My gas meter is fitted with a recessed meter box. The 22mm copper gas pipe passes through the cavity wall from the back of the meter box and is inside a plastic spigot. The spigot is sealed with some grey mastic stuff inside the meter box but there is no mastic on the inside wall where the pipe enters the property.
Should the entry hole inside the house be sealed with mastic too? Or left open like it is now.....
Gas fitter had to dash off all of a sudden and I'm just making sure this is right..
