In a jetting operation, into which manhole is the jetter typically lowered?

Explanation:
In jetting, you want to direct the cleaning action toward the end of the line where you can easily retrieve the loosened material. Lowering the jetter into the downstream manhole lets you aim the high-pressure jet upstream to scour the pipe, while the natural flow carries the loosened debris toward the downstream end. Having access at the downstream manhole makes it straightforward to collect and dispose of the debris and keeps the operation under control. Entering from the downstream end also aligns with the outlet end of the system, which aids efficient cleaning and retrieval.
