Yes, it is designed for standard waste plumbing which includes typical hot water discharge from sinks and basins.
This product is primarily designed for internal waste plumbing. Check local building codes if you intend to use it for external or underground applications.
This component is a standard plumbing bend; depending on the specific fitting type you purchase (compression vs. solvent weld), you may need separate seals or adhesive.
It is a 90-degree bend, specifically designed for a sharp right-angle turn in your pipework.
Yes, you can paint it using a plastic-adherent spray paint if you need to match the aesthetic of an exposed installation.
Check that the pipe is inserted fully to the stop and that your chosen sealing method (solvent weld or compression) has been applied according to manufacturer instructions.
Verify that your pipe is exactly 40mm in diameter; ensure there are no plastic burrs on the edge of the cut pipe that are obstructing the entry.
Ensure the bend is correctly supported by pipe clips to reduce vibration and that the interior is free of any obstruction or plastic flashing from the manufacturing process.
To install, ensure your pipe ends are clean and free of burrs. Measure twice before cutting your pipe to ensure the knuckle bend sits flush against the stops. If using a solvent weld fitting, apply the adhesive evenly around the pipe exterior before sliding it into the bend. If using a compression fitting, ensure the olive and nut are correctly seated to provide a pressure-tight seal. For maintenance, check the connection annually for signs of moisture or weeping. Avoid using harsh caustic drain cleaners directly through the bend if possible, as prolonged exposure to extremely high-temperature chemical reactions can degrade plastic fittings over many years.
