Pumping water from an underground tank requires a surface pressure pump located above the tank that sucks the water upwards.
Utilizing a Surface Pressure Pump
A key element in pumping water from an underground tank is the surface pressure pump. This pump is positioned on the ground above the tank, and it operates by creating suction to draw the water up through a pipe. Here's a closer look at the process:
- Pump Location: The pump sits outside of the tank, on the ground above it.
- Suction Mechanism: The pump generates a vacuum to pull water from the tank.
- Pipe Configuration:
- Use only one pipe going from the tank to the pump.
- Use only one elbow in the piping; do not use a T-piece.
- Avoiding Air Bubbles: Using a T-piece is discouraged because it can trap air bubbles, causing issues with the pump’s effectiveness.
Optimizing Your System for Efficiency
Here is a summary of the key considerations to make your pump system the most efficient:
| Element | Specification | Why it's important |
|---|---|---|
| Pump | Surface Pressure | Positioned above the tank for accessibility, uses suction to draw water. |
| Piping | One Pipe, one elbow | Minimal connections reduce risk of air entrapment and improve flow. |
| Elbow | Instead of T-piece | Elbows direct water smoothly, unlike T-pieces which create places for air to get caught and impede flow. |
By following these guidelines, you can effectively pump water from an underground tank.
