combi boiler problem

[knocker1]

hi hope someone can help! i'v got a ravenheat condensing fan boiler CSI 85
the prolem is i'v lost all pressure,so filled back up to 1.5 bar then went and bled all the rads! again back down to 0, so filled back up again went an checked all rads and valves for leeks.Found none wot i have noticed is the boiler o/flow as a constant trickle o warm water
so am now filling the boiler with the loop at the same rate its coming out of the o/flow wots wrong with it

PRV is passing probably needs replacing

What I think Kev was trying to get at is that replacing the PRV will repair the problem of water passing but you need to consider why the PRV has opened in the first instance.

It may just be one of those things and replacing the PRV will be all you need to do but it is best to keep an eye in the system for a few days as you could have a problem elsewhere eg with the ex vessel etc etc.
