WATERPORT PORTABLE WATER SYSTEMS
WaterPORT DayTank 4-Gallon Pressurized Water Tank
More water. More mounting options. Ready for a full day of adventure.
The WaterPORT DayTank delivers four gallons of portable pressurized water for camping, overlanding, beach days, biking, fishing, work sites and everyday outdoor cleanup.
Connect it to a standard garden hose and the DayTank pressurizes automatically as it fills. Once you're away from home, pressure can be restored through the integrated Schrader valve using a bike pump or portable air compressor—or with the optional WaterPORT Pump Cap.
Mount it to your roof rack, truck bed, trailer or adventure vehicle and enjoy clean, pressurized water whenever and wherever you need it.
THE EVERYDAY ADVENTURE TANK
Enough Water for the Day. Compact Enough for the Daily Driver.
The DayTank sits in the sweet spot of the WaterPORT lineup. It carries twice the water of the GoSpout while remaining compact enough to mount to a wide variety of trucks, SUVs, trailers and rack systems.
It's an ideal choice for anyone who wants more capacity and permanent mounting flexibility without stepping up to a larger expedition-sized water tank.
Portable Water Pressure Without Pumps or Power
Self-Pressurizes While Filling
Connect the included fill valve regulator to a standard garden hose and the DayTank automatically builds pressure as it fills.
Multiple Pressurizing Options
Restore pressure away from home using a bike pump, portable air compressor or the optional WaterPORT Pump Cap.
Five-Pattern Spray Nozzle
Switch between spray patterns for showering, rinsing dishes, cooling down, washing hands or blasting mud from gear.
Eight-Foot Coiled Hose
The included hose gives you useful reach around the vehicle while retracting into a compact footprint for storage.
Quick-Fill Large Cap
The large opening makes the tank easy to fill, drain and clean—and allows you to add ice for refreshingly cool rinses on hot days.
Modular Mounting System
Optional mounting solutions let you secure the DayTank to platform racks, crossbars, truck beds, trailer hitches, roll bars and other adventure setups.
Food-Grade Construction
The tank is manufactured from food-grade, BPA-free polyethylene for carrying clean potable water when properly maintained.
UV-Protected Tank
UV protection helps resist fading and deterioration during regular outdoor use on exposed racks and adventure vehicles.
All-Brass Valves
Durable brass valves and quick-disconnect hose fittings create a reliable connection built for repeated use outdoors.

How the WaterPORT DayTank Works

Repressurize
Add air through the Schrader valve whenever more pressure is required away from home.
PRESSURE YOUR WAY
Three Ways to Keep the Water Flowing
Garden Hose
Fill and automatically pressurize the DayTank before leaving home.
Schrader Valve
Use a standard bike pump or regulated air compressor to add pressure on the road.
Optional Pump Cap
Add convenient hand-pump pressurization without carrying a separate air pump.
Never exceed the manufacturer's maximum operating pressure of 40 PSI.
Mount It Your Way
The DayTank is WaterPORT's most versatile modular tank, with optional mounting systems for a wide range of vehicles and outdoor setups.
Choose the WaterPORT mounting system designed for your vehicle, rack or installation location. Always confirm available space and mounting compatibility before ordering.
