Extended Product Information

FAQs

Does this trap fit all standard basins?

It fits most standard basins that utilize a 1.25-inch waste connection.

Can I use this with copper pipes?

Yes, the multifit outlet is specifically designed to be compatible with plastic, copper, and lead pipes.

What is the P, S, or Q configuration?

These refer to the shape of the pipe run from the wall or floor. The adjustable swivel allows you to set the trap to exit in whichever direction your plumbing requires.

Is the stainless steel flange included?

Yes, the kit includes a 60mm polished stainless steel waste flange and center pin.

How often should I clean the trap?

It is recommended to clean the trap whenever you notice slow drainage or periodically during routine bathroom maintenance.

Troubleshooting

Water leaking at the swivel joint

Ensure the internal O-ring is seated correctly and that the compression nut is tightened evenly.

Slow drainage from the basin

Unscrew the bottom trap section to remove hair or soap scum buildup that may be obstructing the flow.

Unpleasant smells in the bathroom

Check that the trap is filled with water; if it has been dry for a long period, run the faucet for a few seconds.

Pros and Cons

Pros

  • High-quality 75mm water seal prevents odors effectively
  • Versatile multifit connection suits multiple pipe materials
  • Flexible design supports P, S, or Q trap configurations
  • Includes all necessary components for a complete installation

Cons

  • Requires proper alignment to prevent leaks at swivel joints
  • Limited to 1.25-inch basin connections
  • Requires basic plumbing knowledge to ensure airtight seals

Setup, Compatibility & Care

To install, ensure the basin is clean and the waste hole is free of debris. Use the included center pin to secure the stainless steel flange to the basin drain. Apply the provided dry jointing washers on both sides of the basin to prevent leaks. When connecting to your waste pipe, slide the multifit nut over the pipe, insert the pipe into the outlet, and tighten firmly by hand. Avoid over-tightening with tools, as this can crack the plastic components. Periodically check the trap for blockages by unscrewing the bottom sump to clear debris, ensuring the water seal remains intact.
