Choosing a well hand pump for emergency use is actually quite tricky since you need to consider many things. There are so many types of hand pumps available today that you can’t really just make a random choice and hope for the best. To get the best performance, you need to do quite a bit of research and based your purchase to your specific needs. Here are the things you need to consider when determining the size of the hand pump you need:
- Well depth
- Static water level of your well
- Depth of the water in your pipe
- Size of your well casing
Once you have determined these things, you can now determine the right size of well hand pump for you.
Shallow wells, where the static water level is less then 25 feet will require a basic pump. Shallow well pump works great on suction and a basic pump is good enough for it.
For deep wells, you will need a deep well hand pump. Deep well hand pump works using a different principle. This kind of pump pump the water up on a pumping type using a piston valve. This system is then placed below the static water level, right at the well casing. For deep wells, the foot and piston valve are placed 20 to 25 feet below the static water level. The reason for this is it allows adequate water supply in the casing pipe for use. If not done properly, the pump would have very little water to draw and that will be inefficient.
Materials used in hand pumps
The most common materials used in hand pumps are cast iron and other types of metals. Most hand pumps are imported from India, Thailand and China. Most pumps have old and classic designs that is very popular among users. They are mostly used as garden decorations as well because of their appearance.
Deep well pumps are mostly constructed from cast iron and welded steel to avoid rusting. The piping that goes below ground is made of PVC piping which is used for the pump casing. The cost of the whole setup depends on the static water level of the well and the complexity of the well.
A water well hand pump for emergency use is a great tool especially for people living in areas prone to natural disasters like hurricanes and thunderstorms. In emergency case, electricity will usually go out and you can’t use your water well pump until it goes back. This is a great dilemma for many people but can easily be solved by getting a water well hand pump.
