 It  might  be  leaking  or  your  main  knob  is  not  open.  There  are  definitely  a  lot  of  adjustments  that  one  has  to  make  is  what  i  learnt  from  my  setup.  Once  they  are  right  all  seems  to  go  fine.

 Use  soap  soultion  at  the  joints  and  if  it  bubbles  up  there  is  a  leak  at  the  joint.  Hope  this  helps.

 This  is  the  right  way  to  check  for  leaks.   Thumb Up   
 Plain  water  will  not  help  unless  you  can  dip  the  whole  part  underwater.  Not  practical.
 But  if   there  is  no  Co2  in  your  cylinder  you  cannot  do  anything.

 Maintain  the  pressure  to  around  2  kg/cm2  maximum.  4  is  way  too  high.

 The  answer  is  already  given  ....  soap  water  solution.  But  as  Trevor  pinted  out  without  any  Co2  left  in  the  cylinder  it  wont  work,  you  will  have  to  get  it  filled  again  and  then  do  it.  
 
 Just  one  pointer,  when  you  get  it  refilled,  get  them  to  check  if  there  is  any  leak  in  the  Cylinder  Valve  itself,  there  is  a  rubber  bush  inside  the  Valve  on  the  cylinder,  if  this  bush  becomes  weak  or  is  faulty  then  you  will  have  CO2  leak  as  well.

 this  is  what  i  am  having  with  me.r  u  talking  about  the  leakage  from  the  neck  of  cylinder  ?will  get  my  cylinder  refilled  tomorrow.refilling  is  not  a  costly  affair  but  we  have  to  go  somewhat  30  kms  from  town  to  get  it  filled  and  this  is  very  painful.  Wall Bang

 i  have  circled  the  joint  that  needs  to  be  opened,  when  you  open  it  the  entire  tap  unit  comes  out  and  at  the  end  of  this  unit  there  will  be  a  rubber  washer,  if  this  washer  is  damaged  then  there  will  be  a  major  CO2  leak.
 
 Note:  Please  get  this  done  by  the  professionals  itself.  Please  don  not  attempt  this  yourself.

 The  other  important  point  to  take  note  is  that  the  valve  on  top  of  the  cylinder  should  be  completely  opened  .  If  its   half  opened  then  there  can  be  a  leak  too  as  the  cylinders  have  been  used  ad  reused  many  a  times  before  you  get  it.
