Today was our new pipe to the house day.
No gas from 11am until an hour ago. It was getting a bit chilly towards the end. Been fascinating seeing how they work. The gas main is a 6" bore cast iron pipe this side of the road. The other side is 8".
Yesterday they fed what looks to be a 4" poly pipe through it without interrupting our supply. no idea how.
Today from 8am they dug access holes where (they said) 29 house supplies meet the main. Once they had all the holes just before 11 the gas went off. they then had 2 or 3 teams working down the holes and in peoples houses.
In ours they first removed the gas meter then hack sawed through our pipe in the hole in the pavement. Once the small pipe was cut they smashed the cast iron main pipe with a steel bar exposing the yellow plastic pipe inside.
With the main out of the way they then tried to push a liner pipe all the way to the meter position.... but it wouldn't turn the elbow corners. So they dug up our front drive near the house and cut a foot of pipe out. They then blew a rope down the pipe with compressed air from the meter position and connected it to a corrugated extra flexible pipe. Push and pull then got that pipe through.
Seems most houses this side were difficult to get the liner pipe through and they are still working outside on other houses now.
nice to have the heating back on
