and installed r/o units for freshwater. The principle is the same but the pressure is 800-900 instead of 45-100. Who knows, perhaps I evolve into a watermaker guru since I am halfway there via my freshwater experience.
Yes, I also have heard about the rumors on the performance of the Spectra. But on the other side there are also a lot of positive commentaries. So there is a lot of contradictions. I might admit that I would also be the proud owner of a Spectra after paying 6-8000$ for membership
card of the club even so there are more promises than delivered results.
However the energy recovery is a good technology and there are positive results. So for the sake of argument..... letīs say the marketing
managers always sell the promised land and the realities might be of another world.
I also watched the videos from Emerald steel and LaVagabond with eagle eyes. Further more I researched a little on the high pressure pumps and their maintanance. The vid from SV Catchin`Rays was also interesting to me because he repaired the WM with a standard off the shelve DC 12V electric motor
. When looking in depth
, most of the high pressure pumps wich are the most expensive mystery element of a WM puzzle, it seems they were designed for high pressure cleaning
and the only difference for other applications are the seals
and by the most the pistons to adapt to the requiered medium. All the other elements required are off shelf.
So maybe a pressure pump
from a pressure washer of Ebay in good shape and than buying
a complete maintanace kit for saltwater with all the seals
and this pump
is like new for peanuts.
The rest ????
The more I observe I ask myself what I need from my watermaker and what it should do and and how it can be done funtionally. Using basic instincts to understand the general principles the fog
cleared from my mind. This is not rocket science. Of course the manufactures put an attractive decoration on the pack to obstruct our boaters vision and not without success.....
We are all little boys that like to play with the toys))) Mmmm Yes
But comming back to basic instincts.... maybe I donīt need so many buttons and PC boards and a little rinsing the filter elements with fresh water by hand is no big deal considering the savings and the question of having and have not.
Then the desinfecting (piccling) of the filter elements after a longer period of time not using them might be an issue but to a certain point this time frame can be argued. To my understanding bacteria need oxygen to survive...
and anyhow as a permanent live aboard I will not have this problem.
Then a certain pressure has to be maintained to garanty a stable water quality.... and this water quality is messured and monitored
Hahaha, fresh water adventures))) I believe than You are at least professor. The rest is like opening a bottle of champaign and enter in the kingdom of the WM gurus.
I also have some fresh water experiences with a 4000 gallon installation
. I had some brackish water with an exciting mix. Close to the sea there were some salty element in the well, some spices from the neighbourīs inground black water tanks
mixed with a high octane cocktail from a big tomato green house and the worse... a lot of calcium and a constant change of the variables due to climate and relation of salt water
level in ground.
Correct me if I am wrong, that is a WM dream.
It cost me quiete some time to tune the beast.
Since I am not an expert yet, I hope You donīt mind if I remember our little chat,.... just in case I run into unexpected events
trying to open the bottle of champaign............
I think with my current budget
and my dreams I will give it some indepth thoughts to overcome my fears and resist the fancy temptation.
Hahaha, I donīt want to irritate the cruising kiddy.
However, if I can pick up a used unit that fits my needs for a cheap
price than I will reconsider my position.
The only thing I am afraid of is.... building a bigger unit might be cheaper and than starting the motor
could upset my inverter if I go AC.
If I go DC direct, in worse case a little capaciter modul might do the trick to keep the dimension under control.
Thxs for the inspiration....
Using basic instincts the world looks more friendly
SAYS... I LOVE DREAMING
I answered... and when the dreams come true itīs romantic
