water drip from anti syphon tube SO32

[lateron]

Hi ....... I recently noticed a small amount of water in engine bilge. Having felt for leaks all around seacock, water pump etc and tightened the clips on water lines, it seems to be a small drip from the black tube on the anti syphon valve [ I think the tube exits the valve from the top]. Wondered if there is a build up of pressure or something, only a drip but...Anyone help here?
Thanks Ron

Chasing water leaks on mine became a near full time job! Not had. leak from anti syphon however raw water pump drip took a bit of sorting. Also remember any drip from stern gland runs into engine sump area. When your hot water tank empties into bilges filling cabin full of steam let me know ;D
