**Title:** Building a Ram Pump (No Electricity Required)
**Summary:**
* Introduction to M4 Tech's DIY project: creating a Ram Pump that works without electricity or a motor.
* **Materials listed** (e.g., 1-inch PVC pipes, T-joint, ball valve, check valves, hose collars, etc.).
* **Step-by-step assembly** of the Ram Pump described, with key points highlighted (e.g., ensuring air-tight seals, proper valve orientation).
* **Testing the pump** using a water barrel, demonstrating its functionality without external power.
* **Key takeaways**:
+ Pump should be placed below the water tank.
+ Water output needs a downward path.
* **Working principle explained**: pressure creation through valve opening/closing, allowing water to flow upwards.
* **Pump efficiency**: 10% (only 10% of water passing through is pumped out).
* **Historical context**: invention by John Whitehurst (1772) and largest Ram Pump in the UK (1800 liters/minute, 150m high).
* **Conclusion**: invitation for feedback, with links to more content.
Here are the key facts extracted from the text, numbered and in short sentences:
**Materials and Components**
1. The project requires 1-inch PVC pipes, 13cm in length.
2. Needed components include: 1-inch T-joint, 1-inch 2 FTA, 3 MTA (1-inch), 1-inch ball valve, 1-inch metal check valve (x2), hose collars, and a 1-inch elbow.
**Assembly and Construction**
3. The PVC pipes are attached to the 3 sides of the T-joint.
4. An MTA is fixed on top of the T-joint.
5. A check valve is connected with the arrow pointing upwards.
6. Additional MTAs, PVC pipes, and valves are connected as per the instructions.
**Testing and Functionality**
7. Water is needed to test the pump, filled from a barrel.
8. A hose connects the barrel to the ram pump.
9. The pump is activated by opening a valve and tapping it a few times.
10. Once started, the water rises and flows out through another valve.
11. The pump works without an external power source or machine.
**Usage and Placement**
12. The pump should be placed below the water tank.
13. The pumped water should be able to flow out freely.
**Working Principle**
14. Opening the valve allows water to try to exit, opening and closing the check valve.
15. The closing of the check valve creates pressure, making water flow upwards.
16. The water is stored in a chamber and flows out through the outlet hose.
**Efficiency and History**
17. The efficiency of the ram pump is approximately 10%.
18. Only 10% of the water passing through the pump is utilized.
19. The ram pump was invented in 1772 by John Whitehurst from the UK.
20. The patent was taken in 1809 by Joseph.
21. The largest ram pump in the world is in the UK, pumping 1800 liters per minute to a height of 150m.
