|Well Hand Pumps|
This article is for those of you dealing with wells. If your water source is a spring or creek, you do not have to worry about these issues. A well has the unique challenge of somehow pulling water up from a deep and skinny hole in the ground. And doing that can become very interesting if you do not have electricity.
We try to focus on good, long-term solutions. This is particularly true when it comes to such an important necessity of life as water. And so most of our articles here focus on exactly that--setting up a water system that will enable you to have a good supply of running water in your home without that system being dependent on the power grid or any other utilities.
But we do realize that some of us might find ourselves in unexpected situations at a time when we may not be able to set up an excellent water system. In such a situation, being able to improvise and set up a make-shift system that will enable you to get water out of a well could be a life-saving skill. Although it would be far better to set up a good system if possible, it never hurts to have the knowledge of how to develop a quick and easy emergency method for getting water out of a well. And even if you do have an excellent water system set up for your well, it is very wise to have a back up. Things can go wrong. Something can break. Your submersible pump can fail. Your alternative energy system could go down. This is why we must have a back-up method of pumping water from our well. And that is what this article is all about.
The "well bucket"
Starting with the simplest and least expensive possible solution. You may be familiar with a "well bucket". It is basically a 3-5 foot pipe (usually +- 4 inches in diameter) with a check valve in the bottom and rope tied to the top. You let the well bucket down the casing in your well using the rope. When the bottom of the bucket hits water, the check valve open, allowing water to enter the bucket. Once the bucket has enough water in it, the bucket may be pulled up the well to the surface. As this happens, the check valve closes, thus keeping the water in the bucket. Once out of the well, the water may be poured into a bucket and carried to your home or wherever you need it.
The well bucket is usually made out of PVC pipe, the check valve may be located at a hardware store or super store such as Home Depot, etc. Be sure to find a flapper type check valve. Ordinary check valves require a certain amount of pressure to open them and the amount of pressure exerted from the bucket resting on the water in the well may not be enough to open some of these standard valves. But a flapper type check valve is very light weight and requires very little pressure to open. You can make your own very easily, but commercial versions of the well bucket may be found. One source is Lehman's .
You see, right now, if your well is in use, it has an electric pump of some sort in it. Unless it is a very shallow well, it probably has a submersible pump that sits near the bottom of the well and pushes water up through a pipe to almost the top of the well. Before it reaches the top, though, this pipe turns 90 degrees, exits the casing, and heads toward your home underground. The reason it exits the well several feet underground is so that the pipe will not freeze. Depending on your climate, there will be guidelines for how deep water pipes must be buried. At that depth, the water pipe coming up from the submersible pump exits the well and heads toward your home underground. Now here is the problem. It is highly unlikely that a well bucket will be able to slide past all of the pipe and electrical wires coming up from the submersible pump. So, in order to use your well bucket, the pump would have to be pulled out of the well. And if you have ever pulled a submersible pump before, you realize that it can be quite a job, perhaps even requiring some sort of mechanical device to hoist it (such as a boom or you could fabricate a tripod above the well and use a come-along). Then the pipe has to be cut or unscrewed (depending on what type of pipe) every so many feet so that you have manageable sections to deal with. Needless to say, it can be a big job if heavy pipe is used, and/or it is a deep well. Are there any solutions that don't require pulling the existing pump? Yes...
The Stalwart emergency hand water pump
This emergency hand pump is a possible solution to this dilemma. It is less expensive than a full-fledged hand pump, but yet it is touted as being fairly easy to operate and can work with static water levels down to 170 feet (supposedly). And best of all, it fits right along side all the pipe and wire in your well, meaning you don't have to pull anything to install or use this hand pump. It is fairly rudimentary, so don't think we are talking about a full-sized, real hand pump, but this could have its place. Here is the website for more info. Lehman's also carries this pump and their current price is less.
Home-made emergency hand pump
If your static water level is fairly shallow, you could even make your own emergency hand pump. Basically, in its simplest, most rudimentary form, this is a small PVC pipe with a foot valve (a one-way valve that allows water into the pipe but will not let it back out) on the bottom. The length of the pipe would be several feet longer than the depth to your static water level. All you do is let the pipe into the well and once the bottom reaches the water level, you forcefully push down on the pipe and pull up. And then you push down and pull up...and then you push down and pull up...and keep doing that until water starts coming out of the top of the pipe. When you forcefully push down, the foot valve allows water into the pipe. Then when you life the pipe it closes, keeping all of that water in the pipe. When you push down again, it allows evens more water in the pipe, raising the water level inside the pipe. As you continue doing this, the water level keep raising until water starts flowing out the top of the pipe, where there is a garden hose connected that allows the water to flow into a bucket. Click here for a sketch of the different parts required and where they go.
A much better emergency backup would be a full-fledged hand pump such as systems carried by Lehman's , Monitor hand pumps (made by Baker Mfg.), and the Bison hand pump . These hand pumps fit along side your current pipe and wire, meaning that you would not have to pull your current submersible pump in order to install or use them. It is simply a necessity that every well have a backup hand pump! Even if you have and independent system using an efficient submersible pump powered by solar panels or an alternative energy system. Every well needs a hand pump! And if your static water level is not terribly deep, your hand pump may even be able to not only push water out of the well, but also on up to a cistern where it can gravity flow into your home. This, of course depends on which pump you use, how deep your static water level is, and how high your cistern is above the well.
