I hate disagreeing with Josh or Edd as I respect you guys so much. But my opinion is that if you need volume pumping, something is dramatically wrong. If you're not on the boat, it will sink anyway. If you're on the boat, it may give you more time to find the leak, but my centrifugal pumps tend to clog, bind up, or at least never pump to the stated volume. I'd rather have a 300 gph pump I think will actually pump that much than a 1,000 rated gph pump that ultimately I don't think I can fully rely on that actually delivers 500 gph.Centrifugal pumps tend to rely on numbers without lift, where diaphragm pumps are not affected nearly as much.Just my $.02 worthBruce Sent from Samsung tablet. -------- Original message --------From: Josh Muckley via CnC-List <cnc-list@cnc-list.com> Date: 6/23/20 10:16 PM (GMT-05:00) To: C&C List <cnc-list@cnc-list.com> Cc: Josh Muckley <muckl...@gmail.com> Subject: Re: Stus-List Bilge pump question The diaphragm pumps are great for getting the very last drops but they tend to be relatively low flow rate. I would suggest that you consider adding as high of a capacity pump as will fit and have it run on an automatic switch. You could have them run simultaneously but really having just the new high flow pump run as the primary pump is sufficient. Once the bilge is pumped, you can pump the dredges manually with the diaphragm pump.For high flow you're basically going to get a centrifugal pump. I replaced the original Rule with another pricey Rule pump which failed withing 3 years. I replaced it with a Walmart Atwood Pump which failed within 3 years and replaced it with the current Johnson pump. I'm not hopeful that it will last more than 3 years.Josh Muckley S/V Sea Hawk 1989 C&C 37+Solomons, MDOn Tue, Jun 23, 2020, 16:02 Matt Wolford via CnC-List <cnc-list@cnc-list.com> wrote:Listers:
New topic. My boat came with a really nice diaphragm pump for the bilge, but it operates on a manual switch. I was going to change the switch and install a sensor in the bilge to make it automatic, but it occurs to me that having redundancy is a good idea for this application. Which pumps to people like for placement in the bilge? I picked up a water witch sensor, so I don't need an automatic pump. Thanks in advance for suggestions.
