Single-handle faucets: Control water temp and pressure with one lever.

Double-handle faucets: Separate hot and cold controls.

Sensor faucets: Hygienic, touchless, often used in commercial bathrooms.

In Singapore, water-saving technology is also an important consideration due to national sustainability goals. Many modern taps are designed with aerators that reduce water usage without compromising pressure. Sensor taps, particularly in commercial or public spaces, prevent wastage and improve hygiene.

Tap and faucet installations require precision to ensure watertight seals, proper alignment with basins, and the right water pressure. A licensed plumber will use Teflon tape, rubber washers, and other sealing methods to ensure no drips or leaks develop over time.

Additionally, professional installers consider the water pressure in your home or building. High water pressure can damage certain faucet types over time, while low pressure may indicate a deeper plumbing issue that needs addressing. They can also install anti-scald devices for homes with children or elderly occupants to ensure safety.

Hiring a licensed plumber ensures correct fittings and long-term durability.

3. Toilet Bowl and Urinal Installation

Toilets and urinals play a major role in maintaining hygiene. Types include:

Close-coupled toilets: Compact and common in homes.

Wall-hung toilets: Sleek design, space-saving.

Urinals: Mostly for commercial spaces, must be installed precisely to avoid odour or drainage issues.

A properly installed toilet ensures efficient flushing, reduced water use, and minimal risk of leaks. In Singapore, the Water Efficiency Labelling Scheme (WELS) helps consumers select toilets that conserve water. Most modern toilets use dual-flush systems to reduce water consumption.

Urinals, on the other hand, require exact height measurements, appropriate drainage gradients, and reliable flushing systems to prevent foul odours. Incorrectly installed fixtures can lead to unpleasant smells and even damage to adjacent walls or floors due to hidden leaks.

Professional plumbers also handle the alignment of waste pipes and water inlets, ensuring there are no backflow issues. For homes and commercial premises, investing in expert installation is both hygienic and cost-effective in the long run.

Expert installation ensures proper flushing and prevents water leakage.

4. Water Heater Installation

Heaters must be installed to meet safety and energy standards. Options include:

Storage heaters: Suitable for large families.

Instant heaters: Great for small households; heat water on demand.

In Singapore, the compact nature of many HDB flats and condominiums makes instant heaters particularly popular. They are energy-efficient and take up less space, making them ideal for smaller bathrooms.

However, installation is not just about fixing the unit to a wall. It involves correctly connecting it to the electrical supply and water lines, ensuring all safety switches and pressure valves are in place. Storage heaters, due to their size and weight, often require ceiling or wall support checks and additional piping.

Licensed plumbers work in coordination with electricians (if required) to guarantee that the installation meets safety regulations and doesn’t pose any hazard to users. An incorrectly installed heater can lead to electric shocks, scalding, or water damage from leaks.

Improper installation can lead to electrical issues. Hire professionals for peace of mind.

5. Shower and Bathtub Installation

Shower and tub installation includes waterproofing, drainage, and tap fittings. Types include:

Rain shower or handheld units

Standalone or built-in bathtubs

The installation process starts with waterproofing the shower or bath area to prevent water seepage into walls or floors, which can lead to mould growth and structural damage. This involves applying waterproof membranes and sealants before tiling.

Next, plumbers ensure proper gradient and drainage systems are in place to avoid water pooling. This is especially important in freestanding bathtubs or open-concept showers.

Fixtures like thermostatic mixers are also installed to ensure consistent water temperature. These details enhance comfort while ensuring safety, particularly for children or older users. Whether it’s a sleek modern rain shower or a luxurious soaking tub, expert plumbing installation guarantees durability and functionality.

Licensed plumbers ensure waterproofing is done properly to avoid long-term water damage.

6. Plumbing for Fire Sprinkler Systems

Fire sprinkler systems are critical for safety, especially in commercial and high-rise buildings. Their plumbing network must be meticulously planned and installed.

There are two main types:

Wet pipe systems: Always filled with water; ideal for buildings where freezing is not a concern.

Dry pipe systems: Water is held back until needed; used in colder or sensitive areas.

Plumbers install these systems in coordination with fire safety engineers to ensure compliance with Singapore Civil Defence Force (SCDF) regulations. This includes pipe sizing, pressure testing, and integrating alarm valves.

Improper installation can lead to delayed activation during a fire, potentially endangering lives and property. Regular inspections and maintenance are also essential to keep systems operational.

Trust only licensed professionals for fire safety plumbing to meet local codes and save lives.

7. Sink and Basin Installation

Sinks and basins are found in kitchens, bathrooms, and utility areas, and their proper installation is vital for daily hygiene and usability.

Types include:

Top-mount sinks: Easy to install, common in kitchens.

Undermount sinks: Seamless look, more complex fitting.

Pedestal basins: Popular in bathrooms, hide plumbing pipes.

Installing a sink involves more than just mounting the basin—it requires precise alignment with water inlets and drainage pipes. A licensed plumber ensures tight seals to prevent leaks and uses anti-siphon traps to prevent bad odours from entering your home.

They also ensure the slope of the drain pipe is correct to avoid slow drainage or backflow. For kitchen sinks, garbage disposal units or grease traps may also be integrated.

Proper installation ensures smooth drainage and prevents water damage under cabinets or flooring.

8. Bidet Spray and Washlet Installation

Bidet sprays and washlets are increasingly popular in Singapore due to hygiene and comfort preferences.

Types of bidet installations:

Manual bidet sprays: Simple handheld sprayers.

Electronic bidet seats (washlets): Feature heated seats, warm water, and drying functions.

Installing a bidet requires tapping into the water line without disrupting the toilet's main supply. Licensed plumbers ensure proper pressure regulation and leak-proof connections. Electronic washlets may require electrical outlet installation, which means coordination with certified electricians.

Incorrect installations can lead to low water pressure, backflow contamination, or even flooding.

Professional installation ensures clean, safe, and comfortable bathroom experiences.

9. Drainage and Waste Disposal System Installation

Drainage is crucial to keep your environment clean and prevent flooding or structural damage.

Common installations include:

Floor traps: Prevent odour and backflow.

Grease traps: Required in commercial kitchens to filter fats and oils.\

Gully traps and drain lines: Direct wastewater safely away from the building.

Proper slope, pipe sizing, and ventilation are vital in drainage systems. Licensed plumbers use equipment like laser levels and pipe cameras to ensure accurate installation. Improper drainage can cause standing water, attract pests, and lead to costly repairs.

Singapore’s regulations also require anti-mosquito devices in certain drainage systems to prevent vector-borne diseases.

Effective drainage installation protects health, hygiene, and your building’s foundation.
