Chevalier Garden Drain Services

According to a Sing Tao Headline report of 17 March 2026, a pipe burst on the pavement outside the estate on Hang Shun Street at about 5pm that day, and the Water Supplies Department confirmed it was a salt-water main supplying flushing water to Tai Shui Hang Village and Chevalier Garden, with repairs and restoration targeted for 6pm the following day. To be clear: a burst supply main is a water-supply incident, not a broken drain. But during a day or two without flushing water, people flush with a bucket or sparingly, and too little water fails to carry solids and paper away, so a blockage or slow drain can appear days later; the first draws after restoration may also bring rust and sediment. While supply is off, flush with one full bucket in a single pour and put paper in the bin; once supply returns, flush a few times with clean water and watch how quickly the toilet clears.

According to a Hong Kong 01 report of 29 November 2016, about half a metre square of concrete fell from a bathroom ceiling in one flat, exposing the reinforcement; the report quoted the district councillor for the area at the time, Michael Yung Ming-chau, saying that there were a number of similar cases in the estate, usually large areas of render on kitchen or bathroom ceilings, and that after Buildings Department staff had inspected, some cases were confirmed as neither an upstairs leak nor a pipe leak. So a stain does not automatically mean a broken drain above. In practice: dripping only after someone upstairs showers usually points to waterproofing; clean water dripping continuously even when the flat above uses none points to a supply pipe; a smell that worsens when water is used or a toilet is flushed upstairs is the pattern that fits a leaking drain. The department to approach and the way costs fall differ in each case, so photograph and time-stamp rather than guess.

According to a Hong Kong 01 report of 11 December 2016, an owners' general meeting at Chevalier Garden voted on external-wall seepage, concrete spalling and roof waterproofing and rejected repairs "at this stage" by a large majority. Collective decisions like that affect when the shared pipework is inspected and renewed, but they do not change responsibility inside a flat: an owner can still have a technician check and clear their own branch pipes. As a general inference from building age, once scale builds up inside stacks completed in 1987–88, the low-floor flats in a vertical line are the first to see the water level rise and hear gurgling. The giveaway is scope: if only one fitment is slow, the branch pipe or trap is the likely cause; if the toilet, floor drain and kitchen sink slow together and it worsens while flats above use water, report a building drain to the management office rather than simply pouring drain cleaner in at home.

The Chinese Wikipedia records that Chevalier Garden was built on natural ground rather than reclamation, with the hillside and Tai Shui Hang Village behind it and the sea in front. Inferring from that setting, heavy rain washes leaves, fine sand and mud off the slope into the gullies along planters, footpaths and podiums first; if the water drains away slowly it stands on the surface and, at worst, runs into ground-floor shops or a car-park entrance. These are rainwater gullies and are not connected to the foul drain serving your toilet: surface ponding should be reported to the management office so the catchpits and gratings are cleared, whereas an indoor floor drain welling up with a drain smell belongs to the foul system. Walking the estate before and after the wet season and photographing where leaves collect makes follow-up much faster.

Flats here have saleable areas of 39–55 m² and small bathrooms, and, inferring from their age, most will have been renovated at least once over nearly forty years — typically replacing the bathtub with a shower, moving the washing-machine outlet to the kitchen or a worktop, or relocating the basin. By design, such changes alter the length and fall of the branch pipes: more joints and a flatter run make it easier for hair and soap scum to settle. Some jobs also fit a shallower trap or remove the anti-syphonage pipe, so a flush upstairs pulls the water seal out. The Buildings Department stresses that altering a drainage system must be done by a registered contractor under the Minor Works Control System. If the odour or slow draining began after a renovation, check the altered points first — it is usually quicker than working through every section from scratch.
