I have tried every thing out there even attempted to build my own once.
fyi there is no such thing as an inexpensive WM. ps dont buy a used one either
I agree and disagree. I agree that for the vast majority of cruisers a commercial
unit is what they should be getting into. But there are those and many on this board that have shown the mechanical abilities to properly design, build, and maintain their own water
maker. The major problem with watermakers is a simple one, lack of owner care and the willingness to learn the basic care of their watermaker
. I've built two of my own and they more than satisfied my needs and palate. The first one gave me more than I could ever use 38gph. I learned quick that bigger is not always better. WMs need to be run often and I couldn't give away the extra water
I made. I built a 12V unit on a SW2521 membrane. I didn't care for the amps used to make the water though it worked fine and the 5-6gph was more than meeting my personal needs, but I wanted a little more to make life aboard a little more comfortable because I am not always by myself while sailing. Add two women
on board and my needs go up. I did a lot of research
on WM, visited several WM companies and tried to learn as much as I could. I learned, like many things in life, if you shop price
chances are you'll be disapointed in the long run. This is true about water makers for the vast majority of boaters. While bigger isn't always better a PUR 40 will leave most wanting more and questioning their purchase
. Some sailors are the ancestors of the Spartans to be sure. My experiances in repairing water makers is that most are not. Go into any second hand shops like Sailorman and you'll always find a few used Purs for sale
. Not because they didn't work
but mostly because the PO upgraded to a unit that better met their water demands. While speaking of second hand water makers I agree, if you don't have a lot of experiance with water makers or a have a very good friend you trust selling you theirs, stay away from them. Most will cost you near the price
of a new one to get them operational again and they will still be an old used one. Most are usually not worth more than the few spare parts
one could slavage from them. My advice
for the majority of boaters is a Water maker with a 40' membrane not two 21" membranes. One 21" membrane will cost you just as much as a 40" when it comes time to replace them So it doesn't make sense unless space is extremly critical. I've always found room for a 40" on even the smallest of boats. Watermakers are like vehicals, sure you can buy a moped, it'll get back and forth if that's all you want. You could buy an old Vega or Pinto and rebuild
it but you'd still have an old Vega or Pinto, not too many would take them off your hands and you'd never get back the money
you sunk into them. You could buy a nice new Corolla that will last. But if you want to travel from the east coast
to the west coast
and back a few times a new Caddy is what you'd be happier with and will do the job far more comfortably than the Johnny Cash "I built it one piece at a time" Station wagon.
