Piccadilly is the valley floor below Mount Lofty, deep soil and market gardens with houses dotted along the road and up the sides. It is the coldest, foggiest, wettest pocket in this part of the Hills, and that matters more for drainage than almost anything else. Adelaide Hills Blocked Drains is a local referral service. We connect Piccadilly households with licensed local drain plumbers we work with who service the area.
Why Piccadilly drains block
Groundwater. The valley holds water, and in winter the soil profile stays close to saturated for weeks at a time. A septic soakage area in that ground cannot shed what it is given, so the whole system runs full and the house drains slow down behind it. People often assume a blockage and get a clear that changes nothing, because the pipe was never the problem.
Where the pipe is the problem, it is usually roots or silt. Garden trees and windbreaks find any joint that leaks, and runoff from the slopes carries soil into stormwater pits and the flatter lengths of pipe on the valley floor.
Properties here are generally unsewered, which makes the drains, the tank and the disposal area all the owner's responsibility. Your council can confirm what applies to your address and what the local wastewater requirements are.
What clearing a blocked drain involves
The licensed drain plumbers we work with usually start with a CCTV drain camera, which is the fastest way to separate a blocked pipe from a system at capacity. Jet blasting clears roots and silt, blocked stormwater lines on the valley floor are flushed through, and a damaged pipe can be repaired with pipe relining.
Pumping out a tank 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.
Frequently asked questions
We cleared the drain and nothing improved. What went wrong?
Usually the pipe was never the fault. On wet valley ground, a soakage area that cannot take water backs the system up regardless of how clean the pipes are.
Can stormwater be getting into the septic system?
It can, through a cracked lid, an open inspection point or a surface drain discharging in the wrong place, and it overloads a tank quickly. A plumber can trace it.
Is there any point in a camera inspection if we think it is the soakage area?
Yes, because it rules the pipes out properly. That is what tells you to call a different trade instead of clearing the same line again.
