Common questions about plumbing services in St. Peters, 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 St. Peters homeowners decide between repair and replacement.
Most St. Peters homeowners benefit from professional drain cleaning every 1 to 2 years as preventive maintenance. Homes with large families, frequent cooking, or older plumbing may need service more often. Tree roots, grease buildup, and hair are the most common causes of drain problems in St. Peters. Magnet Plumbing uses hydro-jetting and snaking to thoroughly clear all drain types.
To prevent frozen pipes in St. Peters, 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.
Your main water shutoff valve in St. Peters 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.
Signs of a slab leak in St. Peters 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.
Simple repairs like faucet replacement, toilet repair, or drain clearing in St. Peters 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.
