Isn't atmospheric pressure like a 1000mbar? Probably need to multiply the numbers by 100.
As i said, my memory is awful, but i think that those were the figures above atmospheric pressure. i.e. if the pressure that day was 1011mbar, then the initial pressure in the pipe would be 1036mbar. Or perhaps the meter was reading 1025mbar to start with...
I do know that the pressure in the gas pipes is very very low, because he also told me that since i had soldered all my water pipes and they were ok, then my gas pipes would certainly be ok, because you can put flux on the fittings, push them together, and then not solder them, and the pressure of the gas will not be high enough to push the fitting apart!
