Hi, this is my first post.. hoping it's an easy one that someone can help me with.
I've got a standard system (not a Combi.. just a Bosch gas boiler and a hot water tank).
Anyway.. everytime the CH valve turns off, I get a REALLY LOUD clunking noise from the system.
I've done some reading around and one forum suggested that the Diverter Valve may have been installed "the wrong way round" - so i checked... and it has been !
So, all I need to do is disconnect the brass valve, turn it round and re-install - happy days.
Here's my question... what do i need to do in-order for loads of water (under pressure) not to shoot-out when I remove the diverter valve ?
Is it just a case of taking the CH pressure down to zero by removing 'some' water from one of the downstairs radiators until the pressure dial goes to "zero" ?
And then re-fill the system / bleed the radiators after I've spun the valve round ?
