Why a Reliable Water System Matters in Vanlife
Whether you’re living full-time in your van or heading out on a weekend escape, water is essential. From drinking and cooking to showering and washing dishes, a well-designed water system is one of the backbones of a successful custom van conversion. The right setup keeps you comfortable, hygienic, and prepared—no matter how far off-grid you roam.
At Agile RV, we understand the importance of balancing reliability, space, and functionality when it comes to water systems. Here’s what you need to know when choosing the best system for your custom conversion van.
Key Components of a Vanlife Water System
A basic water system in a conversion van includes a combination of the following components:
1. Fresh Water Tank: Stores clean water for drinking, cooking, and washing. Tank sizes can range from 5 to 40 gallons depending on your needs and available space.
2. Grey Water Tank: Collects waste water from sinks and showers. A properly installed grey water tank helps you stay eco-friendly and compliant with local regulations.
3. Water Pump: Pressurizes the system so water flows easily from your faucets and shower. 12V electric pumps are compact and efficient for van builds.
4. Water Heater: Optional but great for added comfort, especially for hot showers. Options include electric, propane, and engine-connected heaters.
5. Filtration System: Important for ensuring safe drinking water, especially if you fill your tank from campgrounds or natural sources.
Each of these components plays a crucial role in delivering a reliable and convenient vanlife experience.
Assessing Your Water Usage Needs
Before building your water system, think about how much water you’ll use. Do you plan to cook and wash dishes daily? Will you need an indoor or outdoor shower? Are you traveling solo or with a partner?
At Agile RV, we help our clients assess their travel style and water usage needs. A part-time traveler may only need a small system with jerry cans and a simple pump. A full-timer, on the other hand, might benefit from a larger tank, water heater, and fully plumbed sink and shower setup.
Fresh Water Tank Options
Fresh water tanks come in various materials, shapes, and sizes. We recommend food-grade polyethylene tanks for safety and durability. Depending on your van layout, tanks can be installed over the wheel well, under the sink, or beneath the van chassis.
We also offer custom tank options to maximize otherwise unused space in your van build. Easily accessible fill ports make it convenient to replenish water on the road.
Grey Water Management
Managing grey water responsibly is an important part of sustainable vanlife. Agile RV installs grey water tanks with proper venting and drainage systems to prevent odors and leaks.
We also offer external grey water tanks for clients who want to conserve interior space. These systems include easy-to-use drain valves and hose attachments to empty safely at dump stations.
Pumps, Heaters, and Plumbing Essentials
We install high-quality 12V water pumps that are quiet, efficient, and reliable. For heating, our clients can choose from compact electric water heaters or propane options integrated into the van’s main fuel source. All plumbing is professionally routed using food-safe PEX tubing and fittings, ensuring a clean, long-lasting system.
Our builds include thoughtful touches like insulated tubing to prevent freezing, easy-access maintenance panels, and water level indicators so you’re never caught off guard.
Onboard Filtration for Safer Drinking Water
Staying hydrated is critical, and safe drinking water is a must. A filtration system removes particles, bacteria, and unwanted chemicals. We install under-sink carbon or UV systems depending on your budget and travel plans.
We also offer pre-fill filters that attach to your hose during tank fill-ups and compact bottle filters for extra peace of mind.
