Turn off the boiler. Top up the pressure to ~1 bar if required.
Isolate the CH flow and return. Now remove and empty the condensate
trap[1], and replace. Leave for an hour or two and see if pressure has
dropped. Check the condensate trap again. If there is a leak in the
main HX, then there will be water in there (you may even see an
occasional drip from the trap mounting point.

Isolator valves don't usually completely isolate, they will still pass
some water.

It does not really matter - if you empty the trap and the boiler is not
running, it should stay empty.


Thanks, will try trap test this weekend

If you do the test and the trap does not refill, remember to refill it
manually, since its not good to run the boiler with an empty trap since
there is a slight risk it could allow combustion products back into the
room via the empty trap.

Finally got round to fixing mine:
