The tub will come with a 6' length of blower hose attached to the tub. This connection should not be removed, but the blower hose can be cut in the center of one of the flat spots to create a length of hose to attach the PVC to the air output fitting on the blower. The rest of the distance between the blower and the tub can be made up of 1" diameter PVC rigid or flex pipe. When making 90 degree turns with PVC two 45 degree fittings should be used to prevent restriction of air flow. Clamps should be used to secure blower hose at the connection points.
