How do I get the pressure down, I accidentially put it up too high? ?

if you know how to operate the relief valve thats ur best bet, if not, make sure ur rads are cold ie heating off then get a pan under one of the nuts to the side of ur rad loosen nut with spanner catch water in pan and retighten probably best if you turn boiler of completely providing you know how to restart it

your filling loop is probably stuck on !disconnect to see.if you cannot disconnect it turn the cold main off and then drain some water out of a rad the pressure will go down.
