A device which will allow removal of water from the pipes and associate equipment servicing a swimming pool without partially draining the pool consisting of a first member equipped with means for water-tight engagement with an outlet in the sidewall of a pool structure and a second member equipped with a standpipe. When the first and second members are tightened into water-tight relationship, a vent is provided from the outlet in the sidewall of the pool to the outside air. The water in the pipe associated with the outlet can then be removed without the necessity of draining any water from the pool.
