How To Summate Pool Pump Run Time

If you have a pool, then you most assuredly have a pool filter pump. Only how long should you run the filter pump? Knowing that a pool pump filter system is the second highest energy consumer during the summer, (subsequently Air-conditioning units), we desire you to go the nigh bang for your buck.

Allow's walk through a few common questions and then breakdown the calculation behind finding the ideal pool filter pump run fourth dimension for your swimming pool. We will show yous the standard calculation and a simple adding.

What does the pool filter pump do?

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

How many gallons of water are in my pool?

Earlier we starting time, allow's empathize how many gallons of h2o are in your pool. To find your puddle'southward volume, use one of these like shooting fish in a barrel calculations. If you don't desire to summate the pool volume, have a quick look at the table on this helpful article: Calculating Puddle Volume.

Square and Rectangle Pools with Single Depth:

Length x Width x Depth ten vii.v = Approximate Book (Gallons)

Square and Rectangle Pools with Variable Depths:

Length 10 Width x Boilerplate Depth 10 7.5 = Guess Volume (Gallons)

Average Depth: If the pool has a shallow end and a deep cease, add the two depths together and split by two. (Case: The shallow finish is three' deep and the deep finish is 8'. Using the Average Depth formula: (three+viii)÷2=five.5' Average Depth.)

Round Pools:

3.14 x Radius x Radius x Boilerplate Depth ten 7.5 = Volume (Gallons)

The Radius equals the diameter divided by 2. (Instance: A sixteen' diameter divided by 2 = 8' radius.)

Note: Most round pools have a single depth.

Oval Pools:

three.14 x Length x Width x .25 x Average Depth 10 7.5 = Guess Volume (Gallons)

Kidney-Shaped Puddle:

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

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

Irregular Shaped or Costless-Class Pools:

Longest Length x Widest Width x Average Depth x 5.nine = Judge Volume (Gallons)

What is the Turnover Rate?

Now that we have the puddle volume in gallons, nosotros can calculate the Turnover Charge per unit. The water period of Flow Rate for all pool filter pumps is measured in gallons per infinitesimal (GPM), versus gallons per hour (GPH). Here is how to become that number:

Total Pool Book ÷ 8 = GPH

GPH ÷ 60 = GPM

Let'southward do some math!

At present that we have gallons per minute (GPM) and pool volume, we tin can summate the run time. The math is simple. For this example, let's say you take a 20,000 gallon pool and the pool pump has a GPM rating of xl. Catch that figurer and just "sub-in" your measurements for these:

xl (GPM) 10 60 (minutes per 60 minutes) = 2400 gallons per hour

20,000 (gallons) / 2400 (gallons per hour) = eight.iii hours

In this case, the ideal pool filter pump run time is eight.iii hours per day for one apportionment or "turnover" of water.

A simpler adding

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 high:

Run the apportionment system 1 (1) hour for every 10°F of air temperature if a single-speed filter pump is installed.

Example: If information technology is 100°F, the pump should run 10 hours a day minimum. Of class, if the pool is full of algae or a major atmospheric condition issue has occurred, the pump may need to run 24-hours a twenty-four hour period.

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 twenty-four hour period (3-4 hours on loftier speed for the pool cleaning system and 8-9 hours on low speed for filtration). Keep in mind that sure water features — Common salt Water Chlorine Generators and heaters — may not operate properly or even plough on if the filter pump is running on low speed.
