14.6 ANTI-SIPHON VALVE
- The function of the anti-siphon valve is to inhibit the siphoning action when the engine stops
thus preventing a return of water.
- It is possible that on starting the engine or at certain engine speeds some drops of water may
be seen escaping from the anti-siphon valve.
If so you need to clean the anti-siphon valve: dismantle the water collector at the top of the anti-
siphon valve, then clean the valve with fresh water to remove any impurities.
- Then do the reverse procedure to refit the cleaned component, taking care not to refit the
valve the wrong way round.
- This simple preventative maintenance procedure of the anti-siphon valve is recommended
to be carried out once a year.
