It's a Greenstar 30Si combi, about ten years old. Few weeks ago, it needed the pressure relief valve replaced, as it had a steady drip. Engineer replaced the valve for me, steady reliable bloke, known him for years, I was in the room while he did the job.
However it's still dripping – I've stuck a bucket under it, and measured a bit over two litres in 24 hours (and no, it wasn't raining!). But the boiler's not losing pressure – needle still well in the green – so where's this water coming from? Explanation much appreciated.
