Answers to the most frequently asked plumbing questions from Mercer Island homeowners.
Your main water shutoff valve in Mercer Island is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it. If you cannot find your shutoff or it is stuck, call Magnet Plumbing immediately — our emergency crew can help locate and operate the valve to stop water damage.
Trenchless sewer repair in Mercer Island replaces damaged sewer lines using pipe lining or pipe bursting methods — without digging up your yard, driveway, or landscaping. It works for most sewer line problems including cracks, root intrusion, and offset joints. Magnet Plumbing uses camera inspection to confirm trenchless repair is the right approach for your specific line condition.
Plumber rates in Mercer Island typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Magnet Plumbing provides free estimates so you know the full cost before any work begins.
Signs of a slab leak in Mercer Island homes include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, cracks in the foundation or walls, and low water pressure. If you notice these symptoms, call a plumber for professional slab leak detection before the damage worsens.
To prevent frozen pipes in Mercer Island, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Magnet Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.
