How to Make Your Own Water Ram
A water ram is an ancient method used to pump water up to higher levels without the need of electricity. Electricity is a precious resource which is in short supply, by making one of these ram pumps yourself you don't need to use any form of energy other than the energy of the stream itself. Although running a generator would provide more than enough energy to power a simple pump this is using up lots of gas which is also in short supply. The only really free way of pumping water is to use a water ram pump.
A water ram pump is actually very easy to make as long as you have the right tools and materials available. It should be possible to make a water ram pump in under a weekend as long as you spend some time getting to know the plans inside out. A ram pump should be able to deliver around 10% of the total amount of water, but it does this for free without requiring any electricity or fuel. It is possible to buy commercial ram pumps, however it's much more fun to make your own.
Step 1 - Collecting Materials
Collect all of the materials together, as this is a complex project there are quite a few different materials that you will need to find. All of the materials should be available for under $100 and it should continue working forever without the need for any fuel or additional costs.
Step 2 - Cutting the Pipe
Cut the pipe into the right sizes, for the largest PVC pipe you should cut it so that it will make an air vessel chamber which will be used to pressurize air which will provide the water with plenty of energy to be pumped up.
Step 3 - Assembly
All of the pipe pieces need to be assembled together according to the finished plan. Use the primer to clean off the surface of the pipes and prepare them for gluing together. Now use the cement with the brush applicator to glue the 2 sections of pipe together. Repeat this until the air pressure chamber and the whole ram pump is assembled and is starting to take shape.
Use the converters to attach the brass threaded swing check valves onto the pipe. It's important that you choose a solid brass fitting otherwise this will corrode very quickly over time. When screwing in threaded connections use some PTFE tape to stop everything from leaking.
Step 4 - Pressure Gauge
As an optional step a pressure gauge can be fitted if you like, this will help you to work out how much pressure has built up in the air chamber and how powerful it will be. A pressure gauge can also help you to identify any problems which you may be experiencing.
Step 5 - Installing the Pump
Once the pump has been made it's then time to install the pump. The water inlet section of the pipe needs to be submerged under the water. After momentum has built up the water should start to flow out of the top of the pump.
