[C320-list] Anti siphon parts

[Scott Thompson]

I found this quickly on Defender's web site by searching on the Forespar 
part number.  There is also a close up photo there, which shows the 
"duck bill" valve -- the little rubber insert -- inserted into the cap 
upside down!  The correct installation has the pointy end pointing down.

The bad photo is here:

I will try Defender.  In the mean time I bought some cork stoppers that should work as a  temporary fix.   Am going out for the weekend and don't have time to find them before that.

>> Does anyone on the list know where I can obtain parts for anti-siphon.  Yesterday one of the rubber cap plugs blew when I was de-winterizing.  I can't find the plug and don't know where to purchase a replacement.  If there is a temporary fix I'l take that too.
