My boilers pressure is automatically going up to 4 bars & the overflow pipe that leads to the outside is constantly dripping water. What do i need to do to get the dripping to stop & how ? Thankyou in advance for your help.
drop the water down throu radiator drain off.fire ch up ifc it goes over 3.drop the water down till no waters comming out.expansion is red and will have a tyre valve connection.normally looking down from the top off the boiler by the wall.take cap off pump up bike pump will do.put some fairy liquid on cap makeing sure it dosent bubble meaning air escape.fill boiler back to one and test.it should stay well under 3 bar.check outside copper pipe if its dripping you need to clean or change prv

Hi combi-doc 01214283335
I am not sure about what you mean by the pressure vessel as i am a complete novice when it comes to boilers. Could you explain exactly what i am looking for in simple terms please.

check filling loop to make sure its not open , if thats ok check pressure on pressure vessel if its below .5 bar or 10 psi repressurise with foot pump .

No i am pretty sure the filling loop is closed, maybe it is faulty ?
