You said "Mains pressure 3 bar, no PRV. "
How do you know the static Mains pressure of the OP's mains supply? how could you have possibly checked it? also All the range PM i have worked on have had a Pressure reducing valve fitted as part of the pack? bit of a job to remove them so how do you know it has been removed on this one?
you said "Plate heat exchanger, high resistance" "Scaled-up plate heat exchanger, huge resistance."
Against what?
"Static pressure on the downstream end of scaled-up, perforated, plate heat exchanger, 0.5, 0.3 bar, when the HW tap is running"
As Oll says this could happen, but the OP says the pressure drops to 0 and doesnt say that it goes back up? also says that the pressure doesnt equalise.
FYI I have no idea why its doing this, and unlike some on this here wonderful sight I cannot perfectly fault find over the net and need to "lock horns" with a boiler sometimes.
Hearsay; and that would have caused a gas explosion?
You didn't comment on the "few days". Let us hope that the facts are established at the inquest.
Have you ever been to a coroner's court?
There is no one there who is responsible for cross-examining the witnesses in order to established what happened. And if the appropriate questions aren't asked, then the jury, with the limited information available, may make a wrong decision about responsibility for the death(s).
I agree with you it is heresay now I think of it and i maybe should not have posted the reporters view in its entirity.
And yes I have been in coroners court many times and, as much as I hate to admit it, I should have know better you are right I should not have opiniunated so early or repeated what the reported stated
Dammit I hate it when I get it wrong goddamyou and I submit my apologies for that but I was not using it to have a pop at DIY'ers and nor would I use such a tragic death to make to score some cheap points for CORGI. And I still resent your comments stating that this was my sole aim.
PS and other than the over regulation and the big brother attitude of our government this IS a great country
