    Thanks , the system is full but the pressure is a bit low. I thought if I re charged it the pressure would go up. Boiler is working fine at the moment .

    Because the pressure has dropped below 1 bar. I can't increase it with the filling loop . Which I have done before

    I didn't drain the system as I wasn't sure where the expansion vessel was. When I locate it I'm sure I will have no problems re pressurizing it. Thanks

    Hi First post, help needed. I need to recharge the expansion vessel on my boiler. I have opened it up and the only thing i can see that looks like it, is a small type pot sited by the pump. It does have a nibble on it but its very difficult to get a valve on it.
