Introduction to Home Plumbing

Plumbing issues are among the most common problems homeowners in Singapore face. Whether it's a dripping faucet, a clogged drain, or a running toilet, understanding the basics can save you money and prevent water damage.

1. Leaky Faucets

A leaky faucet is not just annoying—it's wasteful. A single dripping faucet can waste up to 3,000 gallons of water per year. Most leaks are caused by worn washers or seals that need replacement.

How to fix it: Turn off the water supply, disassemble the faucet, replace the worn washer, and reassemble. If the problem persists, you may need to replace the entire cartridge.

2. Running Toilets

A running toilet can waste up to 200 gallons of water daily. The most common cause is a faulty flapper valve in the tank.

How to fix it: Check if the flapper is sealing properly. If not, replace it with a new one. You can find replacement kits at any hardware store for under $20.

3. Clogged Drains

Clogged drains are caused by hair, soap, and debris buildup. Use a plunger or drain snake to clear minor clogs. For stubborn clogs, consider using a drain auger.

4. Low Water Pressure

Low water pressure can indicate mineral buildup in aerators or a more serious issue with your main water line. Start by cleaning the aerator on your faucet.

When to Call a Professional

If you notice water stains on ceilings or walls, hear strange noises in your pipes, or have persistent low pressure, it's time to call a professional plumber. These could indicate serious issues like burst pipes or water leaks behind walls.
