The Nanni syphon breaker is designed to be used when the water injection point (the level at which the water is injected into the exhaust pipe) is less the 15cm above the water line.
The syphon is supplied with a U-bend which enables the hoses to run straight downwards. The U-bend can take 13mm, 19mm, 28mm, 32mm hoses. Simply cut off at the required sizes.
It should be fitted at least 25cm above the water line, but no more than 2 meters.
