I installed a Seagull filter on our boat a few seasons ago (pricey - but very effective). We have a foot pump drawing water from the tanks to the galley sink. I bought a 3-way valve from US Plastics and plumbed the filter so that it could be set to the pressure side, or the manual foot pump side.
The rather large charcoal filter creates quite a bit of resistance to the water pressure. The pressure pump handles the filter nicely, the foot pump side has a very much reduced flow rate even with energetic pumping. Even at that I find it useful, allowing water to be pumped from the tank even if a pressurized side failure, or electrical fault occurs. It is very workable, the foot pump diaphragm does not lock - but expect flow to be restricted.

OK saw this post and it seams to answer this question.
"Water filter with manual pump faucet?"
The one solution was to add a SeaGull filter under preaure down stream.

Water filter on a Gusher Galley 3 gpm foot pump?
We have a foot pump (Gusher Galley) is 3 gpm foot pump at our sink. It pumps fresh water from the tank. We would like to put a water filter on it.
Has anyone had any experience with this?
Will it push water through a filter and if so will it require jumping up and down?
If it does push the water through without a lot more pumping what filter do you use?
