City Environmental Engineering Co.,Ltd provides 24 – hour drainage service to residential in Hong Kong, including apartments, village houses, public or private housing, etc.
The Common Area In Residential Properties Where Blockages Can Occur
Kitchen Sink Drain
Cause : Accumulation of grease in the pipes or blockage by kitchen waste in the grease trap.
The methods to unclog kitchen sink : Open the grease trap for preliminary cleaning and attempt to unclog it by using a drain plunger. If there is an excessive amount of grease, you may contact City Environmental Engineering co.,Ltd our professional technicians will use high – pressure water jet to help you solve the problem.
Blocked Toilet
Cause : Large of tissues, kitchen waste, paper towels, feminine hygiene products, or hard object falling into the toilet bowl.
The methods to unclog toilet bowl : You may try using a plunger to unclog the toilet. However, if the toilet bowl has an air vent, pumping may not be effective. In this case, you may contact City Environmental Engineering Co.,Ltd, our professional technicians will use high – pressure water jet to help you solve the problem.
Bathtub
Cause : The bathtub drains slowly due to the presence of hair or even pets hair.
The methods to unclog bathtub : You may try using a plunger to unclog the bathtub drain and use a bent wire to attempt to retrieve the trapped hair. If this methods do not work, you may contact City Environmental Engineering Co.,Ltd, our professional technicians will use high – pressure water jet to help you solve the problem.
Floor Drain
Cause : Not using a floor drain strainer to prevent scattered hair from entering.
The methods to unclog floor drain : You can try using a plunger to unclog the drain and use a bent wire formed into a hook shape to attempt to retrieve the trapped hair. If the methods not work, you may contact City Environmental Engineering Co.,Ltd, our professional technicians will use high – pressure water jet to help you solve the problem.
Equipment
** The selection of equipment will depend on the construction situation and quotation at the time. **
Movable High – Pressure Water Jet Vehicle
Movable High – Pressure Water Jet Vehicle are suitable for use in high-rise residential buildings. Although their water pressure is relatively lower than that of large high-pressure drain cleaning vehicles, the cleaning effect is comparable. The result is a clean and tidy effect achieved with just one hit.
Portable CCTV Survey Machine
Portable CCTV Survey Machine can be used to enter narrow drainage pipes and capture clear images of the interior of the pipes. By reviewing the recorded footage from inside the drainage pipes, the channel problem and its solution can be further analyzed, such as whether there are cracks, deformations, or improper debris in the channel. CCTV inspection helps us accurately identify the defective location in the channel, which can greatly reduce the time and effort needed for repairs.
Movable Water Vacuum
Movable Water Vacuum is used specifically for installing and removing toilets. Its principle is similar to that of a vacuum cleaner, which uses high-pressure fans, vortex fans, vortex air pumps, and other equipment to create a vacuum inside the toilet bowl. The negative pressure rapidly increases, and the high pressure quickly sucks the water into the interior of the barrel through a soft hose.
High – Pressure Water Jet Vehicle
High – Pressure Water Jet Vehicle is a method used to clean clogged drainage and sewer pipes. Its principle involves using a high-pressure hose fitted with jetting nozzles to pump water (stored in a tank) through the pipes. This process forces a powerful stream of water into the pipes, allowing workers to aim at the blockage and clear it.
The Common Symptoms Of A Clogged Household Drain
Toilet Water Level Decreases
The water level in the toilet bowl may be lower than usual, or during flushing, the water may rise and then slowly drain away.
Slow Drainage
Water accumulates on the drain or on the garbage, and then drain slowly instead of immediately. Over time, the blockage will worsen as any items ( such as food residues and hair ) that enter the pipe will be unable to pass through the obstruction.
Foul Smell
Over time, the trapped materials that causing the blockage begin to decompose, leading to stagnant water and causing foul odors in all affected drains, sinks, bathtubs, and around the bathroom.
Noises Heard While Draining
Bathtubs, sinks, or showers affected by a blocked drain may produce a harsh or grating noise as water struggles to drain freely.
