When choosing a pump to pair with a filter, the pump's GPM rating should never exceed the filter's maximum flow rate. This one is especially important, because a pump that's too powerful for the filter won't allow it to work efficiently, and can even cause the motor to overheat or the filter to become damaged. The next step is to find the flow rate of your current pool filter (or new filter, if you're upgrading all your equipment at the same time). We'll talk about this a little more in Step 4 when we talk about pump head. Keep in mind that the GPM rate for the pump will go down the farther the pump is from the pool. GPH Turnover Rate ÷ 60 = Gallons per Minute (GPM)įor example, if we have a 15,000-gallon pool, and we're wanting a pump that can provide an 8-10 hour turnover, we would need something rated for a minimum of 1,500-1,875 GPH or 25-31 GPM. Or, if you need to know the Gallons per Minute (GPM) rating, divide the GPH rate by 60: Pool Volume ÷ Hours = Gallons per Hour (GPH) Turnover Rate To find your pool's required turnover rate, use the following equation: The ideal turnover rate for most pools is around 8-10 hours. What is the turnover rate, and how does it relate to your new pool pump? In short, turnover rate is the amount of time it takes the pump to circulate the pool's entire volume of water one time. Step 2: Determine the Minimum Turnover Rate

Head over to our blog post, How To Calculate Pool Volume.

Length x Width x Depth x 5.9 = Pool Volume (Gallons)īONUS TIP: Not a fan of math? No worries! Leslie's has a few quick reference charts to help you easily estimate the number of gallons in your pool. If your pool doesn't fit the mold of any of the above shapes, you can at least get an approximate estimate with the following formula: (Width A + Width B) x Length x 0.45 x Depth x 7.5 = Pool Volume (Gallons) Then plug those measurements into the equation below: With a kidney-shaped pool, measure the widest point in both portions of the kidney shape to get your A and B width measurements. Length x Width x Depth x 7.5 = Pool Volume (Gallons)ģ.14 × Radius 2 × Depth x 7.5 = Pool Volume (Gallons)ģ.14 x Length x Width x 0.25 x Depth x 7.5 = Pool Volume (Gallons) (Deep End + Shallow End) ÷ 2 = Average Depth If you have a sloped inground pool with a shallow end and a deep end, measure the depth of both ends to find the average:

If you have a pool with a flat, level floor, your average depth is the same throughout the pool. First things first how many gallons of water are in your pool? If you don't know off the top of your head, here are a few quick and easy calculations that will give you a close estimate.įor all these equations, your depth measurement is the average depth of the pool.
