## What size pump do I need for my pool?

Measure the length (ft), the width (ft) and the average depth. The average depth is determined by adding the depth at the shallow end to the depth at the deep end and dividing by two. The formula for calculating the total gallons in a rectangular pool is: Gallons = Length x Width x Average Depth x 7.5.

## What size pool pump do I need for a 25000 gallon pool?

Flow rate is the number of gallons the pump moves per minute, and turnover is the minimum about of time to circulate all water through the filter. Your 25,000-gallon pool needs an output of 52 gallons per minute to circulate the water once every eight hours.

## Can a pool pump be too big?

Too large of a pump can cause poor filter performance and even damage it, if the filter is not also oversized accordingly. Another possible consequence is pump cavitation in which bubbles form in the water inside the pump and then burst with great force, resulting in damage to the impeller and other internal parts.

## How do you size a swimming pool pump and filter?

DETERMINE GPM REQUIRED – After you have the number of gallons in your pool (20,000 gallons for this example), you will have to calculate the Gallons Per Minute (GPM) required to filter 20,000 gallons in 8 hours. To come up with this flow rate first divide your calculated gallons by 8 for Gallons Per Hour (GPH).

## What size pool pump do I need for a 40000 gallon pool?

## Can I replace a 1hp pool pump with a 1.5 HP?

However, you can replace your 1.0 Full rated motor with a 1.5 HP uprated motor. This is because they both will have the same total horsepower. Don’t fret if your motor is not labeled uprated or full rated. In many cases, it may not be labeled at all.

## How many GPH is a 1.5 HP pump?

6,950 GPH

## How long does a pool pump last?

## What size pump do I need?

A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. So a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond. To determine the size pump you’ll need, make a few measurements and calculations. Light flow = 50 gph x waterfall width (in.)

## Do you run pool pump while swimming?

Although it’s generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time. … If your pool is in constant use, you may need to run the pump for up to eight hours per day, frequently checking the water clarity and chemical balance.

## What size filter do I need for a 15000 gallon pool?

So, let’s say you have a 15,000 gallon inground pool. With two turnovers per day, your minimum flow rate comes to 20.8 GPM. Let’s also say that you have a 2.3 square foot sand filter (50 GPM max) and 1.5″ plumbing (43 GPM).

## How do I calculate my pool turnover?

Formula for Turnover Rate:

- Divide the pool shape into areas of constant depth, or constant slopes.
- Turnover Rate(TR) = Gallons divided by Flow Rate (FR) divided by 60. Flow Rate (FR) is measured by a flow meter.
