I came up with this when I was house sitting for my parents and the basement started to flood. The original was made with a 5 gallon bucket. I have made two since and found that culligan style water jugs work better. I don't have one currently constructed, I am bored at work and piece this together with MS Paint. hehehe. But you should get the basic idea. This is my first Instructable, I've been reading instructables everyday, and I've been dying to post something. Hope this helps some of you out.
I use this same concept to piggy back 3 shop vacs together to get more suction once. My boss brought his boat out of the water this year with-out pumping out the septic tank. Of course we didn't want to ruin a shop-vac bu pumping sh** into it, and we were told that one shop vac didn't have enough pull. It worked great unfortunately we didn't get any pictures. Happy Sucking!!
Step 1: Materials
The marterials you need include:
1) Vacuum with a hose
2) 5 gallon water jug (Can be a bucket, but this requires more cutting and sealing)
3) Utility Knife (or equivilent)
4) Length of hose, or vacuum tubing
5) Duct Tape
Step 2: Prep
Use your knife to cut a hole in the side of the jug for the hose to be attached to. Make this as close to the outside diameter of the hose as possible. Don't make it too close to the hole that the vacuum will be sucking through, or you will get water in your vacuum, give it at least 6 inches (15-16cm). Put 2-3 wraps of duct tape around the end of the hose so that it fits snugly and plug it into the hole. Now seal this joint the best that you can with more duct tape.
Step 3: Final
Give your vacuum hose enough wraps of duct tape to fit tightly into the main spout of the jug. Plug it into the spout, again, seal this joint with more tape.
That's It start sucking down some water.
