STATE:
WATER
Plumbing is the most underrated part of a build. From pressurized showers to simple gravity systems, we reveal the logic of leak-free van life.
Submersible Pumps
The simple choice. The pump sits inside the tank and is triggered by a microswitch in the tap. Perfect for small vans and budget builds.
- Cheap & Silent
- Lower pressure
Diaphragm Pumps
The professional choice. Self-priming pumps (like Whale or Shurflo) maintain a constant pressure in the lines. Ideal for showers and hot water systems.
- High pressure
- Needs an accumulator
Tank Strategy: In vs Out
Should your water tanks be inside the van or underslung beneath the chassis? In the UK, this is a decision about space vs winter capability.
Internal Tanks
Freeze-proof and easier to install. However, they take up valuable internal living space.
Underslung Tanks
Maximizes internal space. Requires tank heaters for winter use to prevent freezing.
Filtration: Drink Safe
UV vs Carbon
Don't rely on tank water alone for drinking. We recommend a two-stage filtration system: a 5-micron carbon filter for taste and a UV-C LED sterilizer for bacteria removal.
