## How do I know what size pool pump I need?

Determine how many gallons you need to pump per hour to clean all the water in your pool in eight hours. Divide the gallons of water your pool holds (answer from step 1) by eight. Using the example number of gallons previously given, this equation would look as follows: 24,000 gallons ÷ 8 hours = 3,000.

## How do I choose a pool pump?

Use a standard pool gallons chart or an online pool water volume calculator to determine your pool’s size. You should then divide the total gallons your pool contains by 8 (the number of hours a pump should take to circulate the entire pool) to get the flow rate per hour you will need your pump to have.

## How many gallons of water does a pool pump need?

We have a pool that holds 15,000 gallons of water. We need to circulate 30,000 gallons of water every 24 hours – but remember, a pump has specifications of Gallons Per Minute (GPM) A 15,000-gallon pool needs about 20 GPM output if we want to run it 24 hours per day .

## How to choose the right size pool pump?

The pump must be the right size for your pool so that the filtering system operates efficiently. This guide will show you how to calculate the pool capacity, flow rate and turnover, maximum flow rate and resistance, which will give you the numbers needed to determine the proper size pump for your pool.

## Is there a maximum flow rate for a pool pump?

As our pool water makes it through the line to the pump, it is passed to another restricting element known as the pool filter. Every filter has a maximum flow rate as well, and if you go over that flow rate your water will not be filtered properly. We have included a chart so you can size your pool filter properly.

## What’s the GPH rating of a pool pump?

Since most pool pumps come with a Gallons Per Minute (GPM) rating, you now have to convert the GPH to GPM. Here’s the formula you need to do that: You’ve done the hard part, all the calculations to determine exactly what size pool pump will filter your pool’s water in a day.
