How do I calculate pool pump flow rate?

Divide the total gallons of water in the pool by the turnover rate in hours. Ideal turnover rate is between six and eight hours. To run the pump less time each day, lower the turnover rate. This will give you the gallons per hour or GPH.

How do I know what size pool pump I need?





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.

What is a pool return line?

The return line is the pipe that carries water from the pool filter, back to the wall return inlets. Other plumbing lines may be connected to step jets, a pool cleaner line, or fountains and water features. Pool plumbing is done after the pool walls are erected, about halfway through the process.

What is the GPM of my pool pump?

Count the intake lines and you will see what the maximum flow into the pump will be. For each 2.0 inch intake line, the maximum flow into the pump will be 73 gallons per minute (GPM). For each 1.5 inch intake line, the maximum flow into the pump will be 42 gallons per minute (GPM).

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

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.

How many gallons per minute does a 1.5 HP pool pump?





Pool Pump Operating Costs

Pump Size GPM (varies with plumbing) Cost/Hour
1.0 HP 60 $0.06
1.5 HP 68 $0.09
2.0 HP 76 $0.12
3.0 HP 85 $0.18

Can a pump be too big for a pool?

Yes, a pump can be too big. It needs to be properly sized for the plumbing and filter.

Is a bigger pool filter better?

Maintenance. The main advantage to over-sizing a filter is the reduction of cleaning throughout the pool season. With the larger filter there is more media in which the dirt can disperse, allowing water to flow freely. The larger the cartridge, the more dirt it can trap.

Does HP matter for pool pump?

For instance, a pool with water features (deck jets, waterfall, etc) tied into the main pool pump might require a higher horsepower to provide enough flow. The same would hold true for installations with a spa or solar panels running off of the pool pump. Long runs of pipe might also require more power.

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 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.

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 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.

How much suction should a pool pump have?

Most pool filter systems should have a pressure of 50-75Kpa (kilopascal) or 10 – 25 psi.

How much HP pump do I need?

Horsepower theoretically required for pumping water equals the gallons per minute multiplied by the head in feet, and divided by 4.000 For power recommended, divide by 2000 instead of 4000.

How high can a 1/2 HP pump push water?

You can expect a 1/2 HP submersible pump to raise your water up to 10 feet out of the ground. This lift rate makes the 1/2 HP pump ideal for homes closer to sea level. 1/2 HP pumps tend to have shorter pipe lengths than their competitors, as well.

How many liters per minute does a 1.5 HP pump pumps?



7.61×60 = 456 litre per minute.
