Plan before chasing
Confirm the final positions and specifications of toilets, basins, baths, showers, mixers and wastes before pipe routes are changed. Late layout changes are expensive once waterproofing and tiling have started.
Coordinate the trades
Plumbing penetrations, falls, traps and valves affect waterproofing, screeds, ceilings and cabinetry. The programme should define when testing happens before finishes cover the work.
Test before closing
New or altered pipework should be checked before access is closed and before sensitive finishes are installed. Photographing concealed routes can also be useful for future maintenance.
