Abstract
A float controlled valve syphons water out of a swimming pool cover. The syphon valve includes co-operable male and female valve members disposed for mutually relative movement to bring them into and out of mutual engagement to thereby close and open flow communication through a syphon discharge passage formed in the male member. A float body is coupled to one of the said members for effecting the engagement and disengagement in response to the level of the water in the swimming pool cover. The male valve member is tapered at the forward end to facilitate engagement with a central recess in the female member. The female member is formed of more yielding material than the male member and has a thin walled portion receiving the male member and of sufficient flexibility to envelop dirt particles at the male-female member seal.
