Looking for an explanation

it forces the contents back into the system and out of the tap until the pressure reduces to whatever the cold water intake pressure is?

That makes sense when the laws of physics are applied to the system.

So now you agree that there is an increase in pressure and flow from the higher water temp ?

Which begs the question whether or not Agile has been installing expansion vessels up until now??
Let's hope Agile takes on board the advice he has been given.

since when did the laws of physics apply to Agile ???

No Ian, it is not a law of physics but a law of digging a hole
Mr agile starts digging a hole and eventially disappears from the thread. He almost never admits he is wrong
Tony perhaps has not seen T&P valves with anti vacuum devices fitted on them

My guess being Agile has never fitted a cylinder let alone an unvented.
A charlatan of the highest order who gleans all his knowledge from others..fact.
