  • Negative or vanishing edge for spas and/or hot tubs
    Patent number: 7836526

A reservoir (120) holds a constant head of water to provide to a pump (112) and also allows for the holding of increased amounts of water displaced by users who are using the hot tub (100). Water flowing over the vanishing edge (110) flows into the catch basin (102) and thence to the reservoir (120) and pump (112) where the water is recirculated into the spa (100).
