Drain Addict — “Blocked Drain 936” — Clearing roots from a toilet branch line
Oliver (Drain Addict @ YouTube; Drain Go) has been called in by Isaac, a plumber, to help with a wastewater drain system where flushing an upstairs toilet causes a downstairs toilet to make a gurgling sound. There is what appears to be a vertical stack pipe along the outside wall of the building, and the drain line is thought to run below a concrete walkway next to the building.
From an inspection opening outside, Oliver starts by sending the drain camera down the line toward the toilets. Some small roots are seen along the way, with a more significant blockage being found some distance down the pipe. The pipe locator is used to find where the blockage is located, and markings are left on the concrete above the pipe using pink spray paint. Given the location relative to the building and the external vertical pipe, Oliver thinks there might be roots within the branch line leading to the toilet.
He moves the camera and jetting reel inside the bathroom. During a previous drain cleaning performed by somebody else, a large hole had apparently been smashed through the ceramic drain portion of the cemented-in toilet, and then covered up using duct tape. Oliver reuses this existing opening, and sends the camera down the toilet’s branch line. Some more roots are soon discovered in the pipe, and the pipe locator is used outside the building once again to find and mark where the obstruction is. The location suggests that the vertical pipe on the outside of the building may be a vent pipe, rather than the stack that the toilets are directly connected to.
They decide to jet the line from the outside inspection opening, and Oliver quickly clears away the roots. It appears as though they may be entering through an old inspection opening at the top of the pipe that is now inaccessible below the concrete walkway. While removing the jetting hose, he clears away some more roots that are observed coming in around another old inspection opening near a different branch line junction.
Isaac has to leave, but before he goes, he helps perform a toilet paper flush test. He flushes some toilet paper down the line, while Oliver watches at the inspection opening outside the building. While some water is observed flowing past the inspection opening, the toilet paper isn’t seen. Isaac performs another flush with more toilet paper, and the paper is clearly seen flowing by on this second attempt.
A small piece of cut-away root at the bottom of the inspection opening shaft is removed using a pincher on a long pole, and Isaac gives Oliver some duct tape he can use to patch up the hole in the toilet’s drain. A final visual inspection of the line is performed by feeding the drain camera through the hole in the toilet, confirming that the pipe is now clear.
Oliver clears away some of the existing tattered duct tape covering the hole in the toilet, and then patches it using the roll of duct tape that Isaac had given him. Another test of the toilet shows that it’s flushing fine, and then the inspection opening cover outside the building is screwed back in place.
