Drain Unblocking Sydney — Blocked Drains From $49*

Answer:

Blocked drain clearing in Sydney starts from just $49* for standard blockages. The final cost depends on the severity and location of the blockage — for example, a simple kitchen sink clog will cost less than a deep sewer line blockage requiring CCTV inspection. At Mr Splash Plumbing, we provide upfront fixed pricing before starting any work, so there are no surprises. We also offer $0 call out fees and 0% interest payment plans.

Answer:

The most common causes of blocked drains in Sydney are tree root intrusion into underground pipes, grease and fat build-up (especially in kitchen drains), foreign objects flushed down toilets, hair and soap scum in bathroom drains, collapsed or cracked pipes, and heavy rainfall overwhelming stormwater systems. Tree roots are the #1 cause of blocked sewers across Sydney. A CCTV drain camera inspection can pinpoint the exact cause so you only pay for the fix that's needed.

Answer:

You can try a plunger or boiling water for minor surface-level clogs. However, most blocked drains in Sydney are caused by problems DIY methods can't reach — tree roots, deep grease build-up, or collapsed pipes. Using chemical drain cleaners can actually damage your pipes and make the problem worse. If the blockage doesn't clear with a plunger, or keeps coming back, it's time to call a licensed plumber. Our blocked drain service starts from $49*.

Answer:

Common signs of a blocked drain include: water draining slowly from sinks, showers or baths; gurgling sounds coming from your drains; bad smells from drains or outside grates; water pooling around floor drains; and toilets that won't flush properly or overflow. If you notice multiple drains in your home are slow at the same time, it likely means a main sewer line blockage — call a plumber immediately to avoid sewage backup.

Answer:

Yes, blocked drains almost always get worse if left untreated. A slow drain today can become a completely blocked pipe, sewage backup, or even a burst water pipe tomorrow. Tree roots continue to grow, grease continues to build up, and partial blockages trap more debris over time. The longer you wait, the more expensive the repair. Early intervention with high-pressure jet blasting (from $49*) is far cheaper than emergency pipe replacement.

Answer:

A blocked drain can be an emergency if it's causing sewage backup into your home, flooding, or if you can smell gas. In these situations, call Mr Splash Plumbing immediately on 1300 677 752 — we provide 24/7 emergency plumbing across Sydney with average response times under 5 minutes. Even if it's not an emergency yet, we recommend getting it looked at quickly before it escalates.

Answer:

Absolutely — tree roots are the number one cause of blocked drains and blocked sewers in Sydney. Roots seek out moisture and can enter pipes through the smallest cracks or joints. Once inside, they grow rapidly and create severe blockages. We treat tree root intrusion with high-pressure jet blasting to clear the roots, followed by chemical root treatment (ROOTX/VAPOROOTER) to prevent regrowth. For badly damaged pipes, pipe relining creates a new pipe inside the old one without digging.

Answer:

Pipe relining is a no-dig method of repairing cracked, broken or root-damaged pipes. A resin-coated liner is inserted into the existing pipe and cured in place, creating a brand new pipe within the old one. It's faster, less disruptive, and often cheaper than traditional pipe replacement. Our pipe relining comes with a 50-year product warranty. Cost depends on the length and location of the damaged section — contact us for a free quote.

Answer:

Most standard blocked drains in Sydney can be cleared in 30 to 60 minutes using high-pressure jet blasting. More complex blockages — such as deep tree root intrusion or collapsed pipes — may require a CCTV drain camera inspection first and could take 1–2 hours. Our team will give you a clear timeframe and upfront pricing before starting any work.

Answer:

To prevent blocked drains: never pour cooking oil or grease down the sink (wipe pans with paper towel first), use drain strainers to catch hair and food scraps, don't flush wet wipes or sanitary products (even “flushable” ones), and have your drains professionally cleared every 1–2 years as preventative maintenance. If you have large trees near your sewer line, regular root treatment can prevent costly blockages.

Answer:

Yes, all our blocked drain services are completely safe for pets, children and plants. Our primary methods — high-pressure water jetting and CCTV inspection — use no chemicals at all. When chemical root treatment is required, we use commercial-grade products that are applied directly inside the pipe and pose no risk to your household.
