My wife is trying to convince me that I don't HAVE to take things apart that aren't broken just to figure out how they work.
So, in this nod to her wisdom, I'll ask the question here first.
Our raw water
intake for the engine
has a seacock that has two hoses coming from it. The main hose is about 1.5" id and the second one, on the side, is probably 1/4- 3/8 "id. The main hose goes to a typical strainer, then to the Seafrost, then to the engine heat exchanger
The smaller hose runs to the top of a Vetus anti-siphon valve that has two other hoses attached. One, the input to the valve, comes from the heat exhanger output. The output from the anti-siphon valve goes the muffler
How does this anti-siphon valve work? What does the small line from the seacock to the anti-siphon do?
Shouldn't I just take the damned thing apart and see for myself?
Thanks for the enlightenment,
