Bike pump problem?

I was using my bike pump today to fill a pneumatic launcher, and finally I just got fed up with the leaking around the pump base. On every stroke, the first 3/4 of air would be leaked out of the base, and it would only compress the remaining 1/4 of air remaining, and that would only compress if you pushed down very hard, and quickly, otherwise it all leaked out. And no matter what pressure the launcher was pressureized to, the pump handle/piston would slide down slowly, getting pushed down under it's own weight, meaning that there was almost no resistance to it. I think the leak is occuring where the tube meets the pump base, and you can feel air rush out with your legs as you pump. I'm pretty sure there is a one way valve in the gauge portion of the pump, which connects to the base with a hose,  and the filling hose is coming out of it, which is allowing me to compress at least a little air before the rest leaks out. I disassembled  the pump, starting with the base. Turns out, the leak was from an oring on the tube which was not tightened down enough by a screw on ring around the base of the tube. Put it back together, and voila, pushing my finger against the schrader valve connector and pushing down on the pump handle created pressure against my finger and no leaking. As soon as I hooked it up to my launcher, i realized something was up, I could pump down once, but the pump handle just got pushed upwards as soon as i let go. This is what I can't figure out how to fix. It seems the one way valve in the gauge portion is locked in the open position. Anybody know how to fix this? EDIT: Okay I took pictures of the pieces. I now cannot figure out if the valve is in the base, or the gauge portion, so i have included pics of both. Hopefully someone can help me figure this out. EDIT 2: Turns out the valve is in the base, and the ball just fell out when i first disassembled it, i have now found the ball and it is working fine.

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!

Vacuum pump voltage?

Today I was dumpster diving and i found an old vacuum so i decided to take the pump out but i made the mistake of not checking what voltage the vacuum runs on, because it also had a spinning component at the mouth of the vacuum. I think the pump works fine because i noticed that tube connecting the mouth of the vacuum and the pump was broke. Is there anyway to find out what voltage it runs on? would standard 120 be ok?The markings on it say 81 b-9 ECP 6500-240 HPU+ 60hz HD10 120 vac 07:07 does that mean it will work off a standard 120 outlet?update: What I am going to do with this motor has been decided. I will be attaching it to the back wheel of my bike with a car battery, i will install some type of switch on the handlebar or add something like a dimmer switch, this would allow me to have the motor on if i want, and i can adjust the speed.

Advice on A centrifugal pump.

Hello, I recently was given a pet from a friend and after doing some research on what the little guy needs I came to the understanding that the current enclosure he is in is inadequate for his needs. Therefore, I wanted to save up some cash to get him the right size tank set up that I know he deserves. In the meantime though, I have plenty of things laying around the house that I feel could render him a more comfortable habitat till that investment goes through. After more research on the matter, I came to find that for most household aquariums, the bulk of the work falls on your filtration system. That being said, I wanted to go for a Wet / Dry Sump Filter setup as it would be  the most easiest system to setup at home with the various resources laying about. Unfortunately while gravity will be doing the work of siphoning the water from the tank down to the Wet / Dry Filter Media, it will not be moving it back up to the tank. For that I concluded there was no escaping the need of a pump in some shape or form to move that cleaner water back into the tank. From what I read the pump will pretty much determine how big I can make his tank.  So this brings me to my current dilemma. Presented with various motors around the house, I went for the biggest I could find (* excluding the water pumps in our cars mind you). That so happen to be a 1.25 HP Wet & Dry Shop vac that was collecting dust in the garage. I confirmed the motor is working and already came with the impeller attached to it. I was hoping to see if you fine folks could share some wisdom on how I can: 1.) Make it Waterproof. 2.) Adhere the right type of casing around the Impeller and Motor so as to benefit from the  Bernoulli's principle and get the most water moving through my system.  3.) I intend to have this setup not 15~20 feet from where I sleep, this motor is LOUD. I was reading online about creating a sound damping box for it and was wondering what suggestions you guys might have for that? I keep fearing there won't be enough ventilation and it will over heat. ....anything else you would like to throw in. TL;DR :

Tired of dumping dehumidifier... Float switch, submersible pump, and a timer?

I have a small dehumidifier with a removable tank that has to be emptied far too often.   It has an integrated float switch in the tank that shuts down once full, but if you neglect to dump it, the basement gets way too muggy. I would like to put in a submersible pump (like this) that is activated by a simple mechanical float switch.  Once activated, I only want the pump to run for a set amount of time, in order to keep the pump from pumping all the water out and running the pump dry.  I thought about this timer, which has a minimum interval of one minute.  One to two minutes of pumping would be about right for the tank size, depending on the pump flow rate and where the float switch was set to initiate the pump. I had originally looked at a Kerick Valve float switch, but this will only let enough water drain out to lower the float and close the valve.  This will essentially just trickle out. Any ideas on this? I don't want to drill a hole in the tank and just run a drain tube... though I considered it.  Part of the reason is that I wanted to avoid just letting it trickle out.  And I also felt like I wanted to tinker just a little.  :)

How to Clean Silt from Dug Round Water Wells Used by 3-4 Billion People on Planet?

This is a clam shell bucket, from an old toy crane. I am taking this to a machine shop, welder, had having them make it 18 inches wide. It would be used only with rope, no block and tackle.  Problem: As best I can surmise, about 1-10 percent of hand dug, round water wells used by around 4 billion people on the planet are full of silt, dirty, and old plastic jugs used to pull the water up from well. As the silt rises in the well, the wells slowly become too dirty, or the locals need to pull the water out in buckets, then allow the silt water to settle. It is way to expensive for people who earn 10 USD per day to pay people with pumps to drain the wells. I want to create a 1-2 man powered clamshell bucket system to clean these wells.  What is the best way to make a method to clean a dug well? How much would the steel, rebar cost? Labor is 10 dollars per day in central American, South America, Africa etc. Thanks for help, I will take the finished bucket to Lome, Togo West Africa to test, and modify, iterate.

Concept for Pump + Bolt Action

I had this idea for awhile. Basically you combine the pumping action of a pump and the loading action of a bolt action to get something with a high RoF and high power without needing a turret. The idea is quite simple really. My idea is to have a bolt loading pin attached to a pump that contains the magazine. when you pull the magazine back far enough it will load a round into the chamber. When you move the pump back the bolt pin will push the piece of ammo forward with it. Anyone feel up to making something like this?

new knex pump action

Please try to make it off of my crude drawing. If you post an ible please give me credit or tell me if it has been done. If so post link. The way it works is when you pump it the pusher hits the top most ammo. That pushes it onto the ammo lifter. When you pump forward  that pulls the string which raises the ammo lifter. That then becomes part of the bottom of the barrel. Then you cock the gun and fire. Repeat. P.S. The scriblls on the paper are not hyroglfics they are words.
