Parts list

Not sure how it all goes together?
The plumbing diagram shows every pipe, size and fitting for this design.

Quantities come from the plumbing for this design, the same as the plumbing diagram. Pipe includes 10% extra and each fitting line has 2 spares, because a missing elbow costs more to post than a spare one. Measure your own runs before you order. Hot tub and pool pipe is imperial (1.5″, 2″, 2.5″) in the UK as well as the US.

This is for a private home. We only design domestic hot tubs and pools, not commercial or public ones. The control room will sit below the water line. The pumps need to be lower than the water so they stay full and primed.

Distance from the tub to the control room
