Camper Van Fresh Water System Components

This bundle provides core components for a pumped fresh water system in a camper van. It includes the pump, a fresh water tank, an accumulator, and necessary plumbing parts. Ideal for self-builders looking to install a reliable water supply for sinks or outdoor showers.

Curated by The Shelf Curator · Updated June 2026

Built for self-build van lifers who need a pressurized plumbing system capable of handling multi-point fixtures like a sink and shower simultaneously. Not for minimalists using simple gravity-fed jugs — this shop focuses on fixed, interior-mounted components for high-volume storage.

Curator's pick: Shurflo 4008 Revolution Water Pump 3.0 GPM

The internal bypass design reduces the rapid cycling that typically causes noise and premature motor wear in low-flow situations. Its 55 PSI rating provides a consistent pressure gradient that matches residential-standard fixtures better than generic 12V alternatives.

⚠ Worth knowing: The inclusion of an accumulator tank is mandatory here, as the Shurflo pump's pressure switch can experience 'chattering' without a buffer, leading to inconsistent flow and increased electrical draw. The system also requires a dedicated winterization plan since PEX-B and plastic pump housings are prone to cracking if water expands in freezing conditions.

How to use this together

  1. 1

    Install Water Tank and Strainer

    First, securely mount the "NWTS 20 Gallon Fresh Water Tank" in your desired location, ensuring easy access for filling and cleaning. Then, connect the "Shurflo 255-313 Twist-On Pipe Strainer" to the water tank's outlet using PEX-B Pipe and SharkBite fittings; this protects your pump from debris right from the source, preventing future issues.

  2. 2

    Mount Pump and Accumulator

    Next, mount the "Shurflo 4008 Revolution Water Pump" in an accessible, dry location, following the manufacturer's guidelines for proper ventilation. Immediately after the pump (on the pressure side), install the "Seaflo Pre-Pressurized Accumulator Tank." This placement is crucial as the accumulator absorbs pressure fluctuations, smoothing water delivery and reducing the number of times the pump needs to turn on and off.

  3. 3

    Connect Plumbing to Fixtures

    Finally, run "PEX-B Pipe" from the accumulator to your desired water fixtures (e.g., sink, outdoor shower), using "SharkBite Push-to-Connect Fittings" for secure and tool-free connections. Ensure all connections, especially those involving the "Shurflo 182-200 Nylon Barbed Hose Fitting" at the pump intake, are tight to prevent leaks and maintain system pressure.
