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 7 days maximum. 
 

1) 

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

3)  Close the seawater intake valve (sea cock) or switch the cleaning/storage valve to the closed position. 

4)  Open the fresh water flush valve on the active carbon filter. If the nylon tee with the flush/storage valve 

is supplied switch the valve to the flush position. 

 

Your vessel’s fresh water system pump should now turn on (larger 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. 

5)  Open the seawater intake valve (sea cock) and switch the cleaning/storage valve to the seawater 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  system 
pump). 

6)  Close the seawater intake valve. 

 

MEMBRANE STORAGE PROCEDURE 

 

If  you  intend  to  store  your  watermaker  for  more  than  7  days,  growth  of  microorganism  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. Preservative # 3 (Metabisulfite) for the 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. 

Infuse the solution with the cleaning storage hose while running the high pressure 
pump at lowest RPM.  Do not apply pressure.  There will be no flow at the fresh water outlet. 

 
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.
