the water at my marina is , well, nasty. high iron and sulphur well water. i can't use it untreated to wash my boat or fill my tank.
they have a 'portable' filter on a dolly, it weighs about 125 lbs, and is always in the farthest part of the marina (murphy's law and all)
so i decided to build my own portable system, figuring if the water was good coming out of the nozzle, i was better off.
i approached a number of places, hardware, building supply and dedicated water treatment system dealers for ideas, none were of any help. i wanted the system to be portable, but didn't want to have a bracket fabricated for the cost alone. after a few days of looking at the problem i came up w/ this system. i am using my horseshoe buoy bracket to hold the dual filters in place. the primary allows me to see sediment and change the filter as needed, and the secondary uses a charcoal filter to help make the water more palatable.when not in use, it stows nicely in my lazarette.
i also bleached the bejeezus out of my water tank and drained and filled several times.
the system cost less than $100 to put together. (w/ extra filters too).
as i see it, you can now use a simple under sink filter and be good to go.
