Two days to go and I still haven't seen (among others...)
The
brick in the tank
The butt crack
The near-empty roll (with 1 sheet remaining)
Plunger action
A toilet auger in action
Macro of a fill-valve (in tank - usually on left side)
Overflowing toilet
A floater
(thank goodness the low denominator folks
didn't sign on for this one - well, one did. No comment!)
Macro of an angle stop (on/off handle at wall)
Flapper macro
One of those new power flusher units
(compressed air tank in water tank)
Broken (smashed) toilet
Kids putting things in toilet (usually never seen but often
found later, after you receive the plumber's bill!)
and of course the model on toilet, shot through the keyhole, shot!
Need more ideas?
