A properly functioning camper sink transforms van life from camping to comfortable living. Whether you're washing dishes after a mountain adventure or cleaning up before a video call, having reliable running water makes van life infinitely more pleasant. But DIY portable sink systems can be tricky get it wrong, and you'll deal with leaks, poor water pressure, and frustrating maintenance issues that can ruin your adventures.
At The Vansmith, we've installed hundreds of van water systems in our Colorado facility, and we've learned what works reliably in real-world conditions. This comprehensive guide covers everything from basic DIY portable sink setups to professional camper sink installations, helping you choose and install the water system that matches your van life goals.
Understanding Van Water System Basics
The Four Essential Components
Every functional van water system requires four key elements working together:
Fresh Water Storage: Tanks or containers that hold clean water for cooking, cleaning, and drinking Water Pump: Creates pressure to move water from storage to your faucet Distribution System: Pipes, fittings, and connections that carry water throughout your van Waste Management: Gray water collection for used water disposal
Sink Water Pump Requirements
Why Pumps Matter: Gravity-fed systems work for basic needs, but a proper sink water pump provides the pressure needed for comfortable washing, cooking, and cleaning. The difference between a trickle and a proper stream affects everything from dishwashing efficiency to hand cleaning comfort.
The Vansmith Standard: Our van water systems use reliable 12V pumps that provide consistent pressure for comfortable daily use while operating efficiently from your van's electrical system.
