ABSTRACT:
An underwater fitting is provided to allow a controlled leak of water into a suction line between a filter installation and an automatic pool cleaner. The fitting is T shaped with the head of the T in the suction line and the leg of the T controlled by a tapered mandrel in an orifice which are adjustable to vary the effective orifice area. The mandrel is spring biased so that is can be pushed back in case of a complete stoppage of flow from the cleaner.
