Project Overview

Many things can block a sink. Food scraps, hair or even tree roots can get into the drains. We show you how to unblock a sink and flush it with a cleaner to get rid of any residue.
Continue to step-by-step instructions

Step by Step Instructions

1 Pump the plunger over the drain hole
2 Flush the sink with drain cleaner
  • Step 1. Pump the plunger over the drain hole

    Place the plunger over the drain hole and pump the plunger. The suction cup has to be below the level of the water that’s standing in the blocked sink.  When it is unblocked the water will drain away nicely and you’ll have a free flow of water.
  • Step 2. Flush the sink with drain cleaner

    Use drain cleaner to make sure nothing else is left in the pipes. Put your gloves on and mix up the drain cleaner, following the instructions on the packet. Tip the drain cleaner down the drain and leave it to sit for the appropriate amount of time. Flush it through with clean water.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
