Hydro-Tank is the ultimate water system for your Off-Road vehicle. Just the flick of a switch and you can have pressurized water. Use it to wash your pup down on a hot day at the beach, put out your camp fire, take a 25 minute shower(depending on options), rinse off your bikes, boards, gear, small children, horses and so much more. The possibilities of Hydro-Tank are endless. So go outside, explore, get dirty, when its time to go home, simply wash away the dirt with your own onboard water system.

                                                       How We Started

The idea of Hydro-Tank started out in the middle of the Anza Borego desert in California. We were out camping with family when we realized we needed more water storage but didn’t have anywhere to put it. After discovering that the rear bumper on a Jeep Wrangler JK was hollow we started designing a kit that would be easy to use and could take advantage of this. After months of testing, developing and countless hours of off-roading throughout California, Arizona, Nevada, Canada, Uganda and Mexico we have developed a DIY kit that functions perfectly every time. We now offer versions for the Jeep Wrangler, Toyota 4Runner and Tacoma


Where are you located?

Hydro-Tank is based out of Fallbrook, California where all of our design, fabrication and assembly is done in-house. We ship anywhere in the US and have even sent kits across the world to Uganda, South Africa and Australia for testing. Please email us for international shipping options.

What if i dont have a factory bumper on my JK

We understand that a lot of people upgrade their factory bumper. Thats why we partnered with RotoPax and offer several versions to meet your needs. We also have Frontrunner tank versions and AEV® rear bumper versions which eleminates the need for their hand pump.

Will this kit void my vehicles warranty?

If installed correctly, Hydro-tank will not void your factory warranty since it does not interfere with the functions of the engine, transmission or suspension.

Why choose Hydro-Tank over other options?

There are 4 main reasons to choose Hydro-Tank.

  1. The Hydro-Tank system is an integrated part of your vehicle. No more angry wife becuse you forgot the portable unit and far less likely to be stolen because it is out of sight.
  2. Hydro-Tank uses a low current electric pump with automatic shutoff. No need to pump up or pressurize the tank which means less chance of a tank rupture over time and consistent pressure until the last drop.
  3. Since Hydro-Tank uses an electric pump it is easier to refill on the go. Simply fill the bumper or RotoPax up and you are read to rock. You can even use the pump to refill from a nearby stream or water source while camping.
  4. Our customer service is out of this world. If you arent happy, we arent happy and we will do whatever we can to make it right.

Will Hydro-Tank drain my battery?

No, The Hydro-Tank pump is a low current pump that uses very little power. If accidentally left on the pump will automatically shut off once pressure has built up. The system can be used with the vehicle running or off.

What kind of Warranty does Hydro-Tank have?

1 year warranty on the entire kit from date of purchase and lifetime bracket warranty. That means, if you bash, smash, break, crack, bend or snap your Hydro-Tank bracket, simply return what's left of it to us and we will send you a new one. No questions asked.

Will you send me instructions on how to install Hydro-Tank?

In an effort to conserve paper, Hydro-Tank does not include printed instructions. If you go to our "Shop" page, you will see a link to download the intructions manual. Simply, click on the pdf symbol. If you would like a printed copy, please leave a comment at checkout and we will gladly provide one.

Does Hydro-Tank work with any charities?

YES. 5% of every kit sold will be donated to a different charity or nature conservation program, every month.

Can you drink from Hydro-Tank?

Yes. Depnding on which option you choose. All of our RotoPax options are safe to drink but we do not recommend drinking water from an original Hydro-Tank which used the plastic rear bumper.
