Check Your Symptoms First

Blocked Drain Symptom Checker

Tick what is happening. We will tell you the likely cause and how urgent it is.

How this checker works: single slow drains usually mean a local blockage (hair, grease, an object) in that fixture's line. Several drains at once, gurgling, or anything coming back UP points at the main sewer line. A blockage that returns after clearing is the signature of tree roots or pipe damage, which is why we camera the line and show you the real cause before quoting the permanent fix as a fixed price.

What Actually Decides the Price

What Is Blocking It

Grease and objects clear fast. Tree roots need jet blasting and cutting. A collapsed section needs repair, not just clearing.

Where the Blockage Sits

A fixture line at ground level is quick to reach. A main sewer line deep in the yard or under concrete takes more.

How It Has to Be Cleared

Some blockages clear mechanically; stubborn lines need high-pressure jet blasting; damaged lines need a camera first.

One-Off or Recurring

A recurring blockage means the cause is still in the pipe. Clearing is temporary; the permanent fix is a separate, quoted decision.

When You Call

We answer 24/7. Business hours carry no call-out fee; after-hours and weekends may, always confirmed before we attend.

What Proof You Get

CCTV footage of the line, before and after, so you can see the cause and the result rather than take anyone's word.

Blocked Drain Questions, Answered

How much does it cost to clear a blocked drain in Sydney?

There is no honest flat number: the cost depends on what is blocking the drain, where it is, and how it has to be cleared. That is exactly why Mr Splash Plumbing quotes a fixed price on site before any work starts, so you approve the exact number first and there are no surprises.

Why won't a good plumber quote a blocked drain over the phone?

Because the same symptom has very different causes: a grease blockage near the kitchen, tree roots in the sewer line, or a collapsed pipe section. Each needs different equipment and time. A phone number would be a guess; a fixed on-site quote is a commitment.

What information gets me an accurate quote fastest?

Which drains are affected, whether it keeps coming back, any gurgling or smells, and photos if there is visible overflow. With that, we arrive with the right gear and confirm your fixed price before starting.

Do you charge to come and look?

No call-out fee during business hours, Monday to Friday 7am to 4pm. After-hours and weekend call-outs may attract a fee at our discretion, always communicated before we attend.

Is a blocked drain covered by insurance?

Sometimes, and it depends on the cause and your policy. Damage from sudden events is more commonly covered than gradual blockages. We provide CCTV footage and reports your insurer can assess.
