Evening All, I am after some advice please. I live in a Taylor Wimpey home built in 2016. I want to change the confit of my kitchen which was part of standard build with the house. We are looking at opening it up with Bifold doors and an island in the middle of the kitchen. Under the sink by the back window the main stop cock comes into the house. How and what’s the best approach to relocating that into the island as this area will be replaced by bifold doors. My dad believes it’s a concrete slab with screed but I am confused to what’s the best approach to reclaiming that mains into the island - can anyone help please ?  Would this pipe of come straight from the front under the house or would they have gone round. Can anyone recommend what’s the best approach with this
