Every cracked pipe clip draws the same one word comment
Somebody will write sinkhole under your video, and your reply is read by everyone who arrives afterward.
Roots through a clay joint. A cast iron pipe with the bottom rusted out of it. A belly holding water under a slab. Nobody outside the trade has seen any of that, and the format explains itself without narration or editing.
Post it here and one word turns up underneath, usually before anyone has read the caption. West central Florida sits on soluble limestone and people who live in Hillsborough County know it.
Have one standard reply and use it every time. A plumber can say what the camera shows and what the pipe is made of. What the ground is doing belongs to a licensed professional engineer or a geotechnical firm, and the Florida Geological Survey publishes general material for anyone who wants to understand the geology.
Turn the comment off the ground and onto the pipe. Somebody who types that word usually wants to know whether their own line is doing the same thing, and a plumber can answer that: how long a camera run takes, what it can and cannot see, and what the drain material under a house of their vintage is likely to be.
Name the decade every time you post one. Cast iron under a mid-century slab in Temple Terrace and plastic under a newer Riverview build fail differently and on different timelines, and a viewer sorting for their own house sorts by age before anything else.
