In addition to our market-leading range of 2-part Dudley Turbo's, Thomas Dudley manufactures a wide range of one-piece plastic WC flushing syphons, all of which can be used with confidence. As with every Dudley product, our plastic syphons undergo exhaustive and rigorous testing, which means that when they are installed, reliability and durability come as standard.
