Automatic Syphons are WRAS approved and have been available for over 30 years. Known for their quality and reliability they are a favourite of many OEM’s for use in their cisterns.
Originally the syphons were manufactured from mainly copper and brass, but with major advancements in the availability of the raw materials and injection moulding techniques, the manufacture of the Automatic Syphon has moved to plastics.
All Automatic Syphons are supplied complete with two rubber washers and back nut. Each automatic syphon is fully tested before leaving the factory.
