Is Sydney Water responsible for my blocked kitchen sink?

As the local water authority, Sydney Water is responsible for the main sewer lines. However, the pipes under your kitchen floor and leading to the boundary trap are the property owner's responsibility. In St Leonards apartments, the 'stacks' are often managed by the Body Corporate.

How can I prevent kitchen blockages in a high-rise apartment?

Avoid pouring roasting fats or oils down the drain. Because many St Leonards apartments have long horizontal pipe runs to reach the main stack, grease cools and solidifies faster than in a vertical setup, leading to frequent 'fatbergs'.

Can I use supermarket drain cleaners on my kitchen pipes?

While some minor hair clogs in bathrooms respond to plungers, kitchen grease is usually too dense. Chemicals can also damage older copper piping found in St Leonards' mid-century buildings. We recommend professional jetting for a long-term fix.

How long does it take to clear a kitchen drain?

Most standard kitchen sink clearances in St Leonards take between 45 and 90 minutes, depending on whether we can access the pipes via the sink trap or if we need to use a boundary shaft.

Why does my St Leonards kitchen sink keep blocking?

Almost always cooled grease coating the pipe wall. Jetting plus a strainer upstream stops the cycle.

Local note: St Leonards features a unique mix of high-density high-rises and heritage pockets near Naremburn, meaning drainage systems range from complex multi-storey stacks to aged earthenware pipes.

Why St Leonards Kitchen Drains Struggle

The drainage challenges in St Leonards are unique to its geography and architectural mix. In the newer high-density developments near the railway station, kitchen stacks often suffer from 'fatbergs'—masses of solidified cooking oils and detergents that travel through long horizontal runs before hitting the vertical drop. Because these buildings house hundreds of residents, a blockage in one unit can sometimes indicate a larger issue within the building's shared infrastructure.

In the older residential pockets toward Greenwich or Artarmon, we often find original copper or earthenware pipes. These materials are susceptible to sagging or internal corrosion over decades, creating rough surfaces where rice, coffee grounds, and grease snag and accumulate. Furthermore, the sandy loam soil characteristic of the Lower North Shore can cause slight ground shifts, leading to misaligned joints in older kitchen waste lines.

Our Process for Fixing Your Blocked Kitchen Drain

We don't believe in guesswork. Our approach to a kitchen sink not draining starts with a non-invasive CCTV camera inspection. This allows us to see exactly what is causing the obstruction—be it a foreign object, a build-up of organic matter, or structural pipe failure.

Once the blockage is identified, we typically use High-Pressure Water Jetting. Unlike traditional electric eels, which can struggle with soft grease or potentially crack older pipes, the water jetter scours the internal walls of the pipe. This removes the 'grease sleeve' entirely, returning the pipe to its full diameter. We perform this work through existing access points, ensuring your stone benchtops and custom cabinetry remain completely untouched.

Transparent Pricing for St Leonards Residents

The cost to clear a blocked kitchen sink in St Leonards typically ranges from $150 to $450, depending on the severity and location of the clog. Simple blockages located within the 'S-bend' or trap directly under the sink are on the lower end of the scale.

Grease and food waste in St Leonards kitchens

Kitchen drain blockages in St Leonards are almost always grease emulsified with cold water — it leaves the sink as a liquid and solidifies in the cooler section of pipe under the slab. Cable machines bore through but leave a wax-like coating that re-blocks within months. We jet the line, scour the wall back to bare PVC, then advise on a sink strainer and a no-fats-down-the-drain habit that prevents the next call-out.

For St Leonards apartments and townhouses on shared kitchen risers we coordinate with neighbours, body corporate, and (where needed) the strata managing agent so all stakeholders see the CCTV evidence and approve the fix.
