Abstract

A swimming pool siphon for draining above the ground swimming pools. The siphon is comprised of a generally U-shaped tubular construction having two legs connected by a top bight portion restable upon a top edge of the side wall of the swimming pool. The leg ends are supportable upon the ground and the pool floor and have removable closure caps while a fill cap is provided upon the bight portion. A pool leg may also be provided with a flattened end to drain water closely to the pool floor. After filling the fill cap is closed and siphoning commences upon the removal of the closure caps. The drain leg may be bent or rotated for use with in ground swimming pools and leg extensions may be added as needed.

Claims

1. A swimming pool siphon for above the ground swimming pools having a side wall extending above the pool floor and a pool ground support, said pool siphon comprising a bifurcated siphon having two tubular legs acting as a pool leg and a drain leg connected at a bight portion, said bight portion being comprised of a tee junction connected at opposite sides to tubular elbows, each of said elbows being connected to one of said legs, said bight portion having a width exceeding the width of said side wall of the pool and receivable on a top edge of said wall in a rest support position to provide a close straddling-relation of said elbows over said wall, said pool leg having a length at least equal to the height of the side wall so as to be supportable upon the floor of the pool, said drain leg having an outlet extending parallel to the ground whereby the outlet flow may be horizontal and parallel to the ground support, closure means for end portions of each of said legs and removable cap means for said bight portion to provide for filling said pool siphon with water, said closure means being operable to open the legs upon filling of the pool siphon to establish a siphon flow to drain water from said pool, said legs with the bight portion forming a substantially U-shaped construction and being substantially parallel to one another and having a length exceeding the distance between a top edge of the side wall and the pool floor and ground level to provide a three point contact of the pool siphon established by the resting of the bight portion upon the top edge of the side wall, the resting of the outlet end of the pool leg upon the pool floor and the outlet end of the drain leg upon the ground.

2. The swimming pool of claim 1 in which said pool leg is provided with a relatively narrow flattened horizontally extending outlet adapted to be supported upon said floor for draining the water close to the floor.

3. The swimming pool of claim 1 in which said siphon has a substantial rigidity to facilitate said three point contact and support.

4. The swimming pool of claim 1 in which said drain leg is rotatable from a vertical to a substantially horizontal position.

5. The swimming pool of claim 4 in which the said drain leg is connected to a tubular elbow member comprising a relatively rotatable part of said bight portion and said leg and elbow are relatively rotatable from a vertical to a substantial horizontal position.
