The US swimming market reached $1.56 billion in 2019 but saw a reduction of 35.3% in 2020. Nonetheless, the demand for a private pool climbed back to the top. 

Among the many essential parts is the pool pump. It ensures you have enough water, and it stays chlorinated and healthy. So, choosing the correct pump size is vital. 

A bigger pump than needed will spend more energy, while a smaller one may cause dead spots in the pool – a breeding ground for moss or bacteria.

So, before going to a pool pump repair Las Vegas, read this article to learn how to pick a pump size.


Steps to Calculate the Right Pool Pump Size

Below we break down how to measure your pool pump size in several steps.


Step 1: Measure Water Volume

To calculate the water volume, you need to consider the dimensions of your pool. This depends on the shape, length, width, depth, and other similar features. You can use this calculation to find the volume:

Length x Width x Average Depth x 7.5 = Volume (in gallons)


Step 2: Measure Minimum Water Flow

Once you have the water volume, the next step is measuring the water flow of your pool. To do this, you need the average daily number of turnovers, which for most pools is 2. The formula for this calculation would be:

Pool Volume x Average Daily Turnover = Flow Rate

Note here that there are several options based on how long your pump would be running. The commons cycles are 6-hour, 8-hour, or 10-hour.


Step 3: Measure Maximum Water Flow

The good news is that you don’t need any calculations when measuring the maximum flow rate. This depends on the pool equipment, which usually states the maximum flow rate, saving you a lot of time.


Step 4: Choose the Range of Water Flow

Once you have the minimum and maximum flow rates, the rest of the journey for finding the right pool pump size goes smoother. Here is the formula you can use for this step:

(Minimum Water Flow + Maximum Water Flow) / 2 = Flow Rage for Your Pump


Step 5: Check the TDH

TDH or Total Dynamic Head is actually the plumbing resistance. This part tells you the hydraulic system’s resistance. In most cases, the TDH is calculated only when the pool equipment is further from the pool. 

Usually, for above-the-ground pools, the TDH is 30, while for in-ground pools, it goes around 50 TDH. 

Nonetheless, if you require to calculate the precise number, it’s always advised to consult with a professional.
