The Dudley Turbo 88 Adjustable Syphon is an ideal replacement for syphons in most low-level lever operated cisterns. Its 2-part design enables the syphon body to be simply removed from the cistern leaving the white downleg in position. Servicing can then be completed in under 5 minutes without having to disconnect the water supply and dismantle the cistern. The Turbo 88 is a WRAS approved, market leading flushing syphon that incorporates a patented Dudley Duoflush facility. This delivers a water-saving reduced flush when the cistern lever is depressed and held down. When the lever is depressed and released, the Turbo 88 Duoflush delivers a full flush that is as reliable as ever. 42mm outlet. 6/7/9 litre convertible. Adjusts from 7.5 to 9.5.
