Thanks Pragmatic - it was being wasted as it's just too hot to be outside and not in water most of the time here!
Plumbing now all complete. Tile and coping due to start today - probably a weeks worth of work there.
The pump layout has been modified to only be 2 pumps not 3 Originally there was one for spa/pool, one for slide and one for waterfall. Now there slide and waterfall are off the same pump with a 2.5" line.
