I am after some advice about the vokera linea 24 as my mother in law has one fitted and it is rapidly losing pressure when the system is off but is fine when the system is on. It takes around 15/20 mins to drop from 1.5 bar to zero. I have checked the rads and pipe work for leaks and there all fine. I cannot see an overflow pipe anywhere that often drips with this problem according to previous post's. There is however a red topped valve near the diverter valve is this the PRV as i under stand these can be faulty ? Failling that would the pressure vessel need recharging ?
Any help or advice woud be much appriciated.
