Low Profile Bilge Pump

aero3113

Anyone ever see this bilge pump? I’m thinking about installing it at the lowest point in the bilge at the drain plug. The original will be a backup if this one ever fails. I can use a “Y” adapter and plumb it into the existing hose. Thoughts?

Been looking at reviews on it and they aren’t the best……

I have a diaphragm pump with a hose that goes right into the garbord plug area to get that last bit of water out. Works perfect.

I just use a small 2 1/2 gal shop vac.  The problem is that last bit of water also has other junk in it that would likely clog up the pump.  I actually just replaced my bilge pump.  One item i was going back and forth on was a fully automatic pump vs one with an attached float switch. I decided to go with the float switch.  The automatic ones turn on every two minutes to check for water and it gets a little annoying and it uses up battery.  The float does allow more water to build up but it will still work off of a switch manually at the helm.  I was also able to move mine back a little and get it to pick up more.  i also bumped up the size.  I went from 950 gpm to 1500gpm.  In this case bigger is definitely better.  Water shoots out the side now about 4ft.

I remember you installing that. I would like to have something that’s automatic. I like the idea of having 2 pumps incase one fails.

Yeah the diaphragm pump doesn’t move much water.

Have used this one for a year or so, has been great having a super dry bilge.. https://www.amazon.com/SEAFLO-Dry-Bilge-System/dp/B07V4G41K4

What blows me away is just how much water goes into the bilge from rain.  I am on a lift.  Can leave a boat that is perfectly dry and come back to one with 20 gal of water in it.

You ever think about adding a 12V timer to it? Would make it automatic.

I bought one last year and didn’t install because my bilge was rarely wet! I solved virtually all of the leaks in the various fittings plus canvas. Worst offender was the fresh water hook up.

I also installed a diaphram pump and plumbed it to the sink drain.  I have it wired to the bilge pump so they both run at the same time.  Just to keep the bilge as dry as possible.  I love it.

I think I’m finally going to get around to installing a second pump in the bilge. What size is the discharge hose on our Rinkers? Is it 3/4? I’m going to use a “Y” adapter to tie into the existing hose.

@aero3113 wouldn’t the y cause some water to backflow to the other pump? I guess you are planning a high loop in the hose?
