Discuss Proper functionality of a pressure relief valve in the Plumbing Jobs | The Job-board area at PlumbersForums.net
It opens at its set pressure, but does not reseat until pressure has fallen a little below. Partly because after llfting there is more area of the mechanism exposed to fluid pressure. Water is released till that lower pressure is reached.Thanks for your reply DuncanM.
Does it release the water in a large 'dump' of water and then close. Or does it release the water slowly. Obviously, if operating correctly.
Thanks again
Not my favourite part of a boiler .
I have to ask, what is your favourite part of a boiler?
