We live on the 2nd floor of a Victorian semi-detached and the kitchen is on the corner of the house (rather than against the party wall). I've been thinking of getting a dishwasher, but to fit it into our tiny kitchen we'd have to move the waste pipe in some way. Is it difficult to move the waste pipe without scaffolding on? We have scaffolding for the time being because exterior works but it will soon be coming down. Should I try to get a plumber in ASAP?
