I built this one and have used it for 2 years, happy with the results, and couldn't beat the price $3.00 or so.

: Yoyageurs,

: My next crappy challenge is to try and make my own hand bilge pump.
: Those hand pumps seem to have a membrane inside, that has a pinhole.
: With all the pvc and alu leftover tubes that stand in my way, perhaps I
: should be able to glue out sthg.
: Also, do you turn the exhaust pipe end overboard over the coaming, or do you
: run it thru some hole in the hull, at a lower level?
: I hold nothing against electrical pumps, but most have a low capacity.
