Our Plumbing Services in Singapore
Leaking Pipe & Tap Repair
Leaking pipes and dripping taps are among the most common plumbing issues in Singapore homes. Even a small drip can waste hundreds of litres of water per day, resulting in a high PUB water bill. AOT plumbers use quality fittings and pipes (PPR, CPVC, stainless steel) that comply with Singapore standards. We fix concealed pipe leaks, exposed pipe leaks, and replace faulty tap cartridges and washers.
Toilet Repair & Installation
We repair and replace:
- Cistern fill valves and flush valves
- Toilet seats and covers
- Bidet spray attachments
- Floor-mounted and wall-hung toilet pans
- Toilet flush mechanisms (continuous running, weak flush, no flush)
We work with all brands — American Standard, TOTO, Grohe, Duravit, and local brands sold at Hoe Kee Hardware or Selffix.
Pipe Installation & Replacement
Old galvanised iron pipes common in older HDB flats corrode and restrict flow over time. AOT replaces old pipework with modern PPR, CPVC, or stainless-steel pipes for better water pressure and cleaner water. We handle both concealed and exposed pipework, and can re-route pipes during renovation.
Basin, Sink & Bathtub Installation
Installing a new vanity basin, kitchen sink, or bathtub? AOT handles the full plumbing connection — supply lines, drainage, waste traps, and siliconing. We work alongside your ID or renovation contractor to ensure timely and clean installation.
Drainage & Choke Clearing
Blocked floor trap, kitchen sink, or bathroom drain? We use manual rodding and high-pressure jetting to clear obstructions. We also install and replace floor traps, U-bends, and gate valves.
Water Pressure Issues
Low water pressure can be caused by a failing water pump, partially closed gate valve, corroded pipes, or a faulty pressure regulator. AOT diagnoses the root cause and recommends the right fix — whether it's a pressure booster pump or a pipe replacement.
Common Plumbing Problems in Singapore HDBs
Older HDB flats (especially those built in the 1970s–1990s) often have ageing galvanised steel or UPVC pipes that corrode, scale up, or crack. Common issues include:
- Rusty or discoloured water from taps
- Sudden drop in water pressure
- Recurring toilet chokes
- Water seeping through the bathroom floor to the unit below
- Noisy pipes (water hammer)
If you are experiencing any of these, call AOT for an inspection. Early intervention is always cheaper than emergency repairs.
