Step 42: Final thoughts
A few final thoughts:
- The hose that drains from the top to the bottom barrel would benefit from being wider. Water can only pass through as fast as the smallest opening can handle. If I were to re-do it, I'd try to drill or cut a wider hole to accept wider fittings and tubing.
- There is most likely a way to pressurize the system with an air compressor for applications that need more pressure than gravity such as sprinkler systems.
- The bottom barrel would most likely benefit from a small hole drilled above the water line to let out air as it gets replaced with water. This will allow the top barrel to drain into the bottom barrel faster and at a more steady rate.
