[C320-list] Anti - Siphon Loop

Hi

My pump would not self prime when I had that layout on hull 925.  The dealer 
solution was to put a hose on the shower drain outlet (with Y valve on 
shower) and force water into the pump which then picked up the prime and 
generally held it for our summer season.  I would repeat the process each 
spring to re prime.  Only do this if you have made sure that there is no 
debris in the filter etc.  Mine was full of junk when delivered.  My MKII 
has the same issue with the shower drain even though it is plumbed 
differently.  The same solution works in the MKII

Regards

Jerry Brown
