Frequently Asked Questions

Common questions about plumbing services in South Lake Union, WA.

How do I shut off my water in a plumbing emergency in South Lake Union?

Your main water shutoff valve in South Lake Union 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.

How often should I have my drains cleaned in South Lake Union?

Most South Lake Union 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 South Lake Union. Magnet Plumbing uses hydro-jetting and snaking to thoroughly clear all drain types.

What plumbing emergencies require immediate service in South Lake Union?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in South Lake Union. A burst pipe can release hundreds of gallons per hour, and gas leaks pose fire and explosion risks. Magnet Plumbing provides 24/7 emergency plumbing service throughout South Lake Union and surrounding Washington communities.

Is it safe to use chemical drain cleaners in my South Lake Union home?

Chemical drain cleaners can damage older pipes in South Lake Union homes, especially PVC, brass, or aging galvanized plumbing. The caustic chemicals can eat through pipe walls over time and are hazardous if they splash on skin or eyes. A professional drain cleaning by Magnet Plumbing is safer, more effective, and prevents pipe damage — costing less in the long run.

What is trenchless sewer repair and is it right for my South Lake Union home?

Trenchless sewer repair in South Lake Union 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 South Lake Union, WA?

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 South Lake Union homeowners decide between repair and replacement.
