Some of the reasons why this may be happening and also how to correct the fault are set out in the table below:

Possible Causes	Solution
the bar tap is set incorrectly	adjust the tap control that regulates the flow rate
the gas pressure too low	the most likely cause is that you have run out of gas check the gas cylinder pressure gauge if the cylinder is empty, change it for a full one of the same type if the cylinder is not empty, there may be a fault with the gas pressure setting - contact your brewery
the keg is empty	check the keg and replace it if it is empty check that the cellar buoy is reset correctly
there is a kink in the beer line	check the line and remove any kinks
There has been a change in demand due to increased beer sales	identify which gas is needed and contact BOC Sureserve to arrange a delivery
