Fire Extinguisher to Water Mod

I added a valve stem to a fire extinguisher. To refill it, you unscrew the top then pressurize it with a bicycle pump. The valve stem came from Auto-Zone.

The wind knocking over the cups THEN the blast had me laughing out loud. Nice work.

We did this in high school (1985). And drove around soaking people with it. There were those who appreciated it, but most didn’t 😁

Nice idea but you have to make sure the extinguisher is aluminum and not steel like this one is because over time the cylinder rusts inside and irritates skin if sprayed at people and soon it will not be able to hold pressure. I made the same mistake and now mine won’t hold pressure for more than 2 minutes. If you are going to do this to spray people, make sure it is aluminum by sticking a magnet to it. If it doesn’t stick, it’s aluminum and you can safely use it as a water gun. Try the kidde pro extinguisher. Those are aluminum and cheap.

Need to relabel the container so someone who doesn't know it's a water only extinguisher won't use it unsafely. You have made an ABC extinguisher into an A. Good idea, just needs that final touch

[@gerardjohnson2106]

Portable bidet. Do not use high pressure. :-)

[@theblueexitsign8249]

All fun and games until the cylinder rusts inside and you get rust water spraying out of that thing up no mans land lol

[@stevenbarton5179]

good video.did he use a foot pump? 100psi good pressure i have a dunlop major foot pump hits 150 psi great for pressuring my 9 ltr extinguisher life savers every home should have one.

1:00 any instructions on how to tie that knot?pls help me out

[@alphacapo]

All that.... For that. Lol

[@Fredengle]

any way did you find this ok with only 100 PSI?

[@tjohnson4062]

Possible to make it to sand blast?

[@googleuser868]

Looks like a good start on a booby trap. Just need some trip wire and linkage to pull the trigger. Something stronger than water inside. Maybe a bright colored dye or a chemical of some sort. Battery acid?

pepper spray!!

My buddy has one of these he fills with tequila

Hiya mate. I have refilled 2 fire extinguishers. Both water. When I refill to an appropriate level of water I screw the top back on as tight as human hands possibly and when I recharge them the air goes inside the bottle but the pressure gauge doesn’t go up. I am using a hand pump tho. But I can’t figure out why the gauge isn’t moving. Any idea why?

[@First_Class_Amateur]

I would try placing the fire extinguishers in water as you pump them up. Maybe the seals are bad.

[@JC09_lvp]

@@First_Class_Amateur will try that thanks

[@WitchidWitchid]

Very clever. I used to experiment with stuff like that during my young years. And now too. :) Only thing, if you are going to put it where others may have access to it make sure you put a label that says "CLASS A FIRES ONLY". Else someone may spritz it onto an electric or flammabble liguid fire.... I have thought of repressurizing a water can extinguisher (oil) with a bike pump but I didn't know if there would be enough pressure to reach 100psi with the bike pump.. Now I know there is enough pressure. So if I get a water extinguisher I should be able to keep it charged from home.

I got an old water version myself and they are amazing, 50 feet of water for 50 seconds, I originally took mine down to the tire shop and they let me use their compressor, needed 125psi and at the time I didn't have a compressor that big.

[@WitchidWitchid]

​@@shanek6582 I use a relatively small inexpensive air compressior / tire inflator that I bought brand new off Ebay for around $40-$45 bucks. It operates off of 110 VAC and is rated up to to 130 psi air pressure. It pressurized the extinguisher well up into the operating range of 100psi with no problem. The only drawback is that the pump is low volume so it takes a bit of time to pump the extinguisher up 10 100psi.

[@shanek6582]

@@WitchidWitchid betting than hand pumping! Thanks man

[@josh9399]

ha awesome!

[@jimyoung7090]

Uhm? Why not shake the tube out in the trash can instead of on the workbench. Then sweeping it into the dust pan and dumping it in the trash? Just wondering. Jim Y P.S. Thanks for the video, I've been wanting something like this for a while.

[@TotoGuy-Original]

wow all that effort to open it i opened mine by hand and thighs held the extinguisher with 1 hand between my thighs too and then used the other hand to undo it. took some effort but it wasnt too difficult. it was brand new as well until i emptied it

[@FelixTsigel]

The main ingredient in the powder is soda. I use it for cleaning dishes.
