Build your own watermaker

After pricing on the market watermakers I decided to build my own. I built a fully automatin 45 GPH watermaker for under $2000.00. I documented the build and have the plans for sale on ebay.

Good for you Bob.

Water maker is not really a rocket science and parts are readily available. Most knowledge is open. Instead make a few bucks on eBay from a few poor sould, why don’t you share with other sailors. That is what this forum for. Who knows, one day the sailor that you help to build a water maker system may save your life on an open ocean?

OTOH, if have come up a proprietary membrane system to revolutionize the current approach, by all means market it your product. Make some serious bucks. My 2 cents.

Plans for a 45gph watermaker are available in the January 2003 issue of Good Old Boat. I agree with rockDAWG, it's not rocket science. It also lists parts manufacturers with their telephone and e/snail addresses. Given this site's affiliation with the magazine perhaps the article can be accessed thru Sailnet?

Could one buy a r/o watermaker intended for home use and boost the pressure up to 60 lbs with an auxiliary pump and use it on a boat?

What the heck is the membrane? Is that the long cylindrical thing than sits on top of all the other stuff? I disconnected my wm 3 years ago because of all the mx. I use rainwater from the bimini for most of my supply all run through seagull IV filters. But would like to connect it back up, but don't know how (I forgot....it happens when you get old).

Is there some site I can go to that will give me the schematics for setting one up?

ian-

If you know who made your watermaker, you should probably contact the manufacturer...they can help you with reconnecting it, and also supply you with the necessary pickling chemicals, as well as a new membrane.


Kavakava-

I kind of doubt it. Most homes don't have R/O watermakers, but water filtration systems. I can't think of a reason a home would have an R/O watermaker, unless they were on a desert coastline, with no access to fresh water.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I researched this some time ago with several Home R/O makers and this was what I found out.

Most of the Home R/O systems are intended for much lower Total Disolved Solids than that found in salt water. The membranes are also not intended for the pressure of a Salt Water R/O system.

Anyone care to update the topic ?

Seems as if the technology is moving on.
