Drain Unclogging for Rental Homes — Prices Starting from 86K,...

Cầu Giấy District is known as the “capital” for students and migrant workers, with an extremely high population density in wards like Dịch Vọng, Mai Dịch, and Nghĩa Tân, where people live crammed into subdivided tube houses or mini rental rooms. Along with this vibrancy comes the heavy burden of an overloaded wastewater system.

The most common and haunting problem in this area is none other than: Toilets gurgling and overflowing, with soggy toilet paper waste floating sluggishly and refusing to flush. When a room is only 20m² and the bathroom overflows with foul odors, all daily activities are almost completely paralyzed.

📋 You will learn:

  • Why 70% of toilet clogs in Cầu Giấy rental homes stem from a small habit.
  • Warning about the risks of calling “99k Unclogging” flyer technicians found on utility poles.
  • Laser Camera inspection combined with Nano Spring Machine technique to clear deep clogs.
  • Clearly and transparently listed service price list.
  • Reading time: 8 minutes

The Hidden “Culprit” Paralyzing Toilets in Cầu Giấy

From the practical perspective of Môi Trường Xanh’s environmental engineers, while private homes often experience toilet clogs due to accidentally dropping hard objects, in Cầu Giấy’s rental houses and affordable apartments, the culprits are entirely different:

  1. Overuse of toilet paper (Durable, hard-to-dissolve wet wipes): Many young people have a habit of flushing toilet paper directly, especially durable multi-purpose types, and even nylon wet wipes down the toilet. The narrow toilet trap (especially in cheap rental unit toilets) cannot swallow the swollen, water-logged paper mass, leading to immediate clogging.
  2. “Non-standard” shared septic tank design: A 5-story tube house converted into 10 rental rooms, sharing a small septic tank originally built for a family of 4. The overload from the massive volume of wastewater prevents the biological septic system from breaking down waste quickly enough, causing wastewater to back up in a foul stream, filling the drain opening.

The “Nightmare” of Calling Unvetted Flyer Technicians

Amidst the panic of sewage overflowing to the bathroom door, many students hastily search for phone numbers spray-painted red like “99K Drain Unclogging” at the alley entrance.

The trap scenario begins: The technician arrives, performs a superficial plunger job, then claims “The machine needs to suction 10 meters of cable,” after which they falsely measure and present an exorbitant price list, charging millions of dong for a 5-minute operation. Annoyed and scared by the aggressive technician, many grudgingly transfer the money, bitterly regretting it and swearing never to call outside technicians again. This “scam” tarnishes the entire image of legitimate sanitation services in the Capital.

A “Healthy” Experience with Môi Trường Xanh’s Equipment Ecosystem

As a young, educated resident, you absolutely have the right to demand a service experience with clear invoices and advanced technological equipment, not just a bamboo plunger. Môi Trường Xanh establishes a “New Sanitation Standard” to quickly and efficiently solve problems for homes in Cầu Giấy with two cutting-edge tools:

1. Airflow Inspection Camera - No Falsely Reported Clog Depth

Immediately stops the “charging by the meter” trick. Before quoting a price, a tiny, pinky-finger-sized infrared camera head will be lowered into the toilet gap. The external HD screen will display with 100% clarity whether a sanitary pad is stuck at a depth of 0.5 meters or if the septic tank has collapsed. A technician’s words can be false, but an electronic lens cannot lie.

2. Foreign Object Retrieval with Nano Rotating Spring Cable

If tangled rags cause a clog, we don’t use a plunger to push them deeper. Môi Trường Xanh provides a coiled spring cable that, upon reaching the obstruction, activates an electromechanical spiral head (Coil Grabber) to firmly grip nylon/rags and professionally pull them back up, completely clearing the sludge buildup. Restores flow in just 10 minutes.

What You Need to Know to Avoid - Q&A

1. I dropped an air freshener in its cage into the toilet drain, and when I flush, it floats up. What should I do?

Immediately close the upright flush valve. Air fresheners with plastic cages often have very rigid clasps. The more you try to flush it down with water, the more it will get stuck horizontally in the siphon, eventually cracking the ceramic drain pipe. You need to call Môi Trường Xanh immediately to use an air blast gun to push it through the opening, preventing it from having time to adhere and cause the toilet to bulge or shift.

2. My second-floor room’s toilet always gurgles even though it’s not clogged?

The gurgling sound is due to the drainage pipe lacking a Septic Tank Venting System (Phi 21 pipe), which is particularly common in improperly renovated rental rooms. Pressure built up at the bottom of the tank forces water to find its way up. In the long run, there’s a risk of the tank exploding or extremely foul odors escaping. You need to call us for an endoscopic inspection and to add a ventilation system.

3. Can a toilet clogged with wet wipes be cleared with a spring machine on the same day?

Yes, in just 15 - 20 minutes. Our rapid response team in Dịch Vọng or Mai Dịch wards will be on-site within 15 minutes of receiving the information. We’ll neatly remove the rags without leaving a single trace of foul sludge on the rental room’s floor tiles.
