Bilge Pump - Wet line Distributor

[Navi2016]

Hi All

I am in the process of redoing the bilge pumps on the boat, and I don't want to add more holes in the hull. Right now I have 2 1.5in bilge thru hulls, and I would like to add some extra pumps. So here it the idea

I have deep bilge,
- old style stuffing box, drips a bit as required
- all 3 sinks pipe to the bilge
- shower piped to the bilge

I plan to install 2 Whale Gulper IC bilge pumps in the lower part of the bilge, each pump pickup will be approx. 8 inches vertical from each other. so they will in fact start in stages if required. Ratings are 5gals / Min

I plan to install a Whale Gulper IC shower pump, this is also rated at 5gals/min

So between them, I will be running 3 1.0in bilge hoses towards the true hull, I have enough elevation that I can create a loop prior to getting to the thru hull.... then I want to use a water manifold at the thru hull. I found this on line, it has (4) 1 in ports to a 1.5in out. this will be located at the thru hull fitting

So..... What's wrong with this idea? I am sure I am not the first person to get the idea.... So how can I do this better?


The other 1.5 thru hull is for a 4000g/hour main bilge pump located a yet another higher elevation in the bilge.

Thanks for the feed back
