ABSTRACT:
Apparatus is provided to move a fitting relative to a hole provided through the wall of a water main or the like. The apparatus includes a housing provided with an internal chamber communicating with the atmosphere through two openings. The housing is mounted on the water main such that a marginal portion of the housing about the first opening surrounds a fitting positioned in such hole. A pivotal member is sealingly mounted in the second housing opening for pivotal movement relative to the housing. A rod slidably penetrates a throughbore provided through the pivotal member, and has one end arranged to move toward and away from the hole. This rod end carries an adapter which may be engaged with a fitting. Thereafter, the rod may be selectively manipulated to move the fitting relative to the hole.
