This article does a great job breaking down the technicalities of building a watermaker. As someone who's been living on a sailboat for years, I can attest to the essential nature of having a reliable source of clean water.

I would like to add a few practical insights from my experience. When choosing a pre-filter, consider one that's easy to clean and replace. It'll be the first line of defense against debris, and trust me, you don't want to be stuck doing a complicated changeover in an emergency situation.

Additionally, while the reverse osmosis membrane is indeed the heart of the system, don't underestimate the importance of the high-pressure pump. I learned the hard way that a poor-quality pump can compromise the entire system. Investing in a durable, high-quality pump has saved me from a few sticky situations out on the waves.

Also, maintenance is key to keep your watermaker functioning optimally. I make it a point to check my system regularly, especially before setting sail for a longer period. Regular checks also help spot minor issues before they escalate into serious problems.

Finally, I appreciate the emphasis on the independence this system can provide. Out on the water, you learn quickly that self-reliance isn't just a philosophy, it's a necessity. This watermaker design certainly embodies that principle.

I found this article to be a comprehensive guide on building a watermaker, a crucial piece of equipment for any sailor or survivalist. From my personal experience, I can vouch for the importance of water independence, especially when you're out at sea or in a survival situation.

I appreciate the detailed breakdown of the process, from pre-filtering to reverse osmosis. My own system aboard my 40-foot sailboat operates on similar principles, ensuring I have clean water whenever I set sail. However, I'd like to add that maintaining the system is as important as setting it up. Regular cleaning and occasional replacement of the filters, especially the reverse osmosis membrane, is vital to keep the system running efficiently.

For those considering the portability aspect, I've found that having a dedicated setup on my sailboat and a portable one for land use provides a good balance. The portable one is especially useful during emergencies when I have to leave my boat behind.

Lastly, I recommend sourcing durable parts, even if they come at a higher cost. Saltwater can be quite harsh on the components, and having robust parts can increase the lifespan of your watermaker. It's like navigating through a storm - you need a sturdy vessel to come out on the other side.

I'll be sharing this article with my fellow preppers and sailing enthusiasts. It's a valuable resource for anyone looking to enhance their survival skills or increase their self-sufficient lifestyle. Keep the valuable information coming!
