Re: Suggestions for Watermaker

Any 3GPM presure washer pump with ceramic plungers will work , engine driven. Under $300 . A friend , in the watermaker business for many years , told me they are far more solidly built than the ones they make for watermakers. The mebrane housing can be welded up from 2 1/2 inch sch 40 stainless pipe from the scrapyard, $2 a pound. You do have to buy the mebrane and one pre filtre, as well as some hydraulic hoses and fittings. Watch them put the ends on the hydraulic hoses . Make sure they don't put a gob of grease on them, as some hydraulic shops like to do. That will kill your membrane.
$20 plus postage for my book will be one of the cheapest components. .
