Hi Guys tried to let some air out of a radiator but now have low pressure, tried opening the two black vavles but unable to up the pressure, cannot even hear water flowing. Any help much appreiated.
these are a constant pain in the butt! deffo fit an external loop (good advice carefree). if you still have warranty (which i believe you will have then call them out).

I have constant troubles with the internal filling loop on these boilers. Rather than buy another plastic tap (which will also fail eventually), try fitting an external filling loop, a more reliable and permanent solution.
