What to check when buying plumbing materials for your home

Why this matters

A mismatched fitting or a low-grade valve can leak within months, damage walls and cost more to fix than the part itself. Choosing correctly at the counter saves repeated trips and repair work.

Main things to check

• Material type — PPR, CPVC or PVC for different water and temperature needs
• Size and diameter must match your existing line exactly
• Thread type and joint style so fittings connect correctly
• Intended use — drinking water supply, drainage or hot water
• Local availability of matching spare parts for later repairs

Things to consider before you buy

• Measure the existing pipe and fitting size instead of guessing
• Buy a few spare joints and connectors for the same project
• For hot water lines, confirm the fitting is rated for temperature
• Keep the packaging label so you can buy the same type again

Common mistakes

• Mixing brands and sizes on the same line, causing leaks
• Using drainage pipe for pressurised water supply
• Buying by eye instead of measuring the actual size
• Ignoring whether the part is for hot or cold water

Practical checklist

• Note the pipe diameter and fitting type you need
• Confirm whether it is for supply, drainage or hot water
• Match the thread and joint style to your existing line
• Pick up a few spare joints and connectors
• Keep the label for future reordering
