Large, established trees in Northcote gardens often seek moisture from underground pipes. Small cracks in older pipes allow roots to enter, where they grow rapidly and cause major obstructions.

Once diagnosed, the most common intervention for a blockage is . Traditional electric eels (or drain snakes) are still useful for punching a hole through a blockage, but they can be abrasive to old pipes. Water jetting uses high-velocity water streams to cut through tree roots and scour the pipe walls of grease and sludge. It is a non-invasive method that cleans the pipe rather than just clearing a path.

You’re sipping a morning coffee on High Street, Northcote. The birds are singing, the tram rattles past—and then you hear it. A low, ominous gurgle from your kitchen sink. The water doesn’t drain. It stares back at you. Congealed fat, rogue pasta, and that “bio-friendly” soap block you bought at the PS Market have formed an unholy alliance. You, my friend, need a —fast.

Pouring cooking oils or fats down the kitchen sink is a leading cause of "fatbergs." These substances solidify as they cool, trapping other food waste and narrowing the pipe until it blocks completely.

Because in Northcote, we look after our heritage, our coffee, and our drains. In that order.

While aging infrastructure provides the context, the immediate causes of blockages vary.
