Plumbing Basics: Essential Skills for Tradespeople

Basic plumbing skills save time and money. Whether you're a plumber expanding your knowledge or a general tradesperson handling simple jobs, understanding the fundamentals makes work easier.

Pipe Types and Uses

Different pipes suit different applications:

• Copper: Traditional choice for water supply, durable but expensive
• Plastic (PVC/CPVC): Cheaper, easier to work with, limited temperature range
• PEX: Flexible, freeze-resistant, good for retrofits
• Push-fit: Quick connections without soldering or crimping

Essential Plumbing Tools

A basic plumbing kit includes:

• Pipe cutters (different sizes for different materials)
• Adjustable wrenches and pipe wrenches
• PTFE tape and jointing compound
• Plunger and drain rods
• Pipe benders for copper work
• Compression fittings and spare washers

Stopping Leaks

The first skill: finding and stopping water. Know where isolation valves are located. Carry spare tap washers and olive rings. Temporary repairs using repair tape can buy time until a proper fix is possible.

Making Joints

Compression fittings work well for most connections - clean pipes, fit olives correctly, tighten evenly. Push-fit fittings need properly cut, deburred pipe ends. Soldered joints require practice but create strong, permanent connections.

Common Mistakes

• Over-tightening compression fittings (deforms the olive)
• Forgetting to drain down before working
• Using wrong materials together (galvanic corrosion)
• Ignoring building regulations for notifiable work

When to Call a Specialist

Some work requires Gas Safe registration or specialist knowledge. Boiler work, gas connections, and complex systems need qualified professionals. Know your limits and subcontract when necessary.
