[C320-list] Need advice--raw water anti-siphon valve

[Dave Ouimette]

Guy, thanks for the advice. I take it you have not had a problem with seawater spraying/dripping all over your Perkins even when the boat is well heeled? As Jeff Hare mentioned, on newer boats the valve is high above waterline in the port lazarette whereas it appears to have less clearance above waterline on boats with Perkins engines.

I have a 1994 C320 with a Perkins engine.  The raw water anti-siphon valve is
mounted in the engine compartment on the port side.  As high as possible on the
side of the fridge.

It should be easy to check if it's been moved.  It needs
to be in the raw water line between the raw water pump and the heat exchanger. 
When you remove the cap, if the siphon is broken, it's high enough.  

I did
have to replace the one way valve in the anti-siphon valve 10 years ago.

I have a 1995 C320 with a Perkins engine. At some point
in the past the raw water anti-siphon valve was removed. From the Catalina
owner's manual it appears the valve was installed by the factory in the engine
compartment on the port side. At that location it doesn't look like it would be
much above the waterline, but I don't have an exact measurement. I am trying to
find out if owner's of boats with Perkins engines have had problem with valve
leakage or other issues and may have re-routed the valve to a new location, or
perhaps abandoned it altogether. Please help...
Thanks. Dave
