Re: using multiple bilge pumps on one outlet...It generally is not done.
The pumps do not come with non return valves, so even if you combined all
the hoses after high loops, if the through hull partially clogged, the water
would return to the bilge through the other pump(s). You could install
valves, but they restrict the flow and clog and are basically not reliable.
I think the only practical alternative is multiple through hulls.
