6 Benefits of Water Jetting for Seattle Homeowners

By Bob Oates | June 8, 2026

Hydro jetting, also called high-pressure water jetting, is one of the most effective methods available for cleaning clogged drain and sewer lines. Unlike traditional drain snaking, which often creates a small opening through a blockage, hydro jetting uses a controlled stream of high-pressure water to remove buildup throughout the entire pipe. At Bob Oates, hydro…

Spring Plumbing Checklist: 6 Ways to Get Your Home Ready for Warmer Weather

By Bob Oates | June 1, 2026

Spring is a popular time for home maintenance in the Seattle area. As temperatures rise and homeowners spend more time outdoors, it’s also a good opportunity to check on the plumbing system that worked hard through the winter months. A few simple inspections can help identify small issues before they turn into larger repairs. Whether…

Emergency Plumbing Issues You Can Avoid

By Bob Oates | May 25, 2026

Plumbing emergencies rarely happen at a convenient time. A clogged drain before work, an overflowing toilet during a family gathering, or a leaking pipe overnight can quickly turn into stress, cleanup, and unexpected repair costs. The good news? Not every plumbing emergency appears without warning. Many urgent plumbing problems begin as small habits or maintenance…

6 Things That Should Never Be Flushed

By Bob Oates | May 24, 2026

The toilet and the trash can are not the same thing. Your toilet is designed to handle two things: human waste and toilet paper. But every day, household items that seem harmless get flushed anyway — and many of them can contribute to clogs, sewer backups, damaged pipes, and unnecessary repair costs. Trash can do a lot…

Emergency Plumbing Seattle: Keep Your Home Safe By Calling the Professionals

By Bob Oates | May 22, 2026

A plumbing emergency rarely happens at a convenient time. Whether it’s a burst pipe, overflowing toilet, sewer backup, sudden loss of water, or a leak that won’t stop, knowing when to act can help protect your home and limit damage. This guide covers common signs of a plumbing emergency, how to recognize when professional help…

Pipe Issues Seattle Homeowners Shouldn’t Ignore

By Bob Oates | May 12, 2026

A hidden pipe problem can turn into a major sewer repair before most homeowners even realize something is wrong. Slow drains, recurring backups, foul odors, or unexplained wet spots in the yard are often signs that a sewer line is beginning to fail. And in many Seattle-area homes — especially older properties with clay or…

How Spring Can Lead to Sewer Backups

By Bob Oates | May 5, 2026

Spring in Seattle brings its own set of troubles to the sewer system. In the springtime, sewer backups are most common because of the thawing snow and seasonal rain. The ground is usually too frozen to soak up the water from the rainy season. This results in water leaking into the walls and basements of…

Signs of a Sewer Line Belly (And What To Do)

By Bob Oates | May 1, 2026

Every homeowner’s goal is to maintain a comfortable and safe environment. However, unexpected plumbing issues — and a sewer line belly is pretty high on that list — can quickly disrupt that peace. Conducting proper, regular sewer inspections are key to healthy drainage and sewage systems staying that way. They’re also essential, once a problem…

Importance of Sewer Inspections (And Why They Can Save You Thousands)

By Bob Oates | April 29, 2026

Your sewer line is one of the most important — and most overlooked — systems in your home. Because it’s buried underground, problems often go unnoticed until something goes wrong: slow drains, recurring clogs, or even a full sewer backup. By that point, repairs can be expensive, disruptive, and stressful. That’s why regular sewer inspections…

High Pressure Water Jetting in Seattle: Do You Need It?

By Bob Oates | April 28, 2026

Clogged drain and sewer lines don’t usually happen overnight. Most problems build slowly — grease, sludge, soap residue, and debris accumulate along pipe walls until water can no longer flow freely. When basic drain clearing isn’t enough, high-pressure water jetting (also known as hydro jetting) is one of the most effective ways to fully restore…
