Hi, my combi-boiler has started losing water pressure on the CH. I have just done some alterations with some rads but the pressure does not keep up. There appears to be no leaks any where, including the news ones & old connections. The PRV is not leaking or any visible leaks from the boiler itself.
Are there any components inside the boiler that could cause the pressure to fall & is their a way to check them.
Thanks in advance,
Andy
