There is a great thread on this somewhere, adn I do believe the comments on this are outdated.

I have absolutely no problem with making your own WM - if you have a large generator or can put it on your main. Not a great idea otherwise. You may also have some difficulty with getting a wm small enough on your own as most of the home models (IIRC) are 20gph minimum. Nice for a guy like me with a family, not a furry wombat.

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.

Watermakers are easy to make but home-made ones are not necessarily that inexpensive. The cost is in the membrane and also a decent stainless high-pressure pump.

But the mechanics are simple and if you have a friendly engineer who can spin up some of the bits for you, a decent watermaker can be had for a lot less money than the commercially available ones.

There are, I think, several websites that will provide the how-to basics

TDW,
have a look at Citor. They are in WA. There will be a sales rep in NSW. I have a 90L/hr model - uses a davey pump and filters you can buy anywhere.

Gooday Oma, how are you.
We are flying over soon to WGTN soon. Hope the weather is summery.

Why would you want to do that?? Come to Auckland instead.

BTW I'm good thanks, how are you? And seriously if you are ever heading to Auckland give me a heads-up.

Well, I personally have seen that there is a price difference - but it is not massive unless comparing against a Spectra or other 12v, high end model. I have always felt the big positives are that you can make a LOT of water quickly, and if it breaks, YOU know how to fix it. Go look at a Spectra to get a feel for what I am saying.

The negatives are that it is labor intensive, it is much larger than the typical commercially available units, and it may make too much water for you. The rule of thumb I have always considered is that you want to run your watermaker everyday or every other day to keep them membrand nice. WHen you start pushing off to a week+ between runs, you may have a problem with junk building up on the membrane and a premature death.

Note: Dad has a watermaker, not me. His is the SPectra. Nice unit, totally automated, and if that appeals to you and money is not an object, it is a good choice and good product. It is also the most efficient. I am either going to purchase a unit that is of the homemade variety (go here: Aquamarine, Inc - Home as I have seen on eof their products and that is all they have done) or I am going to make my own. I can use the large water cap and I personally want something I can repair and diagnose on my own. This does not appeal to everyone though.

PS You need a generator (unless you are really creative and can run it off your main and have the power to do so). I am not sure a 'Honda' would push it. If you do not have one, take it off your list.

I am just wondering how often you have to replace the filters on a watermaker.

That depends on how much you use it and how clean the water is where you use it.
