When we were getting familiar with Kokomo, I had discussed when the back flush was necessary with Martin at Dessalator.  He stated that it is unnecessary to back flush after making water, if you intend to make more water withing the next 7 days. He mentioned that it is a waste of 25 liters of water. When we are on board, about 5-6 months every year, we almost never back flush since we only fill the tank with dessalator water, and therefore never go beyond the 7 days.

 

Our original membranes are still functioning fine after 12 years and almost 600 hours of water maker run time. The water made is usually below 250 PPM.

 

Happy Sailing;

Dear Amelians,

today I had a wierd situation with my duo D 100.

After turning it off, it did the fresh water rinse like usual, but did not stop.

I checked for a leak (in the entire boat) but there is no leak and no open tap.

I closed the fresh water valve for the water maker, the rinsing stops.

I opened the valve, then the fresh water pump starts again (with rinsing).

During the process of making water there is no problem, the fresh water pump is not running.

Thus now I have to close the valve every time after using the water maker.

That is possible, but not like it should be.

 

Btw: If I open the fresh water valve for the water maker again (at least) 1 hour later, the pressure is (mostly) stable, no pump is running.

What could be the reason/ problem?
The solenoid (parallel to the filter)?

Thx a lot for your help.
