Hi,
I wonder if anyone can help. I have bled my radiators then had to re pressurise the boiler as it was under 1 bar. After it got up to pressure I turned off all four valves but the 2 black ones (bottom ones as hard to see colour in photo) are leaking. Why does it leak when it didn't leak before and all i did was turn them on and off and what do i need to buy to fix it?
I've attached a photo to see if anyone can help.
Thanks
