"We found ourselves in a quandary with our plumbing in our 100 yr old house. The first company I called sent up many red flags. I called my daughter's friend who recommended Bob Oates. They came the next day and fixed the problems right away. The employees were professional, capable, respectful, and fun too!"

Sewer Inspection & Repair

FAQs About Plumbing
When should plumbing fixtures be replaced instead of repaired?
At Bob Oates, we always look for cost-effective repair options first. However, replacement is usually the better choice when fixtures are outdated, inefficient, or showing signs of repeated failure. Upgrading to new models can also improve water efficiency and help prevent future leaks.
How can homeowners prevent major plumbing problems?
Scheduling routine maintenance and inspections is the best way to stay ahead of plumbing issues. Our team can check for early warning signs — from slow drains to small leaks — before they turn into expensive repairs. Preventive service is faster, cleaner, and ultimately more affordable.
What are common signs that something’s wrong with your plumbing?
Low water pressure, gurgling drains, sewer odors, or slow-flowing faucets often signal hidden leaks, blockages, or venting issues. If you notice any of these symptoms, it’s time to call a licensed plumber for a professional inspection.
What should I do if I have a plumbing emergency?
First, shut off your main water valve to stop the flow of water. Then, call Bob Oates Plumbing, Sewer & Rooter right away. We’re available 24/7 and can usually be on-site within the hour for urgent plumbing or leak emergencies anywhere in Seattle.
