Cua Nam Ward (Hoan Kiem), with its interwoven network of old streets and alleys like Nguyen Khuyen, Le Duan, and Nguyen Thai Hoc, constantly faces chronic drain blockage issues. Due to an aging drainage system, small pipe diameters, and the heavy flow from hotels and restaurants in the old quarter, pipe blockages occur “like clockwork”. Just one downpour or a bit of excess grease and waste getting into the drain is enough to turn your bathroom into a foul-smelling “pond”.

Understanding this nuisance, Moi Truong Xanh offers drain unclogging service in Cua Nam Ward using the most advanced pipe-navigating technology of 2026. We commit to resolving toàn diện of blockages in just 15 minutes of operation, preserving the aesthetics and structure of your old house.

1. The Obsession with Clogged Drains in Cua Nam Old Quarter - Why DIY Solutions Always Fail?

Many households in Cua Nam have tried pouring dozens of bottles of drain cleaner acid or using poking rods, but the situation only worsened:

Old pipe systems are prone to cracking: Strong drain cleaner acid will corrode the brittle plastic layer of old pipes, causing underground leaks beneath the foundation, leading to structural subsidence.
Waste stuck deep in pipe joints: The old quarter has many L-shaped and T-shaped drain sections. Ordinary poking rods cannot reach blockages located dozens of meters deep.
Grease calcified hard as rock: In restaurants in Cua Nam Ward, accumulated grease adheres to pipe walls, forming white, plaster-like blocks that completely seal off the drains.

2. Moi Truong Xanh’s 4.0 Drain Unclogging Technology Rescues Cua Nam Ward

To completely resolve blockages without damaging the old quarter’s tile structure, we apply a set of solutions:

Nano-Spring Machine for Twisting and Hooking Debris

Unlike older machines that cause vibrations, Moi Truong Xanh’s nano-spring machine uses a flexible fiber-wrapped drilling head. The machine expertly navigates sharp bends in bathroom drains, breaking down stubborn hairballs, toilet paper, and hard plastic waste, then gently pulling them out.

HD Endoscopic Camera - The “All-Seeing Eye” Inside the Drain

We don’t guess the cause of the problem. Technicians will insert a super HD endoscopic camera deep into the drains of Cua Nam Ward. This clearly reveals if the cause is tree roots puncturing, calcification, or hard objects falling in, allowing for targeted solutions and saving homeowners 70% of time.

Hydraulic Compressed Air Plunger

For minor clogs caused by air pressure, we use a high-pressure compressor to push a powerful stream of air through the obstruction, restoring clear flow to the toilet in just a few seconds of flushing.
