Key takeaways
- One blockage can be bad luck. Two or three in a few months almost always means something in the pan or the pipe is catching waste.
- Hunter Water's rule is the three Ps: pee, poo and toilet paper. Wet wipes, paper towel and sanitary products go in the bin.
- If the shower or floor waste backs up when you flush, or the yard gully overflows, the blockage is in the drain past the toilet, not the toilet itself.
- After a repeat blockage, a CCTV camera inspection shows whether roots, a sag or a broken joint is the cause, so the repair targets the cause.
