Pump Case – Modular Water System Build Guide

This build guide documents the complete design and construction of a compact, modular Pump Case for mobile and off-grid water systems. It is based on real-world use, engineering best practices, and a strong focus on durability, serviceability, and safety.

Across 37 pages, the guide walks you step by step through the complete system — from component selection and mechanical layout to electrical wiring, filtration, UV treatment, and commissioning.

This is a hands-on engineering guide created for people who want to build a water system they can trust.

What this guide covers:

• System concept and design philosophy
• Component selection with clear technical reasoning
• Stainless steel components and flexible stainless braided hoses
• Electrical system design (12 V DC / 230 V AC separation)
• Proper fusing, cable sizing, polarity checks, and safety considerations
• Pump integration and pressure management
• Pre-filtration, activated carbon filtration, and UV disinfection
• Thread standards, fittings, sealing methods, and common pitfalls
• Assembly steps with practical tips from real builds
• Testing, commissioning, and troubleshooting
• Maintenance and service recommendations

All decisions are explained clearly, so you understand why a component is used — not just how.

Who this guide is for

• Overlanders and travellers building reliable water systems
• DIY enthusiasts who value quality and long-term reliability
• Engineers and makers who want a clean, well-documented solution
• Anyone who prefers stainless steel over plastic, and proper design over shortcuts
