Blocked drains in Liverpool

Blocked drain help in Liverpool

South-west clay soils swell and shrink through wet and dry years, working the joints of older earthenware sewers until roots find their way in — the classic reason a Liverpool drain blocks again months after it was cleared. Newer townhouse and granny-flat builds tie extra load into those same ageing street connections, and flat blocks drain slowly once stormwater pits silt up.

Liverpool's housing tells the story of each Sydney building boom: inter-war and post-war brick and fibro around the old core, seventies and eighties family homes through the surrounding suburbs, and a current wave of apartments, townhouses and secondary dwellings filling in every gap. The oldest streets still run vitrified-clay sewers that have spent decades in some of Sydney's most reactive clay soil — ground movement opens the joints, street trees and garden figs do the rest, and the same line chokes each time the roots regrow. Infill development concentrates more kitchens and bathrooms onto those original connections, so weak spots show up faster. The Georges River floodplain edges and generally flat falls mean stormwater has little help from gravity; silted pits and grated drains pool quickly in a south-west downpour. A CCTV inspection shows whether the fault is roots, a dropped joint, grease or silt, and whether jetting, a repair or a no-dig reline is the honest fix.
