## How do you size a fountain pump?

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.

## How many GPH do you need for a fountain?

The rule of thumb, depending on just how much water you want coming out of the fountain, is 100 GPH per one inch diameter of fountain outlet.

## How do I choose a pump size?

Use the pump flowrate calculation: Divide the container volume by the length of time it took to fill up to get the flow rate. 5 gallons / 1 minute = 5 gallons per minute. 5 gallons /30 seconds (0.5 minutes) = 10 gallons per minute.

## How do I know what size pump I need for my water feature?

A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. For example, a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond. You don’t have to refer to a fountain pump size chart to figure out the best water pumps for your garden.

## How do I choose the right water pump?

The most important factors to consider when sizing a water pump come down to GPM/PSI ratings, inlet/outlet size for water and hoses, how high you’ll need to pump the water (measured in vertical feet), referred to as total head lift, and how far you’ll need to pump the water horizontally.

## Which pump is used for fountain?

Fountain pumps are typically centrifugal pumps, which move water using pressure from centrifugal force created by the movement of an impeller. A fountain pump functions like a sump pump, except that the water is fed back into the pond or reservoir rather than out of it.

## What size pump do you need for a water fountain?

To figure out the volume of a pond or fountain in gallons, multiply its length by width by average depth (all in feet) by 7.5. For a 300-gallon water feature of a type (explained below) that requires water circulation every two hours, you’d look for a pump with a flow rate of 150 GPH.

## How are fountains powered?

Until the late 19th century most fountains operated by gravity, and needed a source of water higher than the fountain, such as a reservoir or aqueduct, to make the water flow or jet into the air. Mechanical pumps replaced gravity and allowed fountains to recycle water and to force it high into the air.

## Which pump is used for waterfall?

For example: if the Waterfall is 18 inches wide, an 1800 gallon per hour pump is suited nicely. For a gentler Waterfall, use a 900-1800 gallon per hour Pump and for a more aggressive flow use a 2400-3600 gph Pump. These numbers can be adjusted for any waterfall size.

## Should I turn off my waterfall at night?

Shutting off the waterfall will make the water quiet and still, which means there won’t be as many water molecules circulating and connecting with air that is rich in oxygen near the surface. Moving water is a necessity for every pond or water garden whether it is natural or manmade.

## How long can a water pump run continuously?

Generally, sump pumps can run for six to 24 hours continuously, depending on how heavy the rainfall is and the quality of your pump. The aftermath of torrential rains or even flooding puts a higher demand on your sump pump to keep your home’s low areas dry.

## Should water features run continuously?

Water fountain pumps are meant to run 24/7. It is harder on the pump if it is turned on and off continuously. You should not need to turn your fountain off as long as there is enough water in the fountain for the allotted time.
