Drain Inspections and Sewer Detection

If your home is being plagued by pungent odors or wastewater backing up from the sinks or drains, don’t hesitate to call our reliable, punctual staff at Bob Oates for assistance. Our drain inspection services in Seattle, WA, and surrounding areas are designed to accurately pinpoint problems as well as guarantee an ideal solution for the issue after it’s correctly identified.

Prior to any attempts to repair or clean the pipe, we first take the time to perform a thorough and precise drain inspection allowing us to solve blocked drain symptoms promptly and professionally. Our plumbing company has many solutions for fixing blocked drains that are personalized for each situation we encounter. Our expert techs will consult with you and discuss with you the most cost-effective approach to solving your slow or blocked drain.

Kitchen and bathroom sinks have a P-trap in the pipeline, a u-shaped bend under the basin drain, and can usually be found inside of the basin cabinetry. If we find that the clog is trapped in this location, we will replace and seal the P-trap properly so that no leaks form after our examination.

For blockages or breaks existing further along the length of the pipeline, we perform a sewer camera inspection to determine the location and cause of the symptoms you are experiencing. We utilize our waterproof drain inspection camera attached to the end of a fiber optic cable that is spooled into the pipe from the open P-trap or from the sewer pipeline access point outside the building.

Once a clog or corrosion is discovered in the pipe, we will clean and repair the pipe as needed. One of our most innovative cleaning processes, hydro jetting, relies on high-pressure blasts of water from a hose and a water jetting head to remove the presence of blockages and other problems.

The forceful water jets clean the inside surface of the drainpipe, removing corrosion and dissipating clogs. Once the high-pressure water jetting is completed, the drain inspection camera is redeployed to confirm that the pipe is clean and to check for uncovered cracks.

If cracks are discovered, our experienced techs are prepared to use a cured-in-place pipe (CIPP) liner process. This process inserts an epoxy resin coated liner inside your current pipe. The camera equipment is again deployed to validate that the liner is situated accurately.

Once the proper location is confirmed, the liner is inflated, molding the resin against the interior surface of the pipeline. The liner remains inflated within the pipe for a few hours, allowing the resin to cure and harden into a new smooth and unbroken interior surface of the pipe.
