Hi Just returned from Holiday and found that our son had not Hot Water or heating for 2 weeks. pressure was really low. I opened the filling loop to increase the pressure up to 1bar. Like an iidiot i opened it to much and the valve shot out and flooded the place. I sorted this out but since then the pressure has been at 2.6bar appx. and water dripping out of the pipe outside. I have tried bleeding all the radiators but no good. I then tried bleeding some water from a radiator downstairs. This reduces the pressure to where i want it but within an hour it is back up again. I have done this 3 times now with the same results. Any Ideas please would be much appreciated. [/b]
