ABSTRACT:
A device for isolating piping associated with a swimming pool for isolating a piping system associated with a swimming pool in order to reduce the amount of chemicals required to treat the piping system, and further to prevent mixture of chemicals within the pool with the treatment chemicals. The isolating device includes an adaptor head having an outlet configured to encircle a conventional swimming pool drain and an inlet configured to receive the end of a conventional vacuum hose. The adaptor head defines a substantially cylindrical configuration having a diameter at least as large as the particular drain with which the isolating device is being used. A plurality of screw bosses is provided on the interior of the adaptor head proximate the outlet to cooperate with the threaded openings provided in the drain for securing the drain grate. The adaptor head includes a cylindrical wall and a cover plate, the cover plate being removably mounted to the cylindrical. The inlet is carried by the cover plate and is configured to be closely received within one end of a conventional vacuum hose. The cover plate carries a relief valve for pressure equalization within the piping system, and especially within the isolating device. An attachment member is provided for the attachment of an elongated handle member. The attachment member is similar to conventional attachment members carried by conventional vacuum heads. The handle is attached to the adaptor head for manipulating the adaptor head to a position over the drain. When the isolating device is not secured to the drain as described above, the handle may be used to apply pressure to the adaptor head to maintain its position.
