I did see another interesting thing
You guys use something that looks like Smurf tube (type ENT), outside. That is dry only here.
Greg, that looks like either a plumber or an apprentice installed that.
That stuff is known as Bettaflex here, or flexible medium-duty PVC conduit.
It's used by people that can't use a bending spring on rigid PVC conduit.
Reason I say a plumber may have been involved is that that saddle to the right of the socket-outlet is a pipe saddle made for 3/4" pressure pipe, which is bigger than 20mm conduit.
