I have a 50 gallon water tank in the basement and a solar tank on the roof. The roof tank is 35 ft above the basement tank and the top of the basement tank is connected at the bottom of the roof tank with 1/2 inch Pex with valves. Is there a simple way of pumping the basement water to the empty roof tank. Unfortunately I can't use city water pressure to force the basement water up to the roof. I am trying to transfer the basement water to the roof leaving the basement tank empty.

Use this handy dandy conversion kit and you can add some tank treads to your car! Holy smokes, this is gonna be the best thing ever for dominating the highway. The mileage will take a little bit of a hit, or a lot, but it must be worth it, right? Link

Hi Instructablers, As what mentioned in the topic, I am thinking of transporting water from my leaking pipe back into my tank which is roughly 10m above? Lets not talk about replacing the leaking pipe. Help help help!

I have a 14000 rainwater tank, and like to find a way go clean the debris from the bottom potentially recycling the disturbed water - so there is minium loss i have a ready supply of compressed air near by.,.,. can any one devise perhaps a venturi device that is easy to build, runs on compressed air and effectively vaccuums the muck from the bottom while recycling the caputred water....

If I were to have 2 seperate buckets, one with ground and the other with something like 9 volts nothing would happen because the 2 bodies of water arn't connected. If I were to join the two bodies of water using a wire would electrolysis take place?

I have been browsing through all the fish tank instructables and I thought that they were rather rubbish to be honest.... I want an instructable to build a decent tank in a rectangle shape with the dimensions of Height: 12" Length: 20" Depth:14" (Dimensions do not have to be followed but appreciated if they are and dimensions do not include lid space) If there is also any specific thicknesses needed for the tank to hold the capicity of water this would greatly appreciated if stated. I would also like the person who choses this project to use links to websites for the materials/tools (preferably English GBP currency) Any links to what types of fish are work well together would also be a bonus. Thanks in advance to anyone who will write the instructrable for this.

Through the MIT Club of Northern California, Christy and I got the chance to tour the Military Vehicle Technology Foundation's collection in Portola Valley. Seeing 100 tanks from different time periods lined up and seemingly ready to roll was pretty amazing. I've always had a thing for half-track vehicles, and was especially pleased to see a half-track motorcycle (SdKfz 2 Kleines Kettenkrad). In all honesty, this is probably one of the most impractical vehicles ever created, but it just looks so cool. My other favorites to see in-person were a SCUD missile launcher (SS-1b Scud A) and an M48A5 AVLB (armored vehicle-launched bridge).They also have a large shop where they repair, rebuild, and often re-engineer parts to restore the various tanks. While I was there, they were in the middle of repairing a World War II-era German tank found in a river. The collection is the hobby of Jacques Littlefield, whose father, Edmund Littlefield, amassed a $1.7 billion fortune by running the family construction and mining company, Utah International, and merging it with GE (more here at Forbes).The Instructables forums aren't exactly the best place to few 57 pictures, so here's my Flickr set, and here's the Flickr set of the person who organized the tour.

Hi, I have coffee machine with small water tank. i want to put large water tank next to it so i would not need to refill it every time. my problem is that the water tank in the machine is not sealed, so if i put more water with a hose from bigger tank it will spill out.. How can i create bigger water tank next to it so the smaller tank will refill automatically? Thanks,

There was a similar post to this one a couple of years back, the difference being that both my tanks are filled from separate branches of the same supply using a ball valve in each tank to stop them filling. I then have an outlet from both tanks connected together that then goes off to a pump. One tank is 5000 litres and the other is 3000 litres, currently the larger of the two is redundant and its outlet valve is off, but come the summer i will need to introduce the second tank. I am located in southern Spain and in the summer they turn off the water supply to save water hence the tanks. My question is as the tanks are of a different size, if i were to fit the smaller tanks outlet with a non return valve so that the larger tank can not fill the smaller one via the outlet pipe, would this work i.e. would the joint outlet pipe still feed the pump correctly or would it have more or less pressure. I appreciate that i could balance the two tanks, but i would much rather be able to use all the volume i can. Many thanks.

Alright fellow instructables, here's the lowdown: I'm currently attempting to build a hand-held flamethrower that you only need one hand to use, sort of like a pistol. However, when I was looking at a diagram for a regular Army flamethrower, I realized something: The fuel tanks on the flamethrower werent pressurized, and the fuel was pushed out using a pressurized tank that was fed into the fuel tanks. Now here's my question: Because I'm just trying to make a little hand-held that I DON'T need to shoot 50 feet, can I skip the pressure tanks and just jump to a commercial fuel source, like one of those miniature camper stove fuel tanks? Thanks Outdoors!

I need some advice. I have a great idea that would be amazing if it worked. I want a small scuba/air tank whatever you want to call it (like a scuba secondary tank or a paintball co2 tank) that i can use to mess around with in a pool. I dont want to be constantly breathing, just enough to take a deep breath, go underwater and hold it for a minute, release air from the tank-take a breath, hold it, take another breath from the tank, hold it, and so on. Just enough to get a few breaths and be under water to last me for 5 or 10 minutes. The only thing is i dont want to have to fill it at a dive shop or from a tank that has to be filled at a dive shop like scuba secondary tanks. i want to rig it to fit a bike pump (which probably will not have enough psi to get the amount of air i want) or my air compressor. So i would like advice and also would i need an air regulator since im not constantly breathing? what could i use as a regulator if i need one at all?

I have recently acquired a 25 litre compressor on which the motor was seized so my plan is to replace the motor and pump with a couple of fridge compressors however the tank is more than 10 years old and although I cannot see any damage is their anyway to check it is safe to pressurize to 8 bar? it has 175PSI stamped on it so I assume its designed with that as the maximum working pressure but I want to know if I can get it checked as I don't want to blow myself and my garage apart if it bursts I'm in the UK

I would like to ask a couple of questions about joining two external water storage tanks. The tanks have a capacity of 1,500 litres each and my plan is to connect the two tanks with one inch pvc piping. The domestic water inlet is low pressure (and that's being kind!) but tank A is usually full. My question is will there be enough pressure in tank A to feed water through the one inch pvc piping and into tank B without using a pump? If you consider the water pressure to be high enough to transfer water from one tank to the next, how many tanks could be connected in this way (I am thinking of four tanks)? The outlet from the water pump feeds 9 washing machines in a small launderette. Sorry about the awful drawing. Thanks for any advice in advance.

Oh please help me decide( and more importantly convince my buzz word influenced wife), I want to replace my current hot water heater, there's nothing wrong with the current one other than being 18 years old, meaning it's a ticking time bomb waiting to flood my house. So anyways, the local gas concern has partnered with local contracters Tankless install $25 a month of 60 months, minimum spec heater, does not include expensive, required stainless steel venting. $450 rebate Tank heater 40 gallon install $10 a month sixty months, includes venting $350 rebate Now the no brainer, my gas bill is averaged at $41 a month, $30 is actual gas charges, Now, the tankless claims to save "up to 50%" which is marketing speak for "does not save 50%" but let's say it does, I would save $15 a month, the difference between the cost of the tankless versus the tank, so it would be 54 months before I started saving money. And since we plan on "upgrading" to a new house before five years (when I've graduated), I will never see those savings. Guess I really should get the tank heater, what do you think?

Well I have a friend who is looking into the purchase of a snake, and meanwhile picking out the snake and the heating element isn't the hard part for him (he's looking at a 23 watt 120vac heating pad for it). He was also looking at a thermostat designed for snake tanks, however they want close to $150 for it, and it doesn't even have many features, it's basically a black box with an 3 digit lcd and a programable timer. I know it wouldn't be hard to put something similar together from a pic and a few different parts, however it's been a long few years since I've designed a full schematic of something, let alone look at one. So I was wondering if someone so kind might aid me in making of a schematic so my friend can go order the parts he needs and I can build it for him (don't have a problem assembying circuits from raw schematics, I find it fun). However, there is a couple things he wants out of it. Number one most importantly, he wants it to be able to adjust the output voltage so he doesn't fry his snake (most simple thermostats simply turn on until temperature is reached, then off), no he wants something more dynamic than that. Second, he needs to have an external temperature probe so that he can keep the thermostat outside of the tank whilst keeping a handy eye on the temp and also obviously so that the thermostat knows when to come on (is there a limit to the length of wire you can put on a thermocouple?). Third and last, we need a simple timer circuit that keeps track of the time (what's that involve? a 13mhz crystal and a few other parts?) so that at night the thermostat can change it's "heating schedual", I assume so that it tries to maintain a temperature say 3-4C above the programmed temp. (night mode anyone?) However the thermostat he was looking at buying wanted you to buy a second cord, which connected to an external appliance timer (yes you heard me, a $9 wall timer) so that it knows what time it was. My friend really needs this as he's looking into getting this snake within the month. I appreciate anything anyone has to offer. Thanks guys! -Punkguyta

I was think what was better? a Small tank with a higher pressure? or a large tank with a Lower Pressure? Of coarse if you had a small tank you gun would look better. This is how air rifles work... you break the barrel (push it down) and that push a pump in to a small tank at a high PSI, Thats why its hard to break the barrel. I was also thinking that if you had a Higher PSI in the air resivour it would release quicker?!. What do you think?

The community has a water tank on the top of the hill and a pump about 1/4 mile away, nearly line of site. There is a float in the tank that used to send a signal down a wire to shut down the pump when the tank was full but the wire has since corroded and is no more. They do not want to run another cable. We are thinking that a solar powered radio transmitter at the tank could operate a shut down receiver at the pump. (The pump has AC power but there is no power at the tank.) Anyone have any ideas how to make this work?

I'm trying to make a portable presureized water system for offgrid use. My idea uses 5 feet of 4" Abs pipe with a cap on one end and a threaded clean out to fill the tank. The capped end would have a valve at the bottom to allow a garden hose or etc to be attached, and a small valve stem( tire valve ) to pressurize the tank via bicycle pump. Is it a feasible idea? Would the water be drinkable? Will Abs stand up to constant presure or would it be best to release the presure when not in use? Im thinking 35-40psi would be reasonable with the tank 2/3rds full of water.

I am creating a custom fish tank stand from 2x4s and sheet wood. I plan to paint it black but I ran into 2 problems when I decided I didn't want the hood that came with the tank. 1) The lighting. I have a pretty good history with LEDs so creating the lighting will not be too hard, only real issue I run into is sealing the lamp. I plan to use an acrylic sheet with holes drilled for the white and blue LEDs. White for day and a row of blue for moonlight on a 3 way rocker. I just dont want water to penetrate the holes from the ports for the light to damage the components. 2) The filter. This is where I am at a loss. I plan on making something similar to this: http://tinyurl.com/fishtankdesign But I have no idea how to an external filter rather than one of the regular table top aquarium ones that would not look very pleasing on a nice stand. Any ideas questions comments or concerns please ask.

Some friends and I are looking to make some projects, mainly air powered. We have been looking for an air tank to hold the pressure before we discharge it but have been having problems finding the exact part. I have found lots of the air tanks to fill tires and stuff like that but I need something to hold a good amount of pressure and let it out in one big shot and can be charge with a normal car tire air compressor. -I need to know the exact name this items goes by. (Just "air tank" gives me the tanks for tire inflation) -I need to know a webite or store to purchase them at. (Home Depot or Grainger by any chance?)
Posted by Umbro 11 years ago
Wasn't sure where else to put this, I'm trying to turn an old ambulance into a shop truck and I'd like to use the stock giant O2 tanks on the side as the reservoir for pneumatic tools. How dangerous would it be to rig the compressor head somewhere else in the truck and pipe the air to the tanks? I'd of course include a pressure release valve and some sort of cup to catch moisture since these tanks wouldn't have a bottom valve (though I doubt a full on air dryer would be practical). I was hoping to use flexible tubing to run the air but I doubt that would be safe at tank pressure. Would black iron and pipe tape be enough? Am I setting myself up for a world of hurt? These tanks would be powering pneumatic tools and possibly a media blaster, thanks for any advice, Mac

Hey guys, this is my first time on the forum section of the instructables! Not a bad place to be, really. So here's the thing. I have this old scooter that I've had for as long as I can remember. It was the very first thing I rode that was powered by a motor and my father bought it for me so I could get ready for my first motorcycle (Which was sadly stolen about a year ago :/). Last year, my dad went back to our hometown to visit family and he brought it back with him, but there was one problem. We have no gas tank for it. I have NO idea where it could have gone or why it wasn't brought back. Oh well though. I have this scooter, the same as Wesley666 does. I'm having trouble finding the gas tank on my own. Notice that there is a gas tank that I took from a weed eater just to try it out. But I'm not sure it would work out very well. I mean, look at the size comparison between the two? I also want to keep original parts on this nostalgic machine. Sorry if the pictures are oriented weird, but these are taken with my phone.You can see from the thread posted above there is a picture that shows a blurry close up to the gas tank and I can't really tell what it says. "Something EBR Motor". Long story short I need to get that gas tank, maybe even the gas line that comes with it, in order to get this thing working again. Does anyone know of the brand name of the scooter so I could get the original parts I need?

Hello everyone, I've come here for some help on designing a PVC-based air tank. I'm planning on building a pneumatic cannon that I can charge once and use to fire multiple short bursts of air. To do I decided to have two tanks -one large tank acting as the main tank and a local tank with a much smaller volume fed by the main. My problem is that I want to squeeze out all the air I can from the main tank, and I'm not entirely sure what the best way to do that would be. My current design uses a spring behind a wooden plunger so that as the volume of compressed air drops, the spring can extend and restore the pressure. (Image attached for clarity) Can anyone spot potential problem areas or places that could be improved?

For the Age of Aquariums Contest we are bringing in a special expert judge, Alex Andon! Alex studied marine biology at Duke and was always fascinated by the jellyfish exhibits at public aquariums. Jellyfish can't go in a regular fish tank because they would get sucked into the filtration system. They require a kreisel tank with a special water flow pattern to keep them suspended in the middle of the tank. There were no commercially available jellyfish tanks, so Alex started experimenting with large tanks and then made them smaller and more affordable until he had designed the first desktop jellyfish tank. He launched it on Kickstarter and raised $163,000, making it one of the first successful crowdfunded launches of a product. The company sells specialized jellyfish aquariums and breeds its own jellyfish, shipping them overnight to customers throughout the U.S. Alex's latest project is the Chargerito, the world's smallest in-wall phone charger.
