Blocked Sinks & Showers Lower North Shore
Slow kitchen sinks, shower puddles and bubbling floor wastes can begin locally or reveal a deeper branch restriction. Describe which fixtures are affected before choosing a treatment.

Signs You May Notice
- Water pools around a shower waste
- A sink empties more slowly each week
- Several nearby fixtures are affected
- Odours or bubbles come from the waste
Possible Causes
- Hair and soap residue
- Cooking fats and food debris
- Sediment in laundry or floor wastes
- A deeper branch-line restriction
Symptoms help guide investigation, but cannot confirm the cause on their own.
What to Do before the Visit
Stop adding water to the affected waste. Remove only loose surface debris if it can be reached safely; avoid chemical products and do not dismantle contaminated pipework.
If water is near electrical equipment or ground is unstable, stay clear and explain the hazard when calling. Urgent calls are taken 24 hours, 7 days a week.
How Diagnosis Guides the Work
We check the fixture trap and nearby drainage before choosing the least disruptive effective method. If several fixtures are involved, the investigation moves downstream rather than repeatedly treating one waste.
Trap cleaning or a compact mechanical machine may be enough for a local restriction. Persistent symptoms across several fixtures warrant downstream investigation. Clearing cannot correct a poorly graded or damaged branch.
Flow is checked after suitable clearing or repair. Maintenance advice and any remaining structural issue are explained separately.
Tools and Materials
- Hand tools and trap-cleaning equipment
- Compact mechanical drain machine
- Inspection camera for accessible branches
- High-pressure jetter when the pipework suits it
The operator selects the equipment for the obstruction, pipe condition and safe access. The most forceful method is not always appropriate.
Access Planning for Your Drain
Chatswood and Artarmon units may need shared branch access beyond the bathroom. In Crows Nest renovations, tell us which wastes were added or moved so the original and newer connections can be considered.

Follow the Problem beyond the Grate
Is one waste slow, or do the sink, shower and laundry affect one another?
Hair around a grate is visible; a restriction in a shared branch is not. We consider the trap and the connected wastes so that a deeper problem is not mistaken for surface debris.
How the Finding Changes the Work
An accessible trap may need cleaning. Symptoms across connected fixtures can justify investigating the branch. The available opening and pipe size affect which tools can be used.

A useful result includes knowing what to watch for next.
Day-to-Day Care
Empty strainers into the bin and collect cooled cooking fats for disposal instead of rinsing them into the sink. Remove accessible hair from the grate without pushing it further down.
When to Call Again
Note whether the waste slows on its own or only when another fixture runs. That detail is more useful than repeatedly adding cleaner.
Blocked Sinks & Showers Questions
Why does the shower pool while the basin works?
Hair or soap may be restricting the shower trap or branch. One normal fixture does not prove the entire drainage system is clear.
Can grease block a kitchen waste even with hot water?
Fats can cool and collect downstream. Flushing hot water does not reliably remove a developed deposit and may move it elsewhere.
What does a bubbling floor waste mean?
Air may be moving through a restricted connected branch. Report which other fixtures are in use when it happens.
Should I dismantle the trap before calling?
Do not dismantle contaminated or unfamiliar pipework. Describe access beneath the sink and any product already used; the plumber can plan safe handling.
