Planning your kitchen plumbing: Avoiding costly mistakes in Singapore

Common mistakes include incorrect pipe sizing, improper drain slopes, not accounting for future appliance upgrades, neglecting water hammer arrestors, and failing to obtain necessary permits.

Keep the sink, dishwasher, and refrigerator relatively close to existing plumbing lines to minimize extensive pipe rerouting. Consider a kitchen island sink? Factor in additional plumbing costs.

Plumbing works typically require permits from the PUB (Public Utilities Board). Check with your contractor or PUB for specific requirements based on the scope of your renovation.

Install water hammer arrestors near fast-closing valves, such as those found on dishwashers and washing machines, to absorb the shock of sudden water pressure changes.

CPVC (Chlorinated Polyvinyl Chloride) and stainless steel pipes are generally recommended for their durability, resistance to corrosion, and ability to withstand high water temperatures common in Singapore.
