Antons Plumbing & Gas is a fully licensed, family-owned company with over 25 years of proven expertise delivering reliable blocked drain solutions across Sydney’s residential and commercial properties.
The most common culprits behind blocked drains in Thornleigh include invasive tree roots penetrating aging pipes, sand infiltration, deteriorating infrastructure, and years of accumulated debris. Rather than quick fixes that leave you calling plumbers repeatedly, we use advanced CCTV camera technology to identify the exact problem, then deploy high-pressure hydro-jetting that clears blockages thoroughly and keeps your drains flowing freely for the long term.

Our plumbers first determine whether the obstruction affects one fixture or a larger section of the drainage system. Depending on the findings, our blocked drain services may involve high-pressure water jetting, mechanical clearing or a CCTV inspection.
Common warning signs include slow drainage, gurgling sounds, unpleasant odours and water rising in a toilet before draining. Wastewater returning through a shower, floor waste or outdoor drain can indicate a more serious blockage.
Recurring blockages may be caused by grease, wipes, tree roots, damaged pipe joints or debris remaining inside the drainage line. A professional inspection can identify whether the pipe requires further cleaning, maintenance or repair.
Yes. Our drain camera inspections help locate blockages and identify tree roots, cracks, displaced joints or deteriorated pipework. The findings help determine whether clearing alone is sufficient or whether repairs should be considered.
Yes. Anton’s Plumbing & Gas provides toilet repair services for blockages caused by excess toilet paper, wipes, foreign objects or problems deeper within the drainage line. Avoid repeatedly flushing an overflowing toilet because this may spread wastewater across the bathroom floor.
Stop using fixtures connected to the affected drain and keep children and pets away from any wastewater overflow. The emergency plumber guide also recommends clearing access to the problem and gathering information about what happened before the plumber arrives.
A plunger may help with a minor blockage close to a sink, shower or toilet opening. Follow the steps in this blocked drain guide, but stop when wastewater continues backing up, the blockage repeatedly returns or several fixtures are affected.
High-pressure water jetting can break apart grease, sediment and stubborn debris before flushing it through the drainage line. The plumber should first assess the blockage and condition of the pipe to determine whether jetting is suitable.
Yes. Tree roots can enter small cracks or loose joints in wastewater pipes and continue growing until water flow becomes restricted. Clearing the roots may restore drainage, but damaged pipework may also require repair or ongoing maintenance.
A blockage affecting only one sink, shower or toilet may be close to that fixture. When several fixtures drain slowly, gurgle or back up at the same time, the obstruction may be located deeper within the property’s sewer drainage system.
Treat the problem urgently when sewage is backing up indoors, wastewater is overflowing from an outdoor drain or several fixtures have stopped draining. Stop using the affected plumbing and arrange professional help to reduce contamination and property damage risks.
Yes. Our plumbers can investigate blocked toilets, sinks, floor wastes and shared drainage concerns in strata properties. Approval or coordination with the strata manager may be required when the affected pipe forms part of common property.
Yes. Anton’s Plumbing & Gas assists landlords, tenants and property managers with urgent and recurring drainage problems in Thornleigh. Tenants should report the problem promptly and confirm access or repair approval requirements with their landlord or managing agent.
Yes. Our plumbers can assist offices, retail premises, hospitality venues and other commercial properties with blocked sinks, toilets, floor wastes and sewer lines. Explain any access restrictions, operating hours or urgent sanitation concerns when arranging the service.
Heavy rain can overload wastewater systems when stormwater enters incorrectly connected or damaged drainage pipes. Leaves, soil and debris can also restrict outdoor drains and contribute to water pooling around the property.
Stop using water inside the property and keep people and pets away from the overflow. If neighbouring properties are also affected or the overflow continues when you are not using water, the problem may involve the wider wastewater network rather than only your private pipes.
The cost depends on the blockage location, property access, equipment required and whether damaged pipework is discovered. Anton’s Plumbing & Gas provides upfront pricing before approved drain-clearing or repair work begins.
Anton’s Plumbing & Gas offers a $0 call-out fee from 7:00am to 3:00pm on weekdays, subject to applicable terms and conditions. Confirm any charges that may apply outside these hours when making the booking.
Yes. Plumbing and drainage work in NSW must comply with the Plumbing Code of Australia and applicable NSW plumbing standards. These requirements apply to the installation, replacement, repair, alteration and maintenance of plumbing and drainage systems.
The AS/NZS 3500 standards cover water services, sanitary plumbing and drainage, stormwater drainage and heated water services. Licensed plumbers apply the relevant requirements alongside the Plumbing Code of Australia and NSW compliance rules.
