    Abstract: 交換可能フィルタカートリッジシステムとともに使用されるバルブアセンブリを開示する。 バルブアセンブリは、中心軸を画定する内部バルブチャンバを有するヘッド部材と、内部バルブチャンバに対して平行に延在しかつ前記内部バルブチャンバと連通する入口通路および出口通路と、を有する。 バルブアセンブリは、入口経路および出口経路を有し、かつヘッド部材の内部バルブチャンバ内において、バルブ部材の入口経路がヘッド部材の入口通路と連通するフィルタ位置と、バルブ部材の入口経路がヘッド部材の入口通路と連通しなくなるバイパス位置と、の間で回転するように適合される、バルブ部材を有する。 バルブアセンブリは、バルブ部材の上面に収容されかつ内部バルブチャンバの対向する面に対して封止するように配置される封止部材を有する。 封止部材は、バルブ部材がフィルタ位置にあるとき、バルブ部材の入口経路および出口経路を流れる未処理流体流および処理済み流体流を夫々密封して隔離し、バルブ部材がバイパス位置にあるとき、ヘッド部材の入口通路および出口通路を大気から密封して隔離することにより入口通路および出口通路の間を流体が流れることができるようにする。

    Abstract: A backwash filtration system comprising a backwash discharge port, a sedimentation collection and separation system, and a final filtration chamber. The backwash discharge port is coupled with a pool filter system and is configured to pass backwashed water from the pool filter system to the sedimentation collection and separation system. The sedimentation collection and separation system has a plurality of sedimentation chambers that are vertically stacked and a plurality of baffles configured to reduce the migration of sediment within the sedimentation chambers. A path for water flow passes down sequentially through each of the sedimentation chambers. The final filtration chamber receives the backwashed water from the sedimentation collection and separation system, filters the backwashed water through a final filtration medium, and passes the filtered water to a water return line of the pool filter system or to a pool of water.

    Abstract: A head for a water filter system having a filter element including a three-way valve member movable between a first position, a second position, and a third position. When the valve member is in the first position, incoming water is directed to the filter element to remove sediment and impurities from the water. When the valve member is in the second position, the incoming water is blocked from passing through the filter element and the valve member. Lastly, when the valve member is in the third position, the incoming water passes through the valve member and not the filter element so that the filter element can be removed and replaced without interrupting the incoming water flow.

    Abstract: A water distribution system having a dual use water treatment unit. The same water treatment unit can be used to treat water supplied from a fill port to a storage tank during a fill operation, as well as water leaving the storage tank for supply to one or more points of water use during a supply operation. When a diverter valve is in a fill position, water supplied to the fill port can flow through the diverter valve and to the water treatment unit for treatment then to the storage tank for storage. When the diverter valve is in a supply position, the water from the storage tank can be delivered using means for pressurizing water to the same treatment unit for treatment, then through the diverter valve and to a point of water use device.
