The plastic pipe is used inside the flat in between Gas meter and Stove instead of Copper pipe.
It is mentioned in CP-MGLLTD-S message dt.01.09.2026(4.42PM) that Copper pipe up to 5.00 mt. & 1.5 mt. long rubber hose pipe are free of cost.
Then why plastic pipe is fixed instead of Copper pipes.
Request to replace the plastic pipe with Copper pipe
