Most Common Questions in This Category
How much water storage do I need?
Most people carry 50–100L for fresh water. Depends on your usage (showers? dishwashing?) and refill frequency.
Should I install water tanks inside or outside the van?
Inside = protected from freezing. Underslung = saves space.
How do I stop my water freezing in winter?
Insulate pipes/tanks, use internal tanks where possible, and drain system before hard frost.
What kind of water pump should I use?
12V diaphragm pumps (e.g. Shurflo) are the most popular. Submersible pumps are great for simplicity and low power.
Do I need an accumulator tank?
Recommended with 12V pumps – it reduces cycling and improves pressure consistency.
Can I drink water from my tanks?
Yes – but install a proper filter (if living somewhere where drinking water is questionable). Carbon filters or UV systems work best for full-timers.
How do I fill the water tanks easily?
Use a fill port on the outside of the van or a quick-connect hose setup. Always carry a collapsible hose.
Where does the wastewater go?
Grey water goes into a separate tank. You can use a portable container or install an underslung tank. Some people install a y-valve to optionally drain water directly outside the van.
Do I need a hot water system?
Only if you want hot showers or washing up. Options include LPG boilers, 12V immersion heaters, or heat exchangers.
Can I install a shower in a small van?
Yes – consider outdoor showers, flexible hoses, or collapsible indoor cubicles.
What plumbing fittings should I use?
John Guest push-fit fittings are reliable and easy to use.
How do I secure the water tanks in place?
Use steel brackets or heavy-duty ratchet straps. Ensure they’re mounted low and evenly supported.
Can I use a garden hose for plumbing?
No. Use food-safe pipes for anything going to your drinking supply.
Should I bother with a water level gauge?
Nice to have, not essential.
Perfect! Thank you :)
