Plumbing Material Checklist for Contractors: Every Stage, Nothing Forgotten

Quick answer: Order plumbing material by stage, not all at once and not item by item: (1) tank, pump line and riser; (2) first fix, the concealed supply lines; (3) drainage, stacks, traps and branches; (4) testing, end plugs and a pressure test before tiling; (5) second fix, valves, taps and sanitaryware. The tables below give what each stage needs and how many per bathroom, using the same counts as our 30x40 house estimate, with prices on 16 November 2026.

Copy any of these lists into the quote page and it is priced line by line in a couple of minutes, with a GST-ready PDF for the client.

Fill the system, pressurise it and hold it before anything is tiled: the method and times. Plugs are the cheapest line on the list and the one most often missing on test day.

Stage 5: second fix

Taps, angle valves, the health faucet, showers, WCs and basins. Prices for every model are in the Parryware tap, toilet and basin price lists, and one bathroom priced in full shows a typical set.

The items most often forgotten

• End plugs for the pressure test.
• A union beside the pump and beside the geyser, so either can be removed without cutting pipe.
• Solvent cement of the right type for each pipe: which cement for which pipe.
• Pipe clips for the stacks, which hold the building's drainage in line.
• Brass, not plastic, threads at hot points: geyser connections.
