Drain Addict — “Blocked Drain 927” — Jetting a blocked sewage system from within a short crawlspace
Oliver (Drain Addict @ YouTube; Drain Go) starts by jetting though an inspection opening, which seems to be for a sewage system’s boundary trap, that he had to dig through some grassy soil to access.
He then moves to a different location to access the drain pipe, via a small external hatchway that leads to a very short crawlspace under a building. To the left of the small door is a drain pipe that was apparently patched at some point with another fragment of pipe. After the patch is removed, an existing drilled circular hole is revealed in the wall of the pipe. The jetter is used through this access point to pop the blockage.
After the jetting, the camera is used to inspect the state of the pipe, and some remaining traces of root infiltration is observed. Some more jetting is done to clear away the remaining roots. The drilled access hole in the pipe is then patched over once again with a fragment of pipe.
A toilet paper flush test is performed and observed at the original inspection opening, which demonstrates that the blockage was cleared and the system is draining once again.
