Task guide
When this may be needed
- The trap drips even after its seals were tightened.
- The trap has cracked, often after being over-tightened.
- The threads have worn so the bottom no longer seals.
- A smell rises from the sink because the trap no longer holds water.
- The trap doesn't line up with the waste pipe after a new basin.
What the team does
The technician removes the old trap and checks the waste above and the pipe connection below, so the new trap is the right size and height. The new trap is fitted with fresh seals, aligned with the waste pipe without strain, and hand-tightened so it can be opened for cleaning later. The sink or basin is filled and drained to test, and the trap is checked for leaks and its water seal.
