Hi just come across an installation low pressure and primary and secondary meter both have regulators installed.
Pretty sure it's not allowed unless it's a two stage system but this is low pressure.
I've explained that the primary meter must be regulated but after that the secondary should not really have another regulator because it can cause low pressure issues. Which is why I was there.
Can anyone confirm this because I'm sure it used to be in the IGEM book
