Drain jetting — also called hydro jetting — is a method of clearing blocked drains using high-pressure water. A specialised machine pumps water at very high pressure through a hose and nozzle inserted into the drain, blasting through grease, tree roots, sludge and debris. Unlike a drain snake, which pokes a hole through a blockage, drain jetting cleans the entire pipe wall, which means blockages are less likely to return. Square One Services owns its own drain jetting equipment and offers this service across Winston Hills, the Hills District and Western Sydney.

A drain snake (also called an electric eel) is a long, flexible cable that physically breaks up or pulls out a blockage. It's effective for simple clogs but doesn't clean the pipe walls, so grease and residue are left behind and blockages often return. Drain jetting uses high-pressure water to thoroughly clean the inside of the pipe, removing all buildup from the walls. It's the more permanent solution for recurring or stubborn blockages, particularly in older pipes or drains with tree root intrusion.

Recurring blocked drains usually mean the root cause hasn't been addressed. Common reasons include grease or soap scum coating the pipe walls, tree root intrusion growing back through hairline cracks, a partially collapsed or misaligned pipe, or a bellied section of pipe where debris pools. High-pressure drain jetting is usually the most effective solution for drains that keep blocking, as it thoroughly cleans the entire pipe rather than just clearing the clog.

Most blocked drain jobs are resolved within 1–2 hours, depending on the severity and location of the blockage. A straightforward blocked sink or toilet is often cleared faster. Stubborn or recurring blockages that require drain jetting may take slightly longer.
