Common faults Common Leak Problems We Find
Most leak callouts here trace back to how the area was built. Redwood Park was formally established in 1959 and the bulk of its housing went up across the 1960s and 1970s as the north-east push past Modbury filled in toward the foothills. Decades on, the supply lines, drains and gas fittings throughout streets like Milne Road, Lokan Street, Cronulla Drive and Brassington Avenue throw up the same leak patterns:
01
Ageing storage hot water units leaking at the base
Many original 1960s and 1970s brick homes along Milne Road and the older Lokan Street pocket still run storage hot water units that are well into their second or third generation, and tanks now well past service life often surface first as a slow leak at the base before they fail outright.
02
Clay drain joints weeping at the seams
The earliest 1960s subdivisions were laid out before PVC drainage became the Adelaide standard, so a meaningful share of original homes still drain through earthenware clay pipework that cracks at the joints as the ground shifts and lets groundwater track back through the line.
03
Tree-root intrusion at hidden cracks
The area is dotted with mature council reserves like Cronulla, Brassington, Sunhaven, Eva and Kirk, and decades of established backyard plantings on standard suburban blocks regularly send roots into ageing drain lines, opening cracks that then weep back into the soil.
04
Slope drainage failures along the downhill side
The suburb sits on the lower slopes of the Mount Lofty foothills with a steady fall away from Grenfell Road toward the plain, so stormwater paths and gravity drain falls that have shifted over time often surface as damp ground or pooling water on the downhill side of properties.
