Complete Plumbing Guide

Chapter 1: Plumbing Basics

⚠️ Safety First: Always turn off water supply before starting any plumbing work. Wear safety glasses and gloves.

Understanding Your Plumbing System

A plumbing system consists of two main subsystems: the water supply system and the drainage system. Understanding how these work together is crucial for any plumbing work.

Water Pressure Basics

Normal household water pressure ranges from 40-60 PSI. Understanding pressure is essential for proper fixture installation and troubleshooting.

How to Check Water Pressure:

1 Attach pressure gauge to outdoor spigot
Use a threaded pressure gauge for accurate readings.

2 Turn on water fully
Open the valve completely for maximum flow.

3 Read the gauge
Normal pressure should be 40-60 PSI.

Chapter 2: Essential Plumbing Tools

Chapter 3: Essential Techniques

Soldering Copper Pipes

1 Clean the pipe and fitting
Use emery cloth to remove oxidation and create a bright surface.

2 Apply flux
Brush flux on both pipe end and inside of fitting.

3 Heat the joint
Use propane torch to heat fitting, not the solder.

4 Apply solder
Touch solder to joint – it should melt and flow around the connection.

PVC Pipe Installation

1 Measure and mark
Account for fitting depth when measuring pipe length.

2 Cut pipe square
Use pipe cutter or miter box for clean, straight cuts.

3 Deburr and clean
Remove burrs and clean with PVC primer.

4 Apply cement and join
Work quickly – PVC cement sets in 30 seconds.
