Measure the outer diameter (OD) of your existing pipe with calipers or a tape measure, then refer to the standard PVC pipe OD-to-nominal-size chart for your region. The fitting's listed inner diameter (ID) should match the pipe's nominal size — for example, a 32 mm ID fitting accepts standard DN32 PVC pipe. When in doubt, bring a short pipe offcut to compare before ordering.

These fittings are designed for solvent-weld PVC pipe systems. Suitability for pressurised supply lines depends on the specific pipe schedule and local plumbing code. For drainage and gravity-fed irrigation applications they are widely used. If you are installing on a pressurised supply line, confirm the pressure rating of both the fitting and the pipe with a qualified plumber before proceeding.

Yes. Rigid PVC is inherently resistant to rust, scale, and a broad range of household and agricultural chemicals including fertiliser solutions, mild acids, and chlorinated water. It will not corrode in damp soil or concrete encasement, making it suitable for buried drainage and irrigation runs. Avoid prolonged contact with strong solvents (other than approved PVC cement) or concentrated oxidising acids.

You will need: a pipe cutter or fine-tooth saw, deburring tool or sandpaper, PVC primer (where required by local code), PVC solvent cement rated for your pipe schedule, and a natural-bristle applicator brush. Clean both the pipe end and fitting socket with a dry cloth before applying primer and cement. Assemble with a quarter-turn twist and hold for 30 seconds. Allow at least 15–30 minutes before handling and 24 hours before pressurising.

Common household drain sizes are: 32 mm for basin and bath waste outlets, 40 mm for kitchen sink and shower waste, 50 mm for soil vent branch connections, and 110 mm for main soil stacks and underground drainage. Always verify against your existing pipework before ordering.

Grey PVC is suitable for direct burial in soil and for encasement in concrete, provided the pipe and fitting are rated for the application. Ensure the trench is free of sharp stones that could stress the fitting wall, and use a sand bedding layer for larger diameters (90 mm and above). Check local building regulations for minimum cover depth requirements.

For a single repair or one-off connection, the 1-piece option keeps cost low. For a planned installation with multiple direction changes — such as an irrigation manifold or a drainage run with several bends — ordering a 5- or 10-pack typically reduces the per-unit cost and ensures you have spares on hand. Check the price-per-piece across pack sizes on this page to find the best value for your project volume.
