There are two critical elements to the art of siphoning. 1. Get water going through the hose from the faucet to outside. This is done w/ the aid of your SiphonAid. However you have to do it for your particular faucet – get some faucet water running to the outside. 2. Don’t lose your hydrostatic pressure. In the SiphonAid video we see how fast the water runs out of the straw when the finger is removed. To avoid losing your hydrostatic pressure – keep a few feet of hose in the bottom of the bathtub. When you are ready to quickly move the SiphonAid to the bottom of the bathtub (you’ll know because you have water on the ground outside) the extra few feet of hose with water in it in the bottom of the bathtub – is that “finger” holding the downside water in the hose. The fraction of a second it takes to thrust the SiphonAid end of hose into the tub water will not disrupt the siphon action.
