-------- Original Message -------- Subject: Re: catalina27-talk: storage and gas mileage & bilge pump check valve Date: Fri, 29 Jun 2007 08:33:10 -0500 From: John Oppenheimer <[email protected]> To: [email protected] Very bad things can happen with a bilge pump check valve. 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!
