The BBS Automatic Syphon has been available for over 30 years, building an enviable reputation for quality and reliability, resulting in their specification by many large 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 BBS Automatic Syphon was moved over to plastics. Whilst there is still competition from electronic products for controlling the flushing of urinals, the BBS Automatic Syphon is still the most inexpensive, trouble free and simple to install product on the market. It requires no electricity supply and with no moving parts it requires virtually no maintenance. Whilst available from most UK merchants, they are known to be fitted as far afield as Australia and New Zealand.
