I'm just wondering in an 8 Ltr external expansion vessel would be up to the job if the original expansion vessel was isolated.
As per my other post, After a heating engineer installed the external expansion vessel and pump i get a huge gurgling noise every so often where the pressure bounces and the burner cuts out. The heating and water works fine for hours but every so often when the burner kicks in I get the problem
I had the engineer out today around 3 and he said that he had mistakenly left the bleed screw on the pump slightly open and that it was just air in the system. He got the air out of the system and left after explaining all to my wife.
It was fine until 9 o clock and when it fired up the problem came back. I turned the boiler off and then back on again but this time put my hand on the original EV which was the root of the gargling noise.
Can this be isolated from the system, at least to remove this from my list of possible causes as I'm doing my head in and ready to throttle him.
If I were to drain the system can I isolate this myself or is it a no-go
