Why small signs matter
Most plumbing problems start small. A tap that drips a little, a drain that empties a bit slower each week or a faint stain on the ceiling are easy to ignore. Left alone, they can turn into a flooded floor, a damaged cabinet or a dispute with a neighbour.
This article walks through the common warning signs, what you can check safely on your own, and when it is time to call a plumber. It also covers the cases where the right first call is your Town Council or management office rather than a private company. For the broader picture, the plumbing guide explains how to compare plumbing companies.
Signs you should not ignore
These are the signs that most often lead to a plumbing job. Some can wait a few days; others are worth acting on the same day.
- A tap that keeps dripping after you close it firmly: usually a worn washer, cartridge or mixer part.
- A drain that empties slowly or gurgles: a partial choke that tends to get worse over time.
- Water around the base of the toilet bowl: a seal or connection problem that can damage the floor.
- A toilet that keeps running after flushing: often a faulty flush valve or float in the cistern.
- Low water pressure at one tap only: a blocked aerator, a faulty tap or a problem in the pipe to that point.
- Damp patches, stains or bubbling paint on walls or ceilings: a possible hidden leak that needs tracing.
- A water heater that leaks, trips or gives no hot water: stop using it and have it checked.
What you can safely check yourself
A few simple checks can tell you whether you need a plumber at all, and they help you describe the problem clearly if you do.
For a slow basin or sink, remove and clean the stopper and the strainer, where hair and food often collect. For a dripping tap, check whether it is the spout or the handle that drips, since that tells the plumber which part may be worn. For low pressure at one tap, unscrew and rinse the aerator at the tip of the spout.
If a toilet keeps running, lift the cistern lid and see whether the float is stuck or the flush valve is not sealing. Do not force parts that do not move freely.
Avoid pouring strong chemicals into a choked drain again and again. If the first attempt does not clear it, the choke may be further down the pipe, and repeated chemicals can make the plumber's job harder.
When to call a plumber
Call a plumber when a problem keeps coming back after your own checks, when you cannot find the source of a leak, or when the job involves replacing fittings, pipes or a water heater. Leaks inside walls, under floors or behind cabinets usually need someone with the right tools to trace them without unnecessary hacking.

Compare plumbing companiesFor water-supply and sanitary plumbing work, PUB's requirements for plumbing works explain which work must be carried out by a licensed plumber. Ask the company whether your job falls into that category and who will do it.
When to call your Town Council or management office first
Not every leak is yours to fix. Problems in shared pipes, such as a common drainage stack or a corridor pipe, are normally handled by the Town Council for HDB estates or the management office for condominiums.
If water is coming through your ceiling from the flat above, read HDB's ceiling-leak guidance to understand how the inspection and repair process works for flats. It usually helps to speak to your neighbour and follow that process before you book any repair yourself.
Once the source is confirmed to be inside your own home, a private plumber is the right call.
What tap work costs, from published rates
Tap replacement and repair are among the most common plumbing jobs, and several companies publish their rates. The table shows the lowest matching rate each company publishes, with its source and capture date. These are advertised rates with conditions, not quotes, and they may not include the tap itself.

How to describe the problem
A clear description gets you a better answer on the first call.
- Say where the problem is, such as the kitchen sink, the common bathroom or the water heater.
- Say when it started and whether it is getting worse.
- Share a photo or video of the fitting, the pipe or the stain.
- Say whether your home is an HDB flat, a condominium or a landed house.
- Ask for the inspection or call-out charge, and agree the price of any extra work before it starts.
The leak repair guide and the choked drain guide explain what to describe for those jobs in more detail.

How do I know if a leak is inside my flat or from a shared pipe?
Look at where the water appears and where it comes from. Water from the ceiling often comes from the unit above, and leaks from corridor or common pipes are shared. If you are unsure, contact your Town Council or management office first, then book a plumber once the source is inside your home.
Should I try to clear a choked drain myself?
You can clean stoppers and strainers safely. If the drain is still slow after that, call a plumber rather than using strong chemicals repeatedly, since the choke may be further down the pipe.
What should I ask a plumber before the visit?
Ask for the inspection or call-out charge, whether parts are included in the price and how they will handle extra work if they find another problem. Agree any extra work before it starts.
