Hi gurus,

Reckless as I was, I dropped a plastic cap of a water bottle into the pipe of the fresh water tank of my boat.

I used the endoscopic camera to locate the cap down the pipe. Not sure if I lucky that it didn't go all the way through the tank yet. (See attached picture)

The cap is sitting about 1.7meters down from the deck fill.

Do you have any suggestion what would be the best course of action here?

Thank you very much in advance for your advices!

Kind regards,
I'd leave the camera to see what you are doing, then get some clear, flexible 1/2" hose, and connect one end to a shop vacuum. Turn on the suction, and chase the line into the hole and try to capture the cap using the shop-vac to suck onto it.
Now time for a tethered cap for that fresh-water inlet.
Tethered caps are designed to irritate you enough that you cap the opening.
Be sure to get one in a loud color. :)
