Vacuum to Wet-Vac





Introduction: Vacuum to Wet-Vac

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.

    I love this site. I was looking for a way to rig my own wet filter on my shopvac. Now I'll just do something like this. Thanks!!

    I followed this exactly and it works awesome. I have a shop-vac but don't like how I have to take the thing apart, and then let everything dry out for a few days afterwards.

    This is so nice, easy, quick and works with our more powerful vacuum to clean up spills and stains.

    Thanks for the instructable!

    You use the household vacuum cleaner and let your spouse discover that it's saturated with water and rusting inside? Hahaha!

    Regardless of whether the vacuum cleaner is a household unit or a shop vacuum, they need to be disassembled and dried out when used as a wet vac.

    Why use the "good one"? People throw away vacuums all the time, for a broken belt, or when they find out how much the filters cost. Pet owners DESTROY vacuums and throw them away even when the motors are still good. You can source these motors for Instructables projects, and you can clean out the cat-dander vacuums enough to serve as power-heads for a shop vac like this.

    That's pretty cool. If you find an older vacuum with the detachable hose and crevice tool, you could cut down the crevice tool (or wand extension) and epoxy it to a water jug, so that you could instantly connect or disconnect the vacuum hose.

    You might warn people to use a GFCI protected outlet for this, and make sure that the user has a way to shut off the vacuum or disconnect hose before the jug overfills.

    Duct tape is overrated. Try some Gorilla Tape. It can withstand getting wet much better than duct tape.

    Can this be used as a leaf vacume.

    You can use a 25 or 30 litre home brew or chemical drum with the tap fitted for easy empty. But very smart idea in the first place simple, modifiable and obviously workable. The bigger or stronger the vac power the bigger your water catcher can be. For example a 1.5 hp vac motor can handle a 40 litre tank.

    We needed a solution to clean the dirt out of our pond and this works like a bomb BUT the jug fills up too quickly - HELP! Do you think it would work to drill a small hole at the bottom and hook up a hose through which the water could drain?

    you could just hook up 2 or 3 of these in series?
