Choose the water supply or the drainage. For a supply, enter the number of fixtures and the lengths of cold and hot pipe; for a drain, the run, its slope and the bends and branches. PRAXAO gives the pipe with its waste, the bars to buy, the fittings, the clips, and for a supply the isolation valves and the hot-pipe insulation, or for a drain the total drop. Bar length, clip spacing, fittings per metre, slope and waste are starting values to replace with the plumber’s and the maker’s data. The tool counts lengths: it does not size pipes or check pressures.

Cold-water pipe, with waste: 44.00 m · Hot-water pipe, with waste: 27.50 m · Insulation sleeve for the hot pipe: 27.50 m · Isolation valves (one per fixture): 8 · Pipe bars to buy: 18 · Fittings: 39 · Clips: 82
No. Pipe diameters, flows, pressures and the slope a regulation requires are the work of a plumber or an engineer.
The total length is increased by the waste, divided by the length of a bar and rounded up to a whole bar.
It is the run multiplied by the slope: with 20 m at 1 %, the pipe falls by 0.20 m between its two ends.
Pipe lengths, waste, bars, fittings, clips and the drop of a drain: the method to order plumbing material, with examples.
Excavation, gravel, soil backfill, geotextile and pipes of a drainage trench or French drain, with the fall of the pipe.
Cable, conduit, boxes, circuits and breakers from a count of points, and the bars, brackets and covers of a cable tray run.
Capacity, excavation, concrete, formwork, steel and lining of a buried reinforced-concrete tank, basin or pool, from its inside size.
