Abstract: A safety cover having a filter and an optional chemical dispenser, that covers and existing faceplate on a water vessel having a closed loop piping system and water pump. When the cover and filter cover an existing faceplate the cover and filter increases the vacuum on a suction line leading to a water pump by less than 5? Hg. The chemical in the dispenser releases in a metered dose of a substance having antimicrobial properties and the dose is in a sufficient amount to inhibit a growth of a microorganism in at least a segment of a water vessel. The combination of cover, filter and chemical chamber are disposable, or the filter is replaceable and the chemical in the chemical chamber is replenishable. The cover with filter and chemical chamber or just the cover and chemical chamber, or just the cover and filter are retrofitable to any existing faceplate on a water vessel having a closed looped piping system and a water pump.

Abstract: A fill and drain hydromassage water vessel having an acrylic surface, resin and fiberglass backing and antimicrobial in components of the water vessel system. The antimicrobial reduces bacteria in the water vessel system.

Abstract: A fill and drain jetted hydromassage whirlpool bathtub having a tub made of acrylic, resin and fiberglass. The whirlpool bathtub having a water system with drain down water features and components made of a material having an antimicrobial therein. Bacteria reduction occurs in the water vessel system where the antimicrobial is therein. The non-porous acrylic surface, the drain down features and the antimicrobial surfaces provide an economic sanitation level for hydromassage jetted whirlpool bathtub.

Abstract: A method to make a whirlpool bathtub where bacteria growth is inhibited or bacteria is reduced, after tub drain down and between electrical system activation.

Abstract: A device and method to inhibit bacteria in a whirlpool bathtub and its closed looped plumbing system between each whirlpool bathtub drain down as well as during each whirlpool bathtub use. In addition to combining a high flow antimicrobial chamber with a suction device, the present invention incorporates safety features.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising incorporating an antimicrobial agent in some or all segments of the piping of the closed loop water system and/or the air piping.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising improvements to U.S. Pat. No. 6,395,167 and incorporating an antimicrobial chemical dispenser.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising improvements to U.S. Pat. No. 6,395,167 and incorporating an antimicrobial chemical dispenser.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising improvements to U.S. Pat. No. 6,395,167 and incorporating an integral top fill antimicrobial injector not in the prior art. The system also practices the adding of antimicrobial additives to the water vessel system components, which include but are not limited to the system's piping, pump, jets, acrylic sheet and fiberglass/resin reinforcements.
