How To Summate Pool Pump Run Time

If you have a pool, and so you almost convincingly have a pool filter pump. But how long should you run the filter pump? Knowing that a pool pump filter organisation is the 2nd highest energy consumer during the summertime, (after Air-conditioning units), we want you to become the near bang for your cadet.

Let'due south walk through a few mutual questions and then breakdown the adding behind finding the platonic pool filter pump run time for your swimming pool. We will testify you lot the standard calculation and a simple adding.

What does the pool filter pump do?

To understand how much run time you need, it'due south of import to know exactly what your filter pump does for your pool. The pool filter pump is the heart of your puddle filtration arrangement. It circulates water from the pool and returns it back, distributing pool chemicals and filtering your h2o. It is recommended that you "turnover" or broadcast all of your puddle water through the puddle filter at least one time throughout the day. This will ensure that the chemicals are evenly distributed and your water stays make clean and clear. If you don't circulate the water, yous run the gamble of algae growth and water balance or clarity issues. This may atomic number 82 to h2o that is unsafe for swimmers.

How many gallons of water are in my pool?

Before we start, let's sympathize how many gallons of h2o are in your pool. To find your pool's volume, utilise one of these piece of cake calculations. If yous don't want to summate the pool book, take a quick look at the tabular array on this helpful article: Calculating Pool Volume.

Square and Rectangle Pools with Single Depth:

Length x Width 10 Depth x seven.5 = Estimate Volume (Gallons)

Foursquare and Rectangle Pools with Variable Depths:

Length 10 Width 10 Average Depth x vii.5 = Approximate Volume (Gallons)

Average Depth: If the puddle has a shallow terminate and a deep end, add together the two depths together and divide past 2. (Example: The shallow stop is 3' deep and the deep finish is 8'. Using the Boilerplate Depth formula: (three+8)÷2=5.v' Boilerplate Depth.)

Round Pools:

iii.14 x Radius x Radius ten Average Depth x 7.v = Volume (Gallons)

The Radius equals the diameter divided past 2. (Case: A 16' bore divided by two = 8' radius.)

Note: Nigh round pools take a unmarried depth.

Oval Pools:

3.14 x Length x Width x .25 10 Average Depth ten 7.5 = Guess Book (Gallons)

Kidney-Shaped Pool:

(A + B) x Length x 0.45 x Average Depth x 7.5 = Approximate Volume (Gallons)

("A" and
"B" = Width at two widest points)

Irregular Shaped or Free-Form Pools:

Longest Length ten Widest Width ten Boilerplate Depth 10 5.9 = Estimate Volume (Gallons)

What is the Turnover Charge per unit?

Now that we have the pool volume in gallons, we can calculate the Turnover Rate. The water menstruation of Flow Charge per unit for all pool filter pumps is measured in gallons per minute (GPM), versus gallons per hr (GPH). Hither is how to get that number:

Full Pool Volume ÷ 8 = GPH

GPH ÷ threescore = GPM

Let's exercise some math!

Now that nosotros accept gallons per minute (GPM) and pool book, we can calculate the run time. The math is simple. For this example, let'due south say you have a 20,000 gallon pool and the pool pump has a GPM rating of 40. Grab that calculator and just "sub-in" your measurements for these:

40 (GPM) X sixty (minutes per hour) = 2400 gallons per hr

20,000 (gallons) / 2400 (gallons per 60 minutes) = 8.3 hours

In this case, the ideal puddle filter pump run fourth dimension is eight.3 hours per day for one circulation or "turnover" of water.

A simpler calculation

Here is a simple rule of thumb for operating your single-speed filter pump during the swim season when the temperatures and bather loads are loftier:

Run the apportionment organization ane (i) hour for every 10°F of air temperature if a single-speed filter pump is installed.

Instance: If it is 100°F, the pump should run 10 hours a day minimum. Of class, if the pool is total of algae or a major conditions event has occurred, the pump may need to run 24-hours a day.

Variable-Speed Pumps:

Variable-speed filter pumps should run longer, based upon the operating speed. Nearly pool owners run their variable-speed pump 12 hours per day (iii-4 hours on high speed for the pool cleaning organisation and viii-9 hours on depression speed for filtration). Keep in mind that certain water features — Salt Water Chlorine Generators and heaters — may not operate properly or even turn on if the filter pump is running on depression speed.
