Picture this: It’s Sunday morning, and you’re faced with a blocked sink just as your family arrives for lunch. Your heart sinks as the water rises. But here’s the good news – with basic plumbing knowledge, you can handle many common issues yourself and know exactly when to call a professional.
This guide will help you understand your home’s plumbing system and give you the confidence to tackle basic maintenance and repairs. You’ll learn which jobs you can manage safely and which ones need a qualified plumber.
Let’s start with how water reaches your taps. Your home gets its water in one of two ways:
- City Water Supply: Connected to your local water treatment plant, this system delivers treated water straight to your home. The water quality is monitored and regulated, but you’ll pay monthly bills and might face service interruptions during maintenance.
- Well Water: If you’re on a private well, you’ll have your own water source right on your property. While this means no water bills, you’re responsible for water quality testing and system maintenance.
From either source, water enters your home through a main supply line. Your main shutoff valve controls this flow – every member of your household should know its location. This is your plumbing system’s master switch.
Inside your home, a network of pipes branches out to deliver water where you need it. Each fixture (sink, toilet, washing machine) has its own shutoff valve. These smaller valves let you stop water flow to specific areas without affecting the whole house – quite handy when you’re fixing a dripping tap.
Now, let’s look at how water leaves your home. Your drainage system works mainly through gravity, carrying wastewater away through a clever network of pipes and components:
- Drain pipes slope downward, helping water flow smoothly toward the main sewer line or septic system. The angle matters – too shallow and waste moves slowly, too steep and solid waste gets left behind.
- P-traps are the curved sections of pipe under your sinks. They hold a small amount of water that blocks sewer gases from entering your home. They also catch items that shouldn’t go down the drain (like your favourite ring).
- Vent pipes extend up through your roof, helping water flow properly through drain pipes. They work like a straw – when you cover the top with your finger, liquid stays in place. Remove your finger, and gravity takes over.
Your drainage system connects to either the municipal sewer system or a septic tank. Regular maintenance of these components helps prevent nasty (and expensive) backups.
Your Essential Plumbing Toolkit
Before tackling any plumbing job, you’ll need these basic tools:
- Plungers (2 types): A cup plunger for sinks and a flanged plunger for toilets. They’re your first line of defence against blockages.
- Pipe Wrench and Adjustable Wrench: For gripping and turning pipes, nuts, and fittings. The pipe wrench has serrated jaws that grip rounded surfaces, while the adjustable wrench handles hexagonal fittings.
- Basin Wrench: This long-handled tool reaches those awkward nuts behind sinks. It’s a lifesaver when replacing taps.
- Plumber’s Tape: Also called PTFE tape, it creates watertight seals on threaded pipe connections. Always wrap it clockwise around threads.
- Drain Snake: A flexible cable that reaches deep into pipes to clear stubborn blockages. Manual versions work well for most household clogs.
- Safety gear is non-negotiable:
- Waterproof gloves protect your hands from harsh chemicals and bacteria
- Safety goggles shield your eyes from splashes and debris
- Open windows or run fans for proper ventilation when using cleaning products
Fixing Common Toilet Problems

Note: Always progress from least invasive to more aggressive solutions when dealing with any plumbing issue. If these DIY fixes don’t resolve the problem, it’s time to call a professional plumber.
Keeping an Eye on Your Pipes
Regular checks save you time and money. Here’s what to watch for:
- Water marks on walls or ceilings
- Unusual drops in water pressure
- A water meter that keeps running when no taps are on
- Higher water bills without increased usage
- Damp spots in cupboards or around appliances
Test your main water shutoff valve every six months. A stuck valve during an emergency isn’t fun! Mark its location clearly and show everyone in your household how to use it.
Water Heater Care
Your water heater needs regular maintenance to work efficiently. Here’s how to drain it:
- Turn off the power (electricity or gas)
- Close the cold water supply valve
- Connect a garden hose to the drain valve
- Open a hot water tap upstairs to prevent vacuum
- Open the drain valve and let the tank empty
- Turn the cold water on briefly to stir up sediment
- Repeat until water runs clear
Tank vs Tankless Heaters:
- Tank heaters need draining twice yearly
- Tankless units require annual descaling
- Both need regular temperature and pressure valve checks
Protecting Pipes in Winter
Frozen pipes can burst and flood your home. Take these steps when temperatures drop:
- Insulate pipes in cold spaces (loft, garage, outside walls)
- Keep your heating on low when you’re away
- Open kitchen and bathroom cabinet doors on cold nights
- Let taps drip slightly in freezing weather
- Seal gaps where cold air enters your home
Smart Water Usage
Save water (and money) with these simple changes:
- Fix leaky taps promptly – one drip per second wastes 3,000 gallons yearly
- Install aerators on taps to reduce flow without losing pressure
- Choose dual-flush toilets or add a water displacement device to your tank
- Take shorter showers – even five minutes less makes a difference
- Water plants with collected shower water while it warms up
Key Things to Remember:
- Don’t overtighten fittings – snug is enough
- Always wrap plumber’s tape clockwise on threads
- Use the right size pipes and fittings for proper flow
- Support pipes properly to prevent sagging and stress
Keep These Handy:
- Your local plumbing codes (especially for renovations)
- A maintenance log to track repairs and replacements
- Photos of your plumbing system when walls are open
- Contact details for emergency plumbing service
Your Emergency Action Plan:
- Know where to shut off water to individual fixtures
- Keep basic repair supplies ready
- Store your plumber’s number where everyone can find it
- Take photos of any damage for insurance claims
- Document repair costs and keep receipts
