Installing Your Spa
Remote Equipment Only - Making Plumbing Connections
Plumbing connections and stub-outs are clearly labeled to correspond between the spa and
equipment pack. Use PVC pipes & fittings that are “Schedule 40 Pressure”.
Pipe Diameter: 2.5” Filter / Jet Suction 2.0” Filter / Jet Return
NOTE: A two-pump spa will require eight plumbing connections (four at the spa and four at the
equipment pack). A one-pump spa requires only four connections (two at each end).
1. Measure and cut the PVC pipes using a hacksaw or pipe cutter. Sand the inside and
outside of the cut smooth.
2. Dry fit all pipes between the equipment pack and spa. Look at the layout to make sure there
will not be any traps. Also, if the equipment pack is above the water line of the spa, you will
need to install flapper-type check valves. Depending on how far above the water level the
equipment pack is located - Please refer to local codes.
NOTE: Keep access area available for any future service work requirements.

NOTE: The standard stub-out location is beneath the spa steps.
3. Swab colored PCV cement primer generously over the pipe ends and fittings.
4. Swab blue PVC solvent glue over the primed areas at the pipe ends.
5. Slide the glued pipe ends into the fittings and twist slightly.
Hold for about 30 seconds, then release.
6. Allow all glued connections to set completely before filling the spa with water.
For optimal performance,
the equipment pack
should be positioned
below the water line
