Also asked, what is the maximum height water can be pumped?

The **maximum** theoretical suction **height** of the **water**, at sea level, is about 10.33 meters. in practice we consider the NPSH of the **pump** and the pressure losses due to fluid flow. The practical **maximum** suction **height** is located around 7 meters at ambient temperature.

Subsequently, question is, how high can a 1/2 HP pump push water? A two-line jet **pump can** typically raise **water** from depths of 30-feet to 80-feet, and at **water** delivery rates of 4 gpm (gallons per minute) (for a **1/2 hp** 2-line jet **pump** serving an 80 foot deep well) to 16 gpm (for a 1 **hp** 2-line jet **pump** serving a 30 foot deep well).

Also know, how deep can a pump lift water?

The shallow well jet **pumps** draw **water** from one line situated in wells no **deeper** than a maximum of 25 feet **deep**. **Deep** well jet **pumps** use two lines, one for pulling the **water**, and one for pushing the **water** into the delivery system. **Deep** well jet **pumps can pump water** from wells that range from 25 to 110 feet **deep**.

How do I know what size water pump I need?

Measure the diameter of the fountain spout with a tape measure. You will be calculating the gallons per hour, or GPH, by multiplying the diameter by 100. For example, if your fountain spout is 1 inch in diameter: 1 x 100 = 100 GPH, your **pump** will **need** to be rated at 100 GPH.
