Find Out If Your Drain Issue Is Urgent. Answer a few short questions below to get a clear assessment.
Blocked drains rarely fail without warning. Most start small, then escalate into flooding, sewage smells, or repeated backups if left unchecked.
We built this Blocked Drain Severity Checker to help Sydney property owners quickly understand what’s likely happening and whether the issue needs urgent attention. It’s based on the same patterns our plumbers assess on-site every day across houses, units, strata buildings, and commercial properties.
Once completed, the checker provides a practical breakdown of your situation, including:
At Graham & Sons Plumbing, blocked drains are one of the most common call-outs we handle across Sydney. Over time, clear patterns emerge.
Slow kitchen drains behave differently from toilet backups. Gurgling and bubbling usually indicate pressure issues. Multiple fixtures backing up often point to main-line restrictions rather than a simple surface blockage.
This tool reflects those real-world patterns. It mirrors how our licensed plumbers assess blocked drains on-site before any equipment is brought in.
A blocked drain rarely improves on its own. In many cases, it becomes more compacted with use.
What often starts as slow draining can progress to:
Early identification makes a difference. Addressing the cause before pressure builds up helps avoid after-hours emergencies and unnecessary damage.
Certain symptoms tend to appear before more serious issues develop:
When more than one of these signs appears together, it usually indicates a deeper issue than a simple local blockage.
Once you call Graham & Sons Plumbing, you’ll speak directly with someone who understands blocked drains, not a call centre.
We’ll ask a few practical questions based on your symptoms, confirm the urgency, and explain the best next step. If attendance is required, we’ll arrange a licensed plumber to attend with the right equipment for the job.
Before any work starts, you’ll receive clear information on what’s involved and the expected cost. No surprises. No unnecessary upsells.
Some blocked drain situations require urgent action to prevent damage.
Call us immediately if you’re experiencing:
In these situations, continuing to use water can increase pressure in the system and cause further damage. Early intervention helps limit the impact and cost.
Blocked drains behave differently depending on the property type.
Houses often experience issues related to older pipework or tree roots. Apartments and units can involve shared lines, where one blockage affects multiple dwellings. Commercial properties typically deal with higher usage and grease buildup.
Our team works across all property types and understands the compliance and access requirements involved, including strata-managed buildings.
Blocked drains require more than a quick clear. They require accurate diagnosis.
