Oliver (Drain Addict @ YouTube; Drain Go) has been called in by Isaac, a plumber, to clear a blocked drain for a newly-renovated bathroom. Isaac had already cut the stack pipe in a crawlspace area, and pulled out what appears to be fragments of tile or other demolition debris from the old bathroom. The drain camera reveals that there is additional debris in the line.
Some more of the easy-to-reach fragments are pulled out by hand by Oliver, including what appears to be an old drain grate of some sort. Once he removes all of the debris that he can reach, he decides to use the high-pressure water jetter to pull back the remaining debris where possible, with the rest of it being pushed toward the boundary trap. A plunging rod with a disc on the end has been inserted down the boundary shaft to try to catch any material before it ends up in the trap.
Oliver starts jetting the line and removes some more of the looser debris, but a subsequent camera investigation shows a significant blockage. He changes to a smaller jetting nozzle, which does get more of the rocky fragments out, including a small unknown mushroom-like object. After using the camera again, Oliver switches to a reverse nozzle, to try to blast the larger pieces out. The camera reveals that some of the chunks were removed, but some still remain. The nozzle is changed once more, and some more jetting is done, with an old tampon eventually being brought back on the end of the hose.
Instead of jetting some more, Oliver decides to try sucking out the debris using a wet/dry vacuum. He puts the vacuum hose down the pipe, and although some pieces are removed by the vacuum, the work is still going very slowly.
He begins to remove some slabs on the floor surrounding the pipe, and then begins digging down into the ground using his hands. Since the soil appears to be quite soft and sandy, it’s easy for him to quickly clear away a lot of it, revealing more of the drainage pipe. A handheld reciprocating saw is used to cut through some of the drain pipe, and this allows for several fittings and some pipe to be removed.
With the blockage now more easily accessible, Oliver is able to remove some more chunks by hand. Some of the chunks are quite large and firmly wedged into the pipe. He begins to pull out more of the debris, and piles it on top of one of the floor slabs he’d moved earlier. Although he manages to get most of the pieces, the camera shows that there is some remaining debris just beyond his reach. The jetter is used again to clear away some of this debris, although further camera inspection still reveals more pieces. Some more jetting is done to try to clear them away.
Oliver runs some water through the system to try to flush out any remaining debris, but when he checks the plunger that was inserted into the boundary shaft earlier, it doesn’t seem to have caught anything.
The larger drain camera is then inserted into the drain. Some sand and debris are still observed in the line, so some more jetting is done to try to push them to the boundary trap. After reaching the boundary trap with the nozzle, more water is run down the drain pipe. Some additional camera work shows that the pipe is clear, but the rod blocking the boundary shaft didn’t catch it. To ensure that the boundary trap is cleared, Isaac jets it.
Some toilet paper is then placed in the drain pipe, and Isaac pours a bucket of water down the pipe to simulate a toilet flush. Oliver watches at the boundary shaft to ensure it drains through fine.
Isaac then replaces the pipes and fittings that had to be removed earlier to gain access to the blockage.
