A drip, a burst hose, or a thread left in the elbow
Cheap zinc-alloy angle valves dezincify. They shear flush with the tile when someone changes a bidet spray by force. The broken thread is still inside the copper or stainless elbow.
| What you see | Likely cause | What to do first / typical cost |
|---|---|---|
| Spray leaks at the handle or the hose | The set has aged | New spray and 2-way valve: S$110 to S$180 |
| The valve snapped during a DIY change | Zinc alloy sheared in the wall elbow | Extractor, no hacking: S$180 to S$320 |
| A braided hose is bulging under the sink | The stainless braid has let the inner tube swell | Pair of hoses and stopcocks: S$130 to S$220 |
| Several rooms still have the original valves | One burst will flood the flat | Whole-unit shield: S$260 to S$450 |

Plan Bidet sprays, 2-way valves, and snapped threads pulled without hacking
Isolate the stopcock or the heater switch before any fitting is loosened.
Photograph the existing joint so the replacement can match the thread and the outlet.
Do the repair on the existing point. Do not chase a new pipe unless a licensed plumber is on the job.
Run water, check the ceiling below if the bathroom is over another room, and wipe the joint dry.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Approval | Town Council hours for noisy work. An HDB permit only if the layout or a hack changes. | MCST by-laws, a water-shutdown window, and a deposit if the by-law asks for one. | No HDB permit. A new sewer run or a structural chase is still PUB or BCA, not a handyman visit. |
| Water | Like-for-like on the existing outlet stays maintenance. | The same rule, plus the building may shut the riser for a short window. | Long runs, pumps and tanks need the plumber to see the plant, not only the tap. |
| Access | Service yard and bathroom are usually reachable the same day. | Lift booking and protection of common areas come first. | A roof, a gutter or an external pipe may need safe access before anyone climbs. |

- Say if the water can be isolated from inside the flat
- Clear the cabinet under the sink
- Mention a condo shutdown or an HDB hacking rule if you already know it
- Keep children and pets out of the wet area during the visit
