I assume the original prob was the low pressure. Does this happen frequently or is it a new thing?

This has been happening for last 2-3 weeks and a restart (learnt from Microsoft!!) every 3-4 days have been keeping it going...

As Kev said, check the little pipe bit outside, also keep an eye on the pressure while the central heating is warming up,
 
airc it was on the other side of the back street in hartlepool

i took the pic to post on here as "how it should be done"

a few years ago

smug git :p
 
first call is to change the prv second is check the precharge in the expansion vessel

full description in the heating FAQ at the top of the forum

ang on just change the prv

mick has problems keeping up (joke) ;)
 
Judging from the Spielberg style intro to this topic, I think your limited understanding of sealed system and expansion vessels etc points to your needing a plumber experienced with central heating systems.
