How to Clear a Clogged Floor Trap

  1. 1Put on rubber gloves and lift off the floor trap cover. Most lift straight up or unscrew.
  2. 2Pull out hair and soap build-up with your fingers or a plastic drain hook. Most blockages are within reach of the top of the trap.
  3. 3Pour a kettle of hot water, just off the boil, down the drain to melt soap scum.
  4. 4For a slow drain, use half a cup of baking soda followed by a cup of vinegar, wait 15 minutes, and flush with hot water.
  5. 5Fit a hair catcher over the floor trap to stop it happening again.

Stop and call a plumber if

  • Water comes up through the floor trap when the toilet is flushed

Clogged Bathroom Drain FAQs

StringsSG clears clogged drainage pipes from $94.76 at a fixed price, shown before you confirm the booking.
Water rising from the floor trap means the drain below it is blocked, so water from the shower or basin has nowhere to go. If it rises when you flush the toilet, the blockage is further down the shared pipe and needs a plumber.
Fit a hair catcher over the floor trap, clear it after each wash, and lift the trap cover to clean out build-up every few weeks.
A smelly drain is often a dry floor trap. The trap holds water that blocks sewer smells, and it dries out when the drain is not used. Pour a jug of water in. If the smell stays, hair and soap build-up in the trap is likely the cause.
