[C320-list] Anti siphon parts

[David J Cardoza]

I "Blew" mine a couple of years ago except in my case it popped the hose clamp off the loop and sprayed water all over the place.  If you would like a demo have water in the shower sump set the Y valve to shower and close the thru-hull the pump pressure is very impressive.

Herb:  Are you talking about the rubber piece in the cap of one of the 
Marelon vented loops?  These are made by Forespar and I believe 
replacement cap assemblies are available from West Marine, and probably 
from Defender and other suppliers.  Search the WM site for part number 
594127.  The Forespar part number is 903002 according to the WM web 
site.  As far as I know there is only one size.  My recollection is that 
  the replacement cap includes the rubber valve insert, and that you 
can't purchase these separately.

I'm curious what you mean by "blown."  I've had these things stick open 
due to salt or mineral crystals, but often a good rinse with fresh water 
gets them working again.  There should not be enough back pressure in 
any of your systems to actually damage one.
