The field to which this invention pertains is above ground swimming pools. This invention has the ability to decrease the amount of time it takes to vacuum and winterize above ground swimming pools significantly by overcoming existing, numerous equipment problems that are currently present. For example when vacuuming or winterizing above ground pools in the past it has been noted to be inefficient due to the inability of conventional equipment to decrease air intake and therefore increase the speed of water circulation in the system.
This invention relates to a manual operable tool to assist in the transfer of water from a swimming pool. It is common in devices for transferring water while draining swimming pools to sustain water flow efficiency only until the time that the water line reaches the low end of the skimmer box. As it is necessary to continue draining the swimming pool as quick and expeditious as possible without interruption, using present equipment of this nature is however inefficient because it withstands only limited amounts of air before eventually succumbing to complete faltering which results in a complete loss of water flow. They are moreover unsatisfactory in that there must be sufficient and consistent water flow for complete pool drainage.
“I have found that these disadvantages may be overcome by providing a drain head secured to the drain hose inlet cuff located on the swimming pool floor at the proper location and a rubber seal secured to the drain hose outlet cuff in a way that when employed onto the skimmer box bottom plate inlet opening it provides for a much tighter connection allowing for a more consistent and quicker transfer of water.

Winterizing or vacuuming the swimming pool with the use of older more conventional methods proves inefficient as they are very time consuming and include much un-needed work. The embodiments illustrated with this invention begin with the drain head which comprises a plastic incased iron weight to secure the drain head so as to allow minimal or no movement while the drain head is in its working position. The drain head also comprises a detachable filter basket that connects to the inside. Held in place by two twist lock pins the filter basket collects any debris from attracting water circulating upwards from the drain head bottom that may otherwise enter into the drain hose. Bottom support requirement for the drain head comprises four half oval shaped, extended wall locations providing equal and balanced support. In route to the skimmer box the flow of water passes through the drain hose which consists of two end connecting cuffs by which the drain head and the seal connect. Connected to the skimmer box bottom plate inlet opening providing an air tight connection and making the difference as compared to older equipment of this nature consisting only of a single hose, is the drain hose seal with its rigid firmness providing a smooth and very swift water flow to the water pump.
When vacuuming the system works the same as with winterizing. With the addition of the seals air tight connection providing a much greater vacuum movement you can see the surrounding debris been drawn towards the vacuum head with increased efficiency. Using the vacuum hose and vacuum head are the only equipment changes.
The seal cuff an added attachment to be used essentially when vacuuming the swimming pool attaches to the vacuum hose outlet cuff by threaded adjustment, locking the seal into position in case of hose movement. It consists of a hollow interior, looking similar in shape but larger to that of the seal. This invention has proven to greatly reduce the amount of time it takes to winterize or vacuum above ground swimming pools, as compared to older more conventional methods.
