[QUOTE="springcrocus, post: 287151, member: 935"] A new combi boiler has been fitted in a purpose-made cupboard in the upstairs bathroom to replace an ageing coal-fired back boiler. The existing gas supply runs from the meter box about two feet along the outside wall before going through the wall and under the kitchen floor to the gas cooker. The gas pipe is correctly bonded in 10mm G/Y about six inches above the floor. The heating engineer has chosen to replace the elbow where the gas enters the building with a tee, and extend the pipework along and then up the outside of the building before diving through the wall at first-floor level, thence to the boiler. Therefore, the gas enters the building at two separate points. The electric supply is TNC-S, the earthing conductor is 16mm, and bonding to the water is 10mm. All pipework is copper with soldered joints. An electrical supply is required to power the boiler and will be taken via a fused spur unit from the upstairs ring. Now the question. Does the new gas pipe in the bathroom also require bonding? (And why, or why not). [/QUOTE]
