Abstract: A suction relief apparatus for relieving suction at a suction connection of a swimming pool or spa having a main valve member movable from an open to a closed position to relieve suction at the suction connection in the event of a blockage of the suction connection in the pool. The main valve remains closed until a reset valve is opened, at which time a spring returns the main valve to the open condition, enabling suction to resume at the suction connection of the pool. A switch responsive to increased suction indicative of an obstruction may be utilized to deactivate a suction pump motor. In an alternative embodiment, a frangible member may replace the main valve and reset valves to open a connection to ambient air atmosphere in the event of increased suction in the suction line resulting from an obstruction at the suction connection in the pool.

Abstract: A training device is worn by a user for strengthening and training the legs. A belt extends around the waist of the user. An elastic strap has two forward runs and two rearward runs. Each of the forward runs secures to the belt at an upward end along the front section of the belt. The forward runs extend down to a loop which receives the user's foot. The rearward runs extend from the loop back to apertures located on the back section of the belt.
