Drain Cleaning in Kwai Tsing District

Keep fats and oils out of the kitchen sink (bin them cooled), fit hair catchers in showers, flush only the 3 Ps, and jet lines with known root intrusion every 12-18 months until the pipe is repaired or relined. Recurring blocks always have a physical cause worth diagnosing.

Generally you own the pipes within your property boundary, while shared or public sewers are the utility's (or body corporate's) problem. If sewage backs up from a shared line, report it to the utility before paying a private contractor — it may be cleared free.

Caustic supermarket products sometimes clear light soap/hair partial blocks, but they don't touch grease plugs or roots, they damage older pipes and seals, and they make the drain hazardous for the plumber who eventually opens it. For a fully blocked drain, go mechanical.

Kitchen lines: grease and food solids. Bathrooms: hair and soap scum. Toilets: wipes (including 'flushable' ones) and sanitary products. Outside: tree roots entering pipe joints and silt. Knowing the likely cause helps the plumber bring the right machine first visit.

After a second blockage in the same line, before buying a house, or when you suspect root intrusion or a collapsed pipe. The camera shows exactly what and where the problem is, so you fix the cause instead of paying for repeat clearances.

A drain snake (electric eel/auger) bores a hole through the blockage — fast and cheap, but debris and grease remain on pipe walls. Hydro jetting scours the full pipe diameter with high-pressure water, clearing grease, scale and roots properly. Jetting costs more but lasts longer for recurring blocks.

The 通渠 trade is fragmented with flyer-based operators quoting low and inflating after opening pipes. Protect yourself: agree the all-in price in writing before work starts, use registered companies, and involve building management for anything in communal stacks.
