As Mark states above, location is a big deal. I always try to emphasize to people that watermakers are really an off shore piece of equipment
. I see more problem watermakers than most people ever will and at times wonder myself. But for every problem unit there are hundreds out there that tick along just fine. The biggest problem is usually owner lack of care and willingness to understand how to properly maintain and operate their unit. Watermakers do require a bit higher level of understanding and maintenance
than most boat
systems do. Just getting people to understand which watermaker they really need is an adventure in itself. Also if you are not already using one, I would suggest you have a 5-Micron filter pre-filter in line as well.
