Oliver (Drain Addict @ YouTube; Drain Go) has been called in by Isaac, a plumber, to work on a bathroom sewage system that isn’t draining.
Isaac cuts out part of the vent pipe along the outside wall of the building to create an opening for accessing the sewage system, rather than having to use a nearby gully that is full of sewage.
Using this new access point, Oliver begins to jet the line. He eventually breaks through the blockage, and the backed-up sewage drains away. The drain camera is used to try to discover what the problem might have been, but there’s still some residual murky water remaining in the pipe. Isaac goes inside the bathroom and runs some cold water to try to make it easier to see using the drain camera. With the remaining sewage displaced by clear water, an inspection is performed using the drain camera. Evidence of roots is observed.
Oliver decides to jet up toward the toilet, to ensure that part of the system is clear. Isaac flushes some toilet paper down the toilet to help them determine how the toilet connects to the system. Even after a few flushes, dirty water is still coming past the camera. Oliver uses the camera to check up the line connecting to the bath tub and floor drain, and it seems clear, except for some roots that he is able to remove by hand. After some more water runs through the toilet connection, it eventually comes through clear.
The reverse nozzle is used to try to direct the jetting hose back up the pipe leading to the toilet, but the first attempt isn’t successful. The jetter accidentally causes Isaac, who’s in the bathroom near the toilet, to get splashed with some water. Another attempt at sending the hose back up toward the pipe leading to the toilet is successful, and Oliver jets away any roots that might be there.
Some further inspection of the system is performed using the drain camera, and more roots are discovered farther along. Oliver jets the line some more, and then the camera is used again to determine that it might be near an inspection opening. Roots and disjointed pipes are also noticed. The pipe locator is used to find this location, and it does appear to be at the inspection opening. The lid is removed, and the camera is observed in the pipe.
Oliver moves the jetting reel and the camera to this inspection opening, and performs some more jetting to clear up the roots that were observed earlier. He then moves the jetting reel to the boundary trap shaft’s inspection opening. While he jets from there to the earlier inspection opening, Isaac pulls the drain camera backward, capturing footage of how the reverse nozzle works to cut away roots. Eventually the nozzle reaches the inspection opening’s connection.
With the line now clear, Isaac performs a toilet paper flush test, but Oliver doesn’t notice the paper come through at the boundary trap. Just to be sure the system is clear, he ends up using a bucket to send more water and toilet paper through the system, while Isaac films at the boundary trap’s inspection opening. This test is successful.
Oliver replaces the gully’s lid, and then shows how Isaac has repaired the vent pipe that had been cut earlier, with the repaired segment now including an inspection opening in case access is needed in the future.
