I have moved into a new build, with a oil fired 'grandee' condensing boiler, and direct fed megaflow system. The plumber has changed the PRV and tested the expansion tank which is ok. There is no visible signs of a leak, although the pipes are under the screed on the ground floor! I suppose the large drop in pressure indicates a leak on some sort? could it be a component failing? or a boiler problem?
Can anyone suggest some reasons this maybe happening? Or things i could check as the plumber is now on holiday for a week! As the next thing he has indicated he will try is cutting the main pipes and pressure testing upstairs then downstairs to try and find the leak!
Any ideas would be appreciated
