Kingsgrove is a mix that few St George suburbs share: established residential streets on one side, a light industrial and commercial area on the other, and the M5 East corridor cutting through. That mix means drain problems here range from a backed up laundry in a postwar cottage to a blocked grease line at a warehouse kitchen. St George Blocked Drains is a local referral service, connecting Kingsgrove homes and businesses with licensed local drain plumbers we work with.
Why Kingsgrove drains block
Most of Kingsgrove's houses were built through the middle of last century, many in brick on modest blocks. Plenty still run on their original clay sewer lines. Those lines have joints every metre or so, and once the joints shift, roots from street trees and backyard plantings move in. It is the most common cause of repeat blockages in the suburb.
Around Kingsgrove Road and the industrial pockets, the issues are about load. Commercial kitchens, wash bays and amenities blocks put more through a drain than a house ever does, and sediment, grease and packaging find their way into the lines. Stormwater from large roofs and hardstand areas also needs pits and pipes that are kept clear, or the first heavy storm overwhelms them.
Ground conditions vary across the suburb, and some blocks sit lower than the street. On those properties, stormwater can collect against the house if the system is not working, so a blocked pit or downpipe matters more than it would on a high block.
What clearing a blocked drain involves
The licensed drain plumbers we work with typically locate the blockage first, using the overflow relief gully or an inspection opening, then clear it with an eel or a high-pressure jetter. On older lines a CCTV drain camera is worth having, because it shows whether the pipe is sound or broken. For sites with grease or silt, jet blasting is the standard method. If stormwater is the problem, see blocked stormwater.
Typical pricing: a standard clear runs $150 to $400, root clearing $250 to $600, a camera inspection $249 to $600, and camera plus jetting $350 to $900. Relining a damaged section typically costs $3,000 to $8,000 or more. Larger commercial lines are quoted on inspection.
Frequently asked questions
Can I get a quote for a commercial or industrial property in Kingsgrove?
Yes. Mention the type of site and what the drain services when you send the form, and the enquiry goes to a licensed plumber who handles commercial drainage.
Water pools near my back door when it rains. What is causing it?
Usually a blocked stormwater pit, a silted pipe or a downpipe that is not connected properly. A plumber can jet the line and camera it to find the fault.
Every drain in the house is slow at once. What does that mean?
That points to the main sewer line rather than one fixture. Stop running water and get the line checked before it backs up inside.
