2733. Witham, W. H. Feb. 2. Water - waste prev e n t e r s, siphon-discharge. The discharge pipe B, which has a seal D in its length, is covered by a fixed bell A, into the crown of which passes a helical air pipe a. As the cistern fills the air is compressed in the pipe B. When this pressure is relieved by a hand - valve E, the water overflows the crown of the siphon and the flush is started. The flow is broken by the entry of air through the pipe a.
