In emergency situations you may need to know how to siphon gas out of a tank. In other instances you may need to know how to siphon water. You just never know, that’s why I am adding this skill to SharedSurvivalKnowledge.com
What you need:
Tube or hose (ideally a clear tube works best so you know what is going on, and you don’t end up with a mouth full of liquid)
A bucket, can or other vessel to catch the liquid
How to do it:
Position the bucket lower than the tank you are draining.
Place one end of the hose into the tank as far as possible until you hit the bottom at least.
Start with the dry end of the tube higher than the water source, and suck water into the hose. Fill as much of the hose as you dare with liquid. Even with an opaque hose, you should feel the liquid approaching your mouth and have plenty of time to stop before you get a mouthful.
If you are using a hose that is too long, it will create a problem – an air bubble. To avoid bubbles from forming, keep the hose flat or running up towards your mouth, like a drinking straw.
Maintaining mouth suction on the liquid, crimp the hose or slip your thumb into your mouth over the (lips) end of the hose. You are trying to prevent air from getting back into the hose and ruining your hose-full of liquid.
Next, drop this (lips) end of the hose into your target bucket, gas can or front lawn. Release the crimp (or your thumb) and water should immediately start flowing out of the hose.
A good siphon is quiet. If there is a lot of gurgling and bubbling, you have some air in the hose, which will slow or stop the siphoning. It usually isn’t worth the trouble to re-start a slow siphon unless the water flow has completely stopped.
Once the liquid is flowing, your attention should turn to the wet (source) end of the hose. Keep it submerged. The longer you can keep air from getting in, the more liquid will be removed.
Eventually, air will get pulled in and will interrupt the path of the water, stopping your siphon.
If you follow these easy steps then you should be able to siphon without getting a mouthful of liquid.
