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. The cover having a filter prevents hair from becoming entrapped in an existing faceplate, as the filter creates a barrier between the inventive cover and the existing faceplate. The cover also has various means to keep the cover secured over the existing faceplate until a user decides to removes it.
