John, I had not heard that. I discussed it with the WM people and with the head yard guy where I get work done that I can't do myself. Someone did mention that one did stick one time but they said they had a bunch of gunk in the bilge. You make a good point. I wonder if I could raise the discharge hose a bit so less water would be there to overcome for the pump. I should think a 2000 gpm pump would have the power to overcome the head pressure in the line. It would be interesting to survey to see what capacity bilge pumps are in the various years of C27s. Mine is a 1988. Dick Schmidt Greenville, NC

There have been some sad stories in both the Catalina Mainsheet magazine and various threads on the various C27 e-mail groups. So, if you are using something similar to a rule 2000, like I have: Rule had the following FAQ before their web site was changed. Q: Can I install a check valve on the discharge of my bilge pump to keep water from running back through the pump? A: No. A check valve should NOT be installed in the discharge line. As submersible pumps create very little discharge pressure, they may not be able to overcome the resistance or weight of the column of water or weight of the check valve flapper or poppet itself. The pump may therefore have an airlocked condition. ------------------------------------ Yahoo! Groups Links
