Plumbing Works Singapore
Pipe relocation, sanitary ware installation and water heater fitting — coordinated with waterproofing and tiling so nothing gets sealed in before it's tested.
Plumbing Sits Underneath Everything Else
Pipe relocation, sanitary ware and water heater installation almost always happen early in a renovation — before waterproofing, before tiling, before the room gets sealed up. Get the plumbing layout wrong at this stage and fixing it later means hacking back through finished work.
We sequence plumbing works with waterproofing and tiling so pipework is tested and confirmed before anything gets covered.
What's Covered
| Work | Typical Scope |
|---|---|
| Pipe Relocation | Moving water supply or waste pipes to suit a new bathroom or kitchen layout |
| Sanitary Ware | Toilet bowls, basins, taps and mixers — supply and installation |
| Water Heater | Storage or instant water heater installation and connection |
| Floor Trap & Drainage | Floor trap repositioning and drainage falls set correctly for water to actually flow to the outlet |
| Kitchen Plumbing | Sink connections, dishwasher and washing machine points |
| Leak Investigation | Tracing the source of an existing leak before deciding on repair scope |
Why Sequencing Matters
- Hacking — existing pipework and fittings exposed
- Plumbing first fix — pipes relocated or replaced to the new layout, pressure tested
- Waterproofing — membrane applied and ponding tested, only after plumbing is confirmed sound
- Tiling — floor and wall tiling over the tested, waterproofed surface
- Plumbing second fix — sanitary ware, taps and water heater installed and connected
PUB Compliance
Water supply fittings in Singapore need to comply with PUB's Code of Practice for water services (CP48) — this covers approved fittings, backflow prevention and connection standards. We use PUB-compliant fittings and materials as standard rather than treating it as an optional upgrade.
Common Plumbing Triggers During Renovation
- Bathroom layout changes — moving a toilet or shower position always means relocating supply and waste pipes
- Old galvanised pipework — older flats sometimes still have galvanised steel pipes prone to corrosion and reduced water pressure over time
- Low water pressure — often traced to pipe scaling or an undersized supply line rather than the water heater itself
- Kitchen island or peninsula additions — new sink positions need new supply and waste runs, which is easier to plan before flooring goes down
Plumbing Works FAQ
When during a renovation does plumbing work happen?
Plumbing is one of the earliest trades, carried out after hacking and before waterproofing and tiling. Pipes are relocated and pressure tested first, so any issues are caught before the floor and walls are sealed up.
Why does plumbing need to happen before waterproofing?
Waterproofing and tiling seal the surface. If plumbing changes happen afterward, fixing them means hacking back through finished tiling and re-doing the waterproofing membrane, which is far more disruptive than sequencing it correctly the first time.
What is PUB compliance and why does it matter?
PUB's Code of Practice for water services (CP48) sets standards for approved fittings, backflow prevention and connections in Singapore. Using compliant fittings isn't optional — it's the standard for any water supply work, and we use PUB-compliant materials as a matter of course.
Can you relocate my toilet or shower to a new position?
Yes. Moving a toilet, shower or sink to a new layout means relocating the supply and waste pipes and the floor trap, which is planned during the plumbing first-fix stage before waterproofing and tiling begin.
Why is my water pressure low after renovation?
Low pressure is often traced to pipe scaling in older galvanised pipework or an undersized supply line, rather than the water heater. We investigate the actual cause rather than assuming a fitting needs replacing.
Do older HDB flats often have plumbing problems?
Some older flats still have galvanised steel pipework, which corrodes over time and can reduce water pressure or eventually leak. This is worth checking during any bathroom or kitchen renovation on an older unit.
Can you investigate an existing leak before I decide on repair scope?
Yes. We trace the source of a leak first — it's not always where the water appears to be coming from — before recommending whether it needs a full waterproofing repair, a plumbing fix, or both.
