Hi I have a Worchester bosch 34cdi 3 years old recently started to loss pressure associated with water running from the condensing pipe every 15 minuets I/2 a tea cup and i know this because it had a lift pump which i noticed was pumping all the time removed the pump placed a bucked under pipe and the bucket was full within 24 hours and i put a green food dye in the magclean and the water in the bucket is now same green so somehow the water from the radiators is leaving the system through the condensing pipe anyone any idea where the fault lies
