The Day Tank™ takes the hassle out of manually pressurizing water by conveniently absorbing the water pressure from your house. Simply plug your garden hose into the tank’s quick-connect and your Day Tank will automatically pressurize as it fills.

Take pressurized water wherever you need it with Day Tank. 3.85 gallons of water available to you wherever you need to clean, rinse, refresh, or just water something down. Add pressure as you fill it with a standard garden hose, or use the optional Pump Cap to pump it up while on the road. You can even connect a bike pump, or air compressor to the included Schraeder valve to add up to 40psi.


Our multi-pattern nozzle turns your pressurized water into a swiss army knife. Use the mist spray for hot days on the boat, jet rinse to spray the mud from your tires, shower setting for getting the salt off your skin, or center spray for cleaning dishes on the go. Life is full of messy situations, we have you covered.

Fresh Water

All of our tanks are made from food-grade plastic that is BPA-free. So fill it up with drinking water if you want!

Mounting Options

The Day Tank has 4 available mounting options: hitch mount, bar mount, platform mount, and bed rail mount. These mounting options allow you to mount to virtually anything you can think of: roof baskets, trailer hitches, ATV bars, RV ladders, boat railings, truck beds, roll bars, airboats, bike mounts…the list goes on!

Absolutely dope.

Hella quick delivery to California. Easy af to mount to pretty much any location. Came with some extra fittings just in case. Can’t beat pressurized water after playing in the dirt.

Portable water tank

Awesome product! I use it to wash myself and family off from a day at the beach before getting back into the Taco. Only issue I had was my low profile bed cover goes over my bed rails so had to C-notch it’s metal frame for the drop down plate. And it didn’t come with the bracket to attach the nozzle to the tank. I guess the fore got to place it in the box. But all in all amazing product! 🤙🏻
