Forest Range sits on high ground in the eastern Hills, orchard and bush country with properties on large blocks and long driveways off the main road. It is cold, wet and well treed, and every property manages its own wastewater. Adelaide Hills Blocked Drains is a local referral service. We connect Forest Range households with licensed local drain plumbers we work with who service the area.
Why Forest Range drains block
Altitude brings rain, and rain brings the two problems that define drainage here. Stormwater running off slopes and unsealed tracks carries soil, bark and gravel into pits and the flatter lengths of pipe, and saturated winter ground reduces how fast a soakage area can take what the house sends it.
Roots are the other factor. Remnant bush, orchard rows and windbreaks all search for water, and on a block that dries out properly in February the inside of a drain line is the most reliable supply available. Properties still running old clay pipe lose that contest at the joints.
Because this is a septic district, the drains, the tank and the disposal area are all the owner's responsibility. It also means three possible explanations for the same symptom, and working out which one applies is the whole value of the first visit.
What clearing a blocked drain involves
The licensed drain plumbers we work with usually start with a CCTV drain camera, then clear the line with jet blasting, which scours the pipe wall rather than punching through the blockage. Where tree roots in drains have cracked the pipe, relining the damaged section is usually the lasting fix.
Tank pumping is a licensed liquid waste contractor's job with a tanker, and the plumbers referred here do not do it.
A standard clear typically costs $150 to $400. Root clearing typically runs $250 to $600. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. If roots have broken an old pipe, relining typically costs $3,000 to $8,000 or more. Travel to the high country may be reflected in the call-out.
Frequently asked questions
Our system only struggles in the wet months. What should we do?
Have the pipes checked and ruled out first. If they are clear, the issue is capacity in the disposal area, which is a wastewater question rather than a drain clearing one.
Does fog and cold really affect a septic tank?
Low temperatures slow the biological activity in a tank, which is part of why winter problems are more common than summer ones.
Can a plumber find a tank nobody has seen for years?
Often yes, by tracing the line from the house. It is one of the more useful things a camera and locator do on an older rural property.
