Sorry I missed the livestream.
This format really suits the content and Ryan’s explanation is very clear, natural, and incisive.
Great explanation of how the watermaker works. Very informative!
The presentation is awesome!
Would be much better to do the presentation, then do a Q&A afterwards. Maybe fo the presentation as a separate video.
F***ing beggers! Soooo sad.
Your AC vs DC efficiency argument really depends. You missed the efficiency loss in DC over cables.
A good inverter loses %6 efficiency, but your 24V DC power cables are probably losing twice that, if your water maker is 10 feet from battery, and four times that at 20 feet… or you are running really heavy cables. At 12 volts it’s even worse.
Rough figures, you can calculate the loss for your situation and if the water maker us right next to the batteries then very thick welding cables will result in very little loss. The voltage drops you’re talking about are reflecting efficiency loss.
If you’re going to have an inverter anyway, then the location flexibility makes AC worth it for most.
There seems to be an almost religious belief on forums that inverters are super inefficient. I think this comes from people who don’t understand what they are. They think cables are perfectly efficient because they aren’t doing any conversions. But they then use under sized cables, resulting in a worse situation.
You have to do the math and if efficiency is your goal, size the cables up a lit or make them very short— ideally both.
I can't get to the video live, but wanted to mention how good they are even watching after. Content was well organized and you two make a great team presenting it. For me it is mostly a curiosity (old ex-sailor) but fun to watch and learn. Thanks.
Interestingly, John Kretschmer has been using a Rainman for a few years and has been happy with it… We've seen it in action on two passages and think it's a pretty slick solution if you don't want to go through the hassle of installing a system. It's a little spendy, but he's on the water for several passages a year and is still using the first one he bought in 2016.
Hi Ryan & Sophie, I watched a video where a guy used a high preasure cleaner to run his water maker. Is that something you have checked out?
Hi Guys. I enjoyed your vid a lot, liked the diagram also. How did you do the bypass for the feed pump? Does the bypass go overbord? How is that designed? I will build my WM next month. Thanks for the info
How about pickling and un-pickling (de-pickling?)? What is involved with that?
Great tech talk. I learnt a lot and will follow your decisions when the time comes.
Cost wise I am very much in favor of the DIY alternative. Could you advice type and manufacturer of the main components you used and internet source if possible. Thanks
What HP of electric motor is needed ( assume soft start motor). Thanks.
The high pressure pumps seem to have ceramic pistons. Some SS other not. Is any Baldor type motor best?
Can you arrange for a printed parts list?
Good job guys. Great video. Definitely looking forward to more in the future.
Thanks for a great video, Rain man also make kitform units that can be installed spread out to fit
As usual Ryan did a great job explaining something that is technical and complicated and made it simple! Great job!
HI Sophie, This could help in your MAC repair. https://www.rossmanngroup.com/https://www.youtube.com/user/rossmanngroup
Hi guys I have some good news for you I bought my water maker from the same guy that you did Mike / in Fort Lauderdale and he was great to work with as you said I was very fortunate I followed your directions about using 10 wraps of Teflon tapes on all the joints where it was needed and luckily put the whole thing together no leaks no leaks not even a towel to soak up anything work the first time right out of the box so to speak we must have got very lucky but watching all these videos on YouTube certainly helped with an ounce of prevention and 2 lb of planning and a lot of homework from your website there were no tears and no leaks we just finished last night at 8 p.m. and we were joyed when at work the very first time
There are a lot of things that can effect the production of a RO unit. There is the temperature, TDS, Salinity, and hardness just to name a few.
This is great format!
Really good information on RO! Thanks I enjoyed it. Can you help me understand something? I have noted small and medium size units using the same membrane. Dow says it can except 6 gallons /min for a (SW30-2540) daily production @700 gal/day (29.1 hr). So the choice of a unit comes down to max output of a motor/pump combination (that does not exceed each parts Max (rpm or psi) and fits your power consumption requirements?
