Standards and rules to check
Water pipes and fittings must meet PUB's standards and requirements, which cover materials such as polypropylene (PP) pipes. Licensed plumbers must also follow the Singapore Standard CP 48 for water services, and a licensed plumber who installs non-complying fittings can be penalised under the demerit system. Ask the seller to confirm in writing that the fittings meet PUB requirements. Warranties on pipes and fittings in HDB flats and developer homes are typically void when unlicensed personnel do the work, so check who will install them before you buy.
Season and weather
Singapore has no winter, and the climate is hot all year with a wet season and a dry season. Pipe work is not tied to a cold-weather period, so you can order at most times of the year. Heavy rain can soak the site and hold up trenching or outdoor fixing, so plan digging for the drier months where you can.
How pipes are sized and sold here
Sizes are metric: diameters are given in millimetres (12, 32 or 50 mm) and lengths in centimetres or metres. Some listings advertise free shipping, so compare the total delivered to your town, whether that is Singapore, Tampines, Jurong West, Woodlands or Ang Mo Kio. Most listings are per piece but some are per pack, so check the unit before you add up the quantity.
