Hi I have had an extension to my house built nearly finished but my kitchen dose not fit (nightmare) i thought of a soloution in moving the washing machine intergrated from next to the sink to approx 7 foot away on other side of the room there is space under the floor but not a lot can I plumb the wash /mach in from the sink plumbing and feed it 7 foot under thefloor or am i grasping at straws!
