*Ideal  values  denote  typical/acceptable  levels  for  system  water  correctly  dosed  with  good  quality  proprietary  Inhibitor    Interpretation  of  the  Results    

pH  is  at  limit  of  acceptable  range.    Conductivity  would  indicate  presence  of  chemicals  in  system  water.  Hardness  is  low  and  would  indicate  that  limescale  precipitation  has  occurred  Alkalinity  would  indicate  presence  of  chemicals  in  system  water.  Net  chloride  level  is  excessive  and  would  indicate  that  system  has  not  been  thoroughly  cleansed  &  flushed.    Chloride  level  would  be  expected  to  increase  risk  of  pitting  corrosion.    (Additional  chloride  may  derive  from  residual  flux  or  cleanser  in  system).    Trace  of  boron  would  indicate  that  system  was  dosed  with  inhibitor  but  concentration  is  now  very  low.    

CONCLUSIONS      

1. Chloride  level  would  be  expected  to  result  in  increased  risk  of  pitting  corrosion.  2. Trace  of  inhibitor  is  present  but  concentration  is  very  low.    

RECOMMENDATIONS    

1. Drain  and  flush  system  with  proprietary  cleanser  in  accordance  with  BS  7593:2006.  and  add  appropriate  proprietary  inhibitor  at  final  fill.
