companies.  Have been using plumbing master’s for many years and things are always handled competently by respectful and knowledgeable professionals.
