Back from work, just seen your post, I’m glad it worked for you, happy to help. :-)

Underneath the black cap is a schraeder valve for recharging the expansion vessel. The vessel should be charged to the same pressure that the water runs at. To check it, turn off the water,open all hot taps then place a gauge on the valve, if it’s lower than the water pressure ( or 3.5 bar if you don’t know the water pressure)pump it up to a similar pressure. If the pressure doesn’t rise when you pump it up then your vessel is f@cked. If you don’t understand what I’m saying then you need to call a plumber. Sorry, I’m off to work now so I won’t be able to answer any other questions.

For me the local trails becoming straight lines is much more of a STRAVA problem. :x

Whoever came up with that must have been a complete cugina. :D

The word ‘chillax’ – you may relax, you may chill but chillax boils my urine.

Picked up my new Orange P7 frame today, new long and slack geo and bolt through rear end. Just waiting on the oil to service/lower my Pikes then it’s all systems go! :P
