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.

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer.
