Friday again, plumbing today.

The tap and waste are fitted to the sink.

Waste pipe is installed and the hot/cold feeds are connected.

The Jabsco Par Max 2.9 temporarily installed, you can see the waste doesn't exit directly behind the sink (as this area will be tiled so un-get-at-able if it starts leaking), instead it runs back into the saloon under the bed and then out (right of picture) next to the shower waste.
