FRESH WATER FLUSH PROCEDURE 

 

Caution:    The  fresh  water  pressure  should  not  exceed  the  range  of  the  low  pressure  gauge/s.    The 
installation of a pressure reducer may be necessary. 
 
If  you  don’t  use  your  watermaker  for  the  next  three  days,  you  will  need  to  flush  your  system  with  fresh 
water or infuse a biocide solution.   
The fresh water flush prepares your watermaker for a shut down period of seven days maximum. 
 

1)  Open the pressure control valve all the way (two full rounds after the spring releases) counter clock 

wise.   

2)  Close the sea water intake valve or switch the cleaning/storage valve to the closed position. 

3)  Open the fresh water flush valve. Your vessel’s fresh water system pump should now turn on (larger 

fresh water pumps will cycle on and off). For the next flush procedure, test how long it takes until 
the brine at the outlet becomes fresh. Allow fresh water to flow until all salt water is flushed out of 
the RO System. 

4)  Open  the  seawater  intake  valve  and  switch  the  cleaning/storage  valve  to  the  sea  water  position.  

Allow fresh water to flow until all salt water is flushed out of the pre-filter(s), boost pump and the 
sea  strainer  (approximately  30  seconds,  depending  on  the  flow  rate  of  your  vessel’s  fresh  water 
pump). 

5)  Close the sea-water intake valve. 

 

MEMBRANE STORAGE PROCEDURE 

 

If you intend to store your watermaker for more than seven days, growth of micro-organism will degrade the 
RO membrane(s) performance.   
 
The RO membrane(s) should be flushed with a biocide solution.  This will preserve the membrane for long-
term storage of up to one year. 
 

1.  If you have installed the optional fresh water flush system, back flush the pre-filter(s), the boost 

pump  and  the  sea  strainer  with  fresh  water  and  remove  the  pre-filter  cartridge(s).    Close  the 
seawater intake valve (sea cock). 

 
2.  In a clean plastic container, mix 2.5 gallons / 10 litres of un-chlorinated fresh water with 100 

grams (1/3 container) of Echo Tec. membrane preservative # 3 (Metabisulfite) for models 200-
900. 
Mix 4 gallons / 15 litres of water with 150 grams (1/2 container) of preservative for the models 
1200 and 1500. 

3.  Switch  the  three-way  valve  to  the  cleaning/storage  position.    Switch  the  diverter  valve  to  the 

sample position. 

4.  Open the pressure control valve all the way counter clockwise (two full rounds after the spring 

releases). 

5.  Use  a  funnel  (avoiding  air  to  enter  the  system)  to  pour  the  solution  into  the  cleaning/storage 

hose or lead the hose into the elevated plastic container while running the high-pressure pump. 
When the solution has been infused, switch off the watermaker. 

Under best conditions your watermaker is now prepared for a shut down period of ten months. 
 
Discard the product water for at least thirty minutes of initial operation, after storage before drinking or before 
use in food preparations.
