Different examples of this type of job
This type of work often starts because something else changes: a radiator needs a better position, an internal waste pipe has failed, or an outside soil and waste line needs renewing. It can also mean creating a completely new run for a kitchen, bathroom, utility area or appliance. The aim is a sensible route, correct fall on waste pipework, a neat finish and a result that is easier to maintain later.

What to send on WhatsApp
Send your postcode, one wide photo showing the whole area and close-ups of the existing pipes, radiator position or waste route. If it is an outside drain or soil pipe, include the full wall run and where it connects. If something needs moving, add rough measurements and explain what is staying, what is going and where the new connection should be.
