    Blocked Drains

    When a drain stops doing its job, disruption spreads quickly. Water lingers in bathrooms, kitchens, laundries, and outdoor areas, turning routine tasks into a nuisance. Richard Knight Plumbing traces the cause, clears the obstruction, and gets water moving as it should again. For Inner West properties, the focus is a clean resolution that holds up beyond the first flush and across your system.

    Blocked Sewers

    A sewer issue is not something to leave and hope for the best. Slow drainage, unpleasant smells, or repeated backups can point to a line that needs attention. Richard Knight Plumbing finds the source of the problem, explains what is happening, and restores dependable flow with a solution suited to your Inner West property. It helps minimise disruption to your property and routine.

    Blocked Sinks

    A slow or blocked sink can make a bathroom, kitchen, or laundry feel unusable far too quickly. Richard Knight Plumbing looks beyond standing water to identify what is causing the blockage, then restores clear flow with care. Whether it is a café, flat, home, or office, the aim is to get the space working normally again, with as little interruption as possible. We keep work neat and disruption low.

    Blocked Stormwater

    Stormwater needs to move quickly when rain arrives. When it cannot, water can collect around entries, gardens, paths, and roofs, putting extra pressure on your property. Richard Knight Plumbing checks the route from downpipe to drainage, then removes the restriction so rainwater is carried away where it belongs. That helps protect access, surroundings, and your building itself in wet weather.

    Blocked Toilets

    A blocked toilet calls for a calm, capable response. Overflowing water, poor flushing, and recurring blockages can affect everyone using the property, from a busy workplace to a family home. Richard Knight Plumbing identifies the cause, restores reliable flushing, and leaves you with facilities ready for normal use. The aim is to return the space to normal without needless fuss.

Reviews are flowing

  • I have used Richard a few times over the past ten years or so. He replaced my boiler when it sprung a leak, replaced a garden tap and pipe, fixed my drains and fixed my kitchen tap and pipes. I cannot recommend him highly enough. Richard is responsive, reliable, professional in his approach, personable and punctual. His fees are reasonable and his workmanship is always great. He also cleans up after himself. He takes pride in his work. I can't recommend Richard enough.

Frequently Asked Questions

  • What are the early signs of a blocked drain?

    Slow draining water is often the first sign, particularly in a shower, sink, or laundry tub. You may also notice gurgling sounds, unpleasant smells, water pooling outside, or a toilet that is taking longer to clear. Acting early can help prevent an overflow or a more disruptive blockage later.

  • Should I keep using water if the drain is backing up?

    It is usually best to stop using the affected fixtures until the issue is assessed. Continuing to run taps, flush toilets, or use appliances can add more water to a blocked line and increase the risk of an overflow. This is particularly important where wastewater is rising through a floor waste, shower, sink, or toilet.

  • Can tree roots cause a blocked drain?

    Yes. Tree roots naturally seek moisture and can enter older or damaged drainage pipes through small gaps, joints, or cracks. Once inside, they can catch debris and gradually restrict water flow. A recurring blockage, especially in an established Inner West property, may need further investigation to identify the underlying cause.

  • Do I need a drain camera inspection?

    Not every blockage requires a camera inspection. However, it can be useful when a problem keeps returning, the cause is unclear, or there are signs of a damaged pipe underground. Seeing the condition of the line can help determine whether the issue is a simple blockage, root intrusion, pipe damage, or something else.

  • What should I do before the plumber arrives?

    Make a note of which fixtures are affected and when the issue started. Avoid using the blocked area where possible, particularly if water is backing up. Clear access around sinks, toilets, floor wastes, or outdoor drainage points, and let us know about any previous plumbing work, recurring issues, or recent heavy rain.

  • Why does my toilet gurgle when I use water elsewhere?

    Gurgling can mean air is being displaced within the drainage system because water is struggling to move through a restricted pipe. It is often noticed when a washing machine drains, a sink empties, or a shower is running. A plumber can assess whether the issue is isolated or affecting a larger section of the line.

  • Why does stormwater overflow during heavy rain?

    Stormwater systems can struggle when leaves, sediment, or other debris restrict the path between gutters, downpipes, and underground drainage. Heavy rain may expose an issue that is not obvious in dry weather. Overflowing water around paths, entrances, or garden areas is worth checking before it reaches the building.

  • Why does the same drain keep blocking?

    A recurring blockage may mean the original obstruction was only part of the problem. Grease, hair, roots, scale, or a damaged section of pipe can all create repeat issues. Rather than simply clearing the line again, it is worth identifying why material is building up or why water is unable to move freely through the system.

  • Can one blocked drain affect several apartments or tenancies?

    It can. In larger buildings, shops, offices, and unit blocks, multiple fixtures may connect to shared drainage lines. A blockage further along the system can affect more than one bathroom, kitchen, or tenancy. Early reporting helps property managers, owners, and occupants limit disruption and coordinate access where needed.

  • When should I arrange urgent help for a blocked drain?

    Arrange prompt plumbing help when sewage is backing up, water is overflowing inside, your only toilet cannot be used, or a blockage is affecting several fixtures at once. Richard Knight Plumbing is available Monday to Friday, 7 am to 5 pm, and can assess blocked drain concerns across Sydney’s Inner West.
