Frequently Asked Questions

Answers to the most frequently asked plumbing questions from Lake St. Louis homeowners.

What is trenchless sewer repair and is it right for my Lake St. Louis home?

Trenchless sewer repair in Lake St. Louis 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.

When should I replace my water heater in Lake St. Louis, MO?

Most tank water heaters last 8 to 12 years. Consider replacement when your unit is over 10 years old, produces rusty or discolored water, makes rumbling or popping noises, or requires frequent repairs. Magnet Plumbing offers free water heater assessments to help Lake St. Louis homeowners decide between repair and replacement.

How do I prevent frozen pipes in Lake St. Louis, MO?

To prevent frozen pipes in Lake St. Louis, 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.

How long does a plumbing repair take in Lake St. Louis, MO?

Simple repairs like faucet replacement, toilet repair, or drain clearing in Lake St. Louis often take 1 to 2 hours. More complex jobs like slab leak repair, water line replacement, or water heater installation typically take a half to a full day. Whole-home repiping can take 2 to 4 days. Magnet Plumbing provides a clear time estimate before starting any job.

How do I find a licensed plumber in Lake St. Louis, MO?

When hiring a plumber in Lake St. Louis, always verify their MO license and insurance. A licensed plumber must pass state examinations and carry liability coverage that protects your property. Magnet Plumbing employs licensed, background-checked plumbers throughout Missouri — call (844) 618-0753 to schedule service or get a free estimate.

How can I tell if I have a slab leak in my Lake St. Louis home?

Signs of a slab leak in Lake St. Louis 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.
