## Abstract

A water-powered sump pump including a chamber with a water supply inlet, wastewater inlet and a discharge outlet, wherein a venturi is secured within the chamber, and an elbow joint, including a wastewater exit portion and a wastewater entrance portions. This elbow joint is rotationally securable to the wastewater inlet of the chamber to permit securing of the water-powered sump pump in any desired orientation in relation to the sump. In one embodiment the wastewater inlet includes a cylindrical ingress portion with an upwardly facing ridge around a circumference thereof. The securing system of the elbow joint includes tabs on an inner surface of the exit portion of the elbow, each tab containing an inwardly extending rib which rib extends beyond the upwardly facing ridge on the ingress portion of the wastewater inlet when the elbow joint is secured onto the wastewater inlet.

### Claim 4 (depends on 3)

The water-powered sump pump of claim 3 wherein the exit portion of the fixed angle elbow joint further comprises inset cuts extending inward from an end of the exit portion of the fixed angle elbow joint, wherein the cuts form sides of the tabs.

### Claim 5 (depends on 1)

The water-powered sump pump of claim 1 wherein an outer surface of the cylindrical ingress portion comprises one or more grooves extending around a circumference of an outer surface of the cylindrical ingress portion.

### Claim 6 (depends on 5)

The water-powered sump pump of claim 5 wherein an inner surface of the exit portion of the fixed angle elbow joint comprises one or more o-rings which extend into the grooves in the outer surface of the cylindrical ingress portion of the wastewater inlet when the fixed angle elbow joint is secured onto the wastewater inlet.

### Claim 7 (depends on 1)

The water-powered sump pump of claim 1 further comprising a mounting element for mounting to a support comprising a cradle with an arc of 15 to 120 degrees, which cradle is secured to an outer surface of the chamber.

### Claim 8 (depends on 1)

The water-powered sump pump of claim 1 further comprising a float system.

### Claim 9 (depends on 1)

The water-powered sump pump of claim 1 further comprising a filter system secured to piping which piping is secured to the fixed angle elbow joint.

### Claim 10

A water-powered sump pump comprising
a chamber with a water supply inlet, a wastewater inlet, and a discharge outlet, wherein the water supply inlet forms an angle with the wastewater inlet;
a venturi secured within the chamber;
a fixed angle elbow joint comprising a wastewater exit portion and a wastewater entrance portion, which fixed angle elbow joint is rotatably secured to the wastewater inlet of the chamber;
wherein the wastewater inlet of the chamber comprises a cylindrical ingress portion;
wherein the fixed angle elbow joint further comprises a securing system for rotationally securing the fixed angle elbow joint to the wastewater inlet;
wherein the securing system comprises an upwardly facing ridge around at least a portion of a circumference of the cylindrical ingress portion of the wastewater inlet of the chamber;
the securing system further comprises tabs on an inner surface of the exit portion of the fixed angle elbow joint, each tab containing an inwardly extending inset element, which inset element extends beyond the upwardly facing ridge on the cylindrical ingress portion of the wastewater inlet when the fixed angle elbow joint is secured onto the wastewater inlet,
wherein an outer surface of the cylindrical ingress portion comprises one or more grooves extending around a circumference of an outer surface of the cylindrical ingress portion,
wherein the fixed angle elbow joint is rotatable 360° around the wastewater inlet, and
