Pumping Water From Basement To Roof

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.

Instructable wanted "How to build a Fish Tank"

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.

Circulating pump with thermostat

I have a 1550 gallon water holding tank and plumbing in an outshed in Fairbanks, Alaska. The pump and pressure tank are also in the outshed heated with an electric heater. To save energy I'm thinking to install a circulating pump inside the tank that circulates through the plumbing inside the outshed to keep it from freezing but not necessarily to the portion of water pipe going under ground to the crawlspace of the house. It should also have a thermostat to start heating when the temp of the water gets to 32 degrees or so. Is there any such thing and if so, how would it be installed? Thanks!

What type of tank should I build? Answered

I am planning to build a ~2:5 scale tank using this video as a guide. I am trying to decide whether to build the base as electric or gas powered like he does in the video. Electric may be less powerful but it is easier to assemble. (for me at least) I may even make an Instructable on it when I get the time. Any suggestions would be welcome. Although I have pretty much settled on a modern M1A1 Abrams-style design for the shell, my mind could be changed.

How do i plug a leak on the bottom of my 5,000 gallon well water tank? Help!? Answered

I can patch the side leaks on me metal tank easy enough with marine epoxy. but there's no way i can crawl in the tank without destroying the bottom with my weight. i would like to find something i can pour in there that would sink and find the hole and cover it up. wouldn't take much with the water pressing against it. maybe some sort of saw dust? it would eventually sink and find the leak? but it can't rot over time or have bad chemicals in it...  or something made of much smaller particles? really needs to be a remedy tested by time, maybe something from our grandfather's day. or, i could make a remote controlled robot with manipulators and a camera! nahhhhhh..... thanks

Tour of the Largest Private Collection of Military Vehicles

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.

Connecting Two Water Storage Tanks

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.

Handheld Flamer- No pressure tank?

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!

DIY Scuba Tank (breath underwater)

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
