What is this

[[185615]]

Whilst replacing sanitary pipe I’m my heads, which runs the length of the lockers behind the loo and the wash basin.
Bit of a struggle to get the old calcium blocked pipe during which it fell down from the top of the lockers, cannot see anything it attached to.
It has pipes running it’s length rather like a Lancashire boiler..
