Another nice feature of the Helio Shower is that it is compact. And that’s a good thing when your son is 6’4″. A 7 foot hose is included to insure even a taller than average human has enough hose to reach their head. Periodically pumping the foot pump to maintain pressure throughout your shower. Once the Helio is adequately pressurized, you can enjoy the steady stream of water from the shower for 5-7 minutes. Offering an easy to use foot pump, the Helio Pressure Shower is pressurized by simply stepping on the pump a few times. The Helio Pressure Shower sits safely on the ground and holds 11 liters of water (2.9 Gallons). Secondly, if you’ve ever tried a gravity shower system, the water pressure is nothing to write home about. First, the quantity of water limits the amount of weight you can lift and that a tree branch can support. Several challenges present themselves with these systems. Most camp showers are gravity fed systems that require the user to fill a bladder and hang it in a tree or some other form of elevating it. While spending time in the Porcupine Mountains over Labor Day weekend, the Helio Pressure Shower eased the task of keeping both equipment and personnel clean. Take away running water, sinks, toilets and showers and you’ll see what I mean. As soon as you leave the comfort and convenience of civilized life behind, you’ll realize that several tasks we take for granted are more difficult in the woods.
