All,

I am going to wait a few more days to be able to get some more comments. I have been contacted by one group member who is an experienced ZOOM administrator and has a commercial account with ZOOM. This will benefit all of us.

Those interested please reply to this thread with their suggested topic(s), or any other suggestions. Once I have those suggestions, I will produce a "poll" of suggested date/times and topics.

When the above is completed, I plan to turn it over to the volunteer owner/administrator.

I am looking forward to this.

Bill

Hi Paul;

Was there a specific issue that you were dealing with that led Martin to give you that advice?

Mohammad,

I was told by Martin to run the water maker with the pressure at the beginning of the green zone. It also says this in the manual.

Hi;

When we first purchased Kokomo, I had detailed discussions with Martin, the head tech at Dessalator, about the environments that the water maker could be used and best practices. The following was my takeaway:

1. The water maker can be run safely in most waters. This includes harbors, marinas and even water that is not clear. I was told that the main detriment would be more frequent changes to the pre-filters.
2. The water maker can be, and should be, run in the high end of the green zone. This will lead to more water production, without any downsides.
3. Performing an auto fresh water flush after every usage is unnecessary and wastes about 20 liters of fresh water. As long as the water maker in run at least every week, a fresh water flush is unnecessary. We simply stop making water by shutting down the switch and then backing out the pressure valve.
4. Utilize the powder provided by Dessalator to prep the membranes for the winter season.

We have done the above for 5 seasons of about 5 months each. The pre-filters typically last a whole season. We never put any water in the tank other than from the water maker. The water quality is always below 250 PPM. When we purchased Kokomo, the water maker had only 60 hours on it. So, I’m fairly sure that our membranes are original from 2008 and therefore 12 years old. The water maker now has around 550 hours. I was told that after 500 hours, the quality will probably start to drop. Our usage has solely been in the Med.

Hi Colin,

Yes, I re-read that part and it is a little confusing how I wrote it. In marina, we do a fresh water flush aobut once a week. We do not run the water maker in that environment.

Thanks for the insight, I guess I need to be more fussy about where we run it. I thought the pre-filter would help a lot. I guess not.

With best regards,

Mark

Thanks, I had basically found the same things in researching this. However, something is amiss since we are using membranes at a rate much greater than others.

Hello Mark,

On Aquarius, we also have this problem with our 24V D60.  We continually see an increase in the ppm each year.  I have a few questions so we might flush this out...

1) Do you have a pre-pump that feeds your high pressure pump?
2) For those that have a pre-pump, do you see this problem?

I am starting to get the feeling that cavitation do to air in the system is causing the problem on Aquarius.  We only have a single sea water intake, stock Amel, and we do make water while motor sailing, and this could cause air to get into the water-maker system.  With the air in the system I am led to believe this is like a jack hammer on the membranes causing micro tears to form.  Overtime, the holes get bigger, and whaalaa 1000 ppm.

I don't have the pre-pump on Aquarius, but I am planing to add the pump when I install new membranes in about 6 months. 

Does anyone have any thoughts about this?

I need a little help with water maker usage and maintenance, please.

 

Cream Puff has a 24v D60 water-maker. My problem is we seem to be going through membranes at the rate of a pair a year. I have read where others have used the same set of membranes for years and still get drinkable water. This is not the case with us. We are in our 5th year of full time cruising and are now on our 6th set of membranes.

 

When I last change membranes in Colombia, this was about March 2019. Our current membranes are just over a year old. The PPMs are starting to creep up a bit now and we have gone from the 300 range to the 500 range. We notice a change in drinking quality over 600 PPMs. This is when we usually change the membranes.

 

We run the water-maker at least once a week when in a marina, flush it with the fresh water rinse. I have a double charcoal filter set up for the tank rinse. When on anchor it is run just about every day. I am careful to watch the pressure and water making float gauge. I normally set it at 55 liters per hour and this put the pressure in lower side of the green range.

 

Any ideas why our membranes are not lasting or why our PPMs creep up?

 

 

With best regards,

 

Mark
