what to do when your pool pump does not circulate water properly

How To Summate Puddle Pump Run Time

If you have a puddle, and so you almost convincingly accept a puddle filter pump. But how long should you run the filter pump? Knowing that a puddle pump filter arrangement is the 2nd highest free energy consumer during the summer, (subsequently Ac units), we desire you to get the nigh blindside for your cadet.

Let'south walk through a few common questions and so breakdown the calculation behind finding the ideal puddle filter pump run time for your swimming pool. We volition show you the standard calculation and a simple calculation.

What does the pool filter pump practise?

To understand how much run time you need, it'due south important to know exactly what your filter pump does for your pool. The pool filter pump is the heart of your pool filtration system. It circulates h2o from the pool and returns information technology dorsum, distributing pool chemicals and filtering your water. It is recommended that y'all "turnover" or circulate all of your pool water through the pool filter at to the lowest degree in one case throughout the twenty-four hour period. This volition ensure that the chemicals are evenly distributed and your h2o stays clean and clear. If you don't circulate the water, you run the risk of algae growth and h2o balance or clarity problems. This may lead to h2o that is unsafe for swimmers.

How many gallons of water are in my pool?

Before nosotros start, let's understand how many gallons of water are in your puddle. To find your pool's volume, use one of these like shooting fish in a barrel calculations. If you don't want to calculate the puddle volume, take a quick look at the table on this helpful article: Calculating Pool Book.

Square and Rectangle Pools with Single Depth:

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

Foursquare and Rectangle Pools with Variable Depths:

Length 10 Width x Average Depth x 7.v = Approximate Volume (Gallons)

Boilerplate Depth: If the pool has a shallow end and a deep stop, add the ii depths together and carve up by 2. (Example: The shallow end is 3' deep and the deep end is eight'. Using the Average Depth formula: (iii+8)÷2=5.5' Average Depth.)

Circular Pools:

three.xiv ten Radius x Radius x Average Depth x 7.5 = Volume (Gallons)

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

Notation: Most circular pools have a single depth.

Oval Pools:

three.14 x Length ten Width x .25 x Boilerplate Depth 10 7.5 =  Judge Book (Gallons)

Kidney-Shaped Pool:

(A + B) ten Length 10 0.45 x Average Depth x vii.v = Approximate Volume (Gallons)

("A" and
"B" = Width at 2 widest points)

Irregular Shaped or Free-Course Pools:

Longest Length ten Widest Width x Average Depth x 5.9 = Approximate Volume (Gallons)

What is the Turnover Rate?

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

Total Pool Volume ÷ 8 = GPH

GPH ÷ 60 = GPM

Allow'due south do some math!

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

forty (GPM) X 60 (minutes per hour) = 2400 gallons per hr

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

In this example, the ideal pool filter pump run time is 8.3 hours per mean solar day for one circulation or "turnover" of water.

A simpler adding

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

Run the circulation organisation i (one) hour for every 10°F of air temperature if a unmarried-speed filter pump is installed.

Case: If it is 100°F, the pump should run ten hours a day minimum. Of grade, if the pool is total of algae or a major weather consequence has occurred, the pump may need to run 24-hours a twenty-four hours.

Variable-Speed Pumps:

Variable-speed filter pumps should run longer, based upon the operating speed. About pool owners run their variable-speed pump 12 hours per twenty-four hours (3-four hours on loftier speed for the puddle cleaning system and 8-9 hours on low speed for filtration). Keep in heed that  certain water features — Salt Water Chlorine Generators and heaters — may not operate properly or fifty-fifty plow on if the filter pump is running on low speed.
