Determine how many gallons you need to pump per hour to clean all the water in your pool in eight hours. Divide the gallons of water your pool holds (answer from step 1) by eight. Using the example number of gallons previously given, this equation would look as follows: 24,000 gallons ÷ 8 hours = 3,000.

How do I calculate what size pool pump I need?

Sizing the Pump for Your Swimming Pool

  1. Circular Pools: Diameter (ft.) x Diameter (ft.) x Average Depth (ft.) x 5.9 = Total pool capacity in gallons.
  2. Oval Pools: Length (ft.) x Width (ft.) x Average Depth (ft.) x 6.7 = Total pool capacity in gallons.
  3. Rectangular Pools: Length (ft.) x Width (ft.) x Average Depth (ft.)





How do I choose the right HP for my pool pump?

To get that figure, divide the GPH by 60 to calculate how many gallons per minute (GPM) need to be pumped for full turnover. Once you have all the numbers, you can find the size of pump that will accommodate the GPM required for your pool and turn over the pool’s water in one eight-hour period.

How do you size a pump and filter for a pool?

Quote from the video:
Quote from Youtube video: We recommend over sizing the filter to be absolutely. Certain it can handle the flow coming from the pump. Most pool filters will have a tank label indicating maximum flow. So make sure your pump flow

What size pump do I need for a 15000 gallon pool?

10,000 – 15,000 gallon pools need a pool pump with flow rate between 20 and 35 GPM. Based on our flow rate per pump size(in hp) table above, a 1hp pool pump will generate this flow rate.

Can a pump be too big for a pool?





Usually, the mindset of pool owners is that a bigger pump is better. A bigger pump is not better. A pool pump can actually be too big for a pool.

Can I replace a 1hp pool pump with a 1.5 HP?

Conclusion. So to answer the question, yes, you can replace your 1hp pool pump with a 1.5hp pool pump, but only if your situation calls for it. If you’ve determined that your current pump is too small for your pool, then we’ll suggest replacing it with a larger ECO pump like the Water TechniX Pump Alpha ECO.

What is the difference between 1 HP and 1.5 HP pool pump?

As I mentioned before, the 1.5 HP PowerFlo LX has only 1 GPM more flow rate than the 1 HP PowerFlo LX so very little difference between the two pumps. However, for an 18″ filter, you don’t want to exceed more than about 35 GPM.

What size pump do I need for a 10000 gallon above ground pool?

For round above ground pools up to 24 ft. ( pools with less than 15,300 gallons) use a 1 HP pump. For round above ground pools over 24 ft. (pools with more than 15.300 gallons) use a 1.5 HP pump.

How many gallons per minute does a 1 hp pump?



The typical efficiency of most hydraulic equipment runs at about 60 percent to 75 percent. One horsepower equals 3,960 gallons/minute/feet.

How do I know what GPM my pool pump is?

As a general rule of thumb, sand filters typically fall between 19-22 Max GPM per square foot of surface area.

  1. 1.8 square feet surface area = 40 GPM.
  2. 2.3 square feet surface area = 50 GPM.
  3. 3.1 square feet surface area = 60 GPM.
  4. 4.9 square feet surface area = 100 GPM.


Is a 1.5 HP pool pump good?



A 1-horsepower pump with the same resistance will work for pools up to 26,000 gallons, while a 1.5-horsepower pump is suitable for large pools up to 30,000 gallons. A massive 2-horsepower pump can clean pools up to 46,000 gallons.

What happens if I oversize my pool pump?

A pool pump that is larger than needed has a more powerful motor and circulates water at a higher flow rate. This uses significantly more energy to pump the same amount of water and puts additional stress on your pipes and filter, meaning you’ll need to replace them sooner.

What happens if your pool pump is too small?

If a pool pump is too small for the size of the pool it is forced to work much harder to keep up, running more often and therefore decreasing the pump’s lifespan. In general, there are two different types of pumps; single speed and variable speed.

What happens if pool pump is too big for pool?

Too large of a pump can cause poor filter performance and even damage it, if the filter is not also oversized accordingly. Another possible consequence is pump cavitation in which bubbles form in the water inside the pump and then burst with great force, resulting in damage to the impeller and other internal parts.

Should you turn off pool pump while swimming?



Many of the INTEX pump/filters are NOT UL rated and you should not swim with them plugged in. They do have one or two that are UL rated and can be left on while swimming. Just about all other pool equipment brands can be used while you are in the pool when properly installed.

How many hours a day should you run a pool pump?

Is it OK to run pool pump 24 hours a day?

A Rule of Thumb



Generally running your pool pump for 12-hours a day is a good option. This is based on the assumption that your average pool pump has a turnover rate of about 8 to 12-hours. That means that the total volume of your pool water will filter through your system 2 to 3 times per 24-hour period.

Does a pool pump use a lot of electricity?



Outside of the air conditioner, the pool pump is the largest electricity consumer in the average pool-containing home. According to the study, at the national average of 11.8 cents per KWh, a pool pump alone can add as much as $300 a year to an electric bill.

Should I turn off pool pump when raining?
