Common Plumbing Problems We Solve

Our team handles everything from small repairs to complex plumbing overhauls. Call us if you’re dealing with:

• Leaking pipes or dripping faucets
• Low water pressure or no hot water
• Slow drains, sewer backups, or toilet overflows
• Broken water lines or visible corrosion
• Tree root invasion that infiltrates and damages pipes
• New fixture installations or remodels

For many Seattle homeowners, these issues start small — but can quickly escalate into costly water damage or mold growth if left unchecked.

We’ll diagnose the problem fast using professional tools and provide a clear repair plan before any work begins.

Prevent DIY Disasters

Trying to fix plumbing issues on your own often leads to more damage, higher costs, and unsafe conditions. Modern plumbing requires specialized tools, materials, and training — all of which our team brings to every service call.

From soldering copper joints to replacing pressurized fittings, our licensed plumbers ensure every connection is leak-free and code-compliant. Save yourself the frustration and risk — let our experts handle it the right way, the first time!

Beyond Plumbing: Complete Drain, Sewer & Water Line Solutions

Because Bob Oates Plumbing, Sewer & Rooter is a full-service plumbing and registered side-sewer contractor, our team handles every part of your home’s underground system — from drains and sewers to water mains — all in-house, with no subcontractors needed.

Drain Cleaning

High-pressure water jetting and professional rooter services quickly clear clogs and buildup without harming your pipes. Our drain cleaning services restore proper flow safely and effectively — perfect for recurring slow drains or stubborn blockages.

Sewer Inspection & Repair

Our licensed technicians perform detailed sewer camera inspections to identify cracks, blockages, or root intrusion before recommending the right fix. Whether it’s a simple spot repair, a section replacement, or a full excavation, we deliver complete sewer repair solutions that restore your system from the ground up.

Trenchless Sewer Repair

For pipes that can be restored without digging, we offer CIPP (cured-in-place pipe) lining and pipe bursting technologies. These modern trenchless repair methods rebuild or replace damaged sewer lines with minimal disruption to landscaping or hardscaping.

Water Main Repair

Hidden leaks or breaks in your water main line can cause low pressure, water damage, or unexpectedly high utility bills. Our crew locates and repairs these issues quickly, using advanced leak detection and minimally invasive replacement techniques to restore reliable water service.
