Hi (new to forum) help needed
On CH mode the pressure increases to over 3 bar gradually in few minutes. PRV than activates discharging water as should whn reaching 3 bar, thn locks out with the pressure reading on (0).
After reading several post it pointed out 2 be EV needs charging. So i drained ater thru drain cock about 20n ltrs. pressurised the EV to up to 1 bar. Re filled heating system turn on the boiler on CH i thought this should cure it but did not still pressure is increasing.
Now i m in the understanding that EV needs changing. Possibly connect another about 12 ltr out side the boiler
Checked and fillin loop is not letting water in.
expert advice in this forum will be armly appreciated------Thanking all of you in advance
