The present invention relates to a tree watering apparatus that can be used to irrigate the base of a tree and to protect the roots thereof. The present invention comprises a semi-circular ring having a bottom half that serves as a root barrier and a top half that serves as a barrier to retain water around a tree while the water percolates to the root system of the tree. A distribution tubing is attached to a water supply and directs water around a tree which is then retained on the ground around the tree by the top half of the present invention while it percolates into the ground. Water that percolates into the ground is then directed to the root system of the tree by the bottom half of the present invention that is buried.

The flowmeter of the present invention is primarily used in swimming pools and is configured to deactivate a swimming pool pump when the drain in the swimming pool is blocked or covered. Swimming pool drains are often blocked or covered by the body of a swimmer. When the drain is blocked or covered, the pump creates substantial suction force that entraps the body of a swimmer against the drain. By deactivating the pump when the drain is blocked or covered, the flowmeter of the present invention serves as a safety vacuum release system that prevents entrapment of a person by the drain of the swimming pool.

The present invention is an air evacuation apparatus that prevents the accumulation of air inside a swimming pool or spa filter by allowing any air to be removed from inside the filter every time the swimming pool pump is turned on. By allowing air to be removed from the filter, the present invention prevents the build-up of dangerous levels of potential energy caused by compressed air inside the filter that can lead to the violent separation of the filter. More important, the air evacuation apparatus of the present invention allows air to be safely and automatically removed from inside of the filter without interfering with the functionality of the filter.

A vacuum relief safety valve includes a housing defining an inner chamber and attached to the suction-side of the swimming pool or spa pump. An air inlet aperture is formed in the housing so as to be open to ambient air. A sealing element is disposed within the housing and biased against the air inlet aperture by a spring so as to effectively seal the inner chamber of the housing from ambient air. When a maximum allowed vacuum level within the pump is exceeded, such as when a swimming pool drain is obstructed, the sealing element moves into the inner chamber and opens the air inlet aperture causing the pump to rapidly lose its prime and enabling removal of the entrapment. Simultaneously, the movement of the sealing element provides electricity to a control circuit which shuts off power to the pump.

An improved motor-driven pump is provided for delivering a flow of water in a swimming pool or spa environment or the like. The improved pump includes a motor mounted within a motor housing having a seal plate mounted at one end thereof. The seal plate carries a shaft bearing for rotatably supporting a drive shaft having an outboard end connected to an impeller disposed within a pump chamber defined cooperatively by the seal plate and a volute housing mounted thereon. A primary seal assembly includes an axially spring-loaded dynamic seal ring carried on the drive shaft for rotation therewith and for running engagement with a stationary bushing carried by the seal plate. A secondary seal assembly is positioned axially between the primary seal assembly and motor bearing, and includes at least one slinger disk for radially outwardly slinging any water leaking past the primary seal assembly through a vent chamber.

A suction fitting for use in a water circulation system, the fitting having a perforated body that is mounted to permit fluid flow through both front and rear perforated faces, and thereby minimize the possibility of complete blockage of the fitting by entrapped hair or skin. Operation of a circulating pump is controlled to prevent damage to equipment and property and also to minimize the possibility of serious personal injury or death. The suction fitting further includes a suction tube for connection to the pump, for circulating water in the tub or spa back through jets in the tub or spa, and a pressure sensor line connecting the water in the tub or spa to a water level sensor. The front face of the perforated body has a number of grooves, to provide fluid communication between the pressure sensor line and the suction tube, through one or more front-face perforations. When flow into the suction fitting is blocked, a reduced pressure is sensed immediately behind the front face of the perforated body, through the pressure sensor line and the grooves in the front face, and the pump is disabled to prevent damage or physical injury.
