I recently pulled a bone headed maneuver. In short I managed to block the vented loop on the engine
anti-siphon. The engine
flooded, to the brim. Luckily it was in fresh water
and I seem to have recovered with no lasting ill effects except to my ego.
Having had the vital importance of the anti-siphon deeply impressed upon me I am now struck with how we install and forget this device. Surely these can eventually fail to gent, they are not fool proof and 100% reliable. Even if very highly reliable the consequence of failure is pretty nasty.
My long awaited question:
Is there some kind of alarm
or other warning device to monitor
their operation? Some way to assure they are working?
I am imaging a low pressure or pressure differential sensor, if this senses a low pressure (lower than atmospheric) it closes/opens a contact. Might be useful on head
anti-siphons as well.
