Hi All.
can I ask a question. We have this boiler and I called the service to look at it as we have an issue with loosing pressure.
I am familiar with that one lever valve that allows me to refill the system.
can I ask though there are two adjustable black stopcocks.
One on the right seems to be just before the filling valve facing down and another in the middle facing front.
I need to buy new caps and they just spin on the valve.
But can I ask what these two are for and if they should be shut or open in normal operation?
thank you
