Water cannon swivel
Definition
The rotating bearing assembly that lets a child aim a water cannon up, down, left and right; the most failure-prone mechanical part of any interactive splash pad feature due to constant kid use and grit ingress.
The swivel is the heart of any aimable water cannon. It includes a sealed bearing, a flexible water-supply hose routed through the rotation axis, and travel-stop pins that prevent kids from over-rotating and tearing the supply hose loose.
Swivels fail in two ways: bearing seizure (from grit and chlorinated water creeping past the seal) and supply-hose abrasion (from rotation cycles wearing through). Quality manufacturers (Vortex, Aquatix, Waterplay) rate cannons for 50,000+ rotation cycles. Cheaper imports fail in a single season. Replacement is usually a top-down component swap without disturbing the cannon's structural mount.
