Measure the outside diameter (OD) of your existing pipe, not the inside bore. 50mm OD is standard for basin, bath, and shower waste branches. 75mm OD is used for some regional soil and vent configurations. 110mm OD is the most common size for soil stacks and underground drainage connections. If you are unsure, a vernier caliper gives the most accurate reading.

No. These caps are rated for non-pressurised gravity-fed waste and soil drainage systems only. They are not tested or rated for mains water pressure. For pressurised supply lines, use fittings specifically rated for the working pressure of your system.

For a permanent, watertight seal you should use a compatible PVC solvent cement. A dry push-fit may hold temporarily for pressure testing or positioning, but it is not a reliable long-term seal and can be dislodged by thermal expansion or vibration. Always follow the cement manufacturer's cure time before running water through the system.

Rigid PVC has good resistance to the dilute acids, alkalis, and surfactants found in typical household drain cleaners and waste water. However, prolonged exposure to concentrated solvents or high-strength industrial chemicals can degrade PVC. For standard domestic drainage use, chemical resistance is not a concern.

A solvent-welded joint is designed to be permanent. To remove the cap, cut the pipe just behind the socket using a pipe cutter or hacksaw, then fit a new coupling and cap on the shortened pipe end. If future access is anticipated, consider using a push-fit cap with a rubber seal instead of solvent welding.

Yes. The per-unit price decreases as pack quantity increases. For a typical new-build or renovation drainage rough-in involving multiple branch terminations, ordering a 10- or 20-piece pack reduces per-cap cost compared to buying individually. Select the quantity that matches your project scope to avoid unnecessary surplus.

PVC can be painted with a plastic-adhesion primer followed by a compatible acrylic or enamel topcoat. Standard wall paint without a primer will not bond reliably and will peel. Lightly scuff the surface with fine-grit sandpaper before priming to improve adhesion.
