Abstract: A system for filtering water in a spa that provides safety and greater filtration. The system may include a filter secured to a core. The core may include first and second cages with a plurality of openings allowing water to freely pass through the filter and core while preventing larger objects from passing through. The first cage may provide an orientation feature to position the filter in one direction. The second cage may hold mineral cartridges. The core may be secured to a fitting that is secured to the suction line of a spa via a ratchet like engagement feature. The fitting and core prevent back out of the core unless manually overriding the arm on the core which engages fins on the fitting. The filter may be removed and replaced while the core remains in place providing safety to the user. A cap secures the whole assembly into place.

Abstract: A system for heating a pool or spa. The system may include a circuit for interrupting the power supply to a heating element of the pool or spa. A thyristor may be used to vary the voltage supply to the heating element, such as by use of a variable resistor, capacitor, and a triac. The system may adjust the resistance on the variable resistor to control to voltage supply to the heating element, allowing a larger heating element to be used more efficiently.

Abstract: A system for providing an in-ground installation of a portable spa using a Spa Vault assembly.

Abstract: A bathing system with a molded shell has hollows in the shell. A canister installed in each hollow with jets mounted upon the front jet plate of the canister. The canister is of simple construction that is mounted in a hollow and is removable and interchangeable for easy upgrading and repair of the bathing system.

Abstract: A modular spa with an integrated manifold that has telescoping structure that permits easy insertion and length adjustment for installation between water inlet and outlet lines.

Abstract: An upgradable spa or bathing system where jets are mounted on jet panel that covers a pod. The jet panel and pod enclose the air and water supply systems to the jets, which are configured with a manifold system to easily release the jets and the jet panel for repair or replacement of the jets. A separate upper panel covers the upper portion of the pod and includes an attachment to the spa shell and a headrest. The jet panel is held in place by engagement with structure on the shell and the upper panel and may be replaced without also replacing the head rest or the shell attachment of the top cover.
