How do I know what pool filter I need?

Author: Prof. Adrian Hammes  |  Last update: Friday, May 6, 2022

The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it's best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.

How do I know what size pool filter I need?

The equation used in calculating filter sizes is:
  1. Pool capacity in gallons divided by the desired turnover rate in hours.
  2. This will give you the minimum flow needed in gal/m (Gallons per minute).
  3. Divide this number by 60 to get the gal/m.
  4. Find a pump that meets the gal/m you just calculated.

How do I know which pool filter I have?

All pool filters are labeled with an information tag on their tank. This tag includes the name of the manufacturer, model name, the various sizes of the filter in that line of models. The size of your specific unit should be marked or highlighted on this tag.

How do I know what pool pump to buy?

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.

Is a bigger pool filter better?

The combination of pump and filter is called the filtration system. Filtration systems collect dust, dirt, oils, hair and other small particles to keep your pool water clear and free of debris. The larger the filter you have, the better job it will do and the less frequently you will need to clean it.

What Size Pool Filter Do I Need?

What is the easiest pool filter to maintain?

Sand filters use 20-grade silica sand capable of trapping particles as small as 20-30 microns. Maintenance: Sand filters are considered to be the easiest to maintain. Sand filters are backwashed when the pressure reads 10 psi over the normal operating level.

What size pump do I need?

A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. For example, a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond. You don't have to refer to a fountain pump size chart to figure out the best water pumps for your garden.

How do I know what size water pump I need?

Use the pump flowrate calculation: Divide the container volume by the length of time it took to fill up to get the flow rate. 5 gallons / 1 minute = 5 gallons per minute. 5 gallons /30 seconds (0.5 minutes) = 10 gallons per minute.

What is the difference between a pool pump and a pool motor?

The pump's shaft spins up to 3,450 revolutions per minute to turn the impeller to draw water from your pool and then push it through your filter and back to the pool. The motor is a cylindrical steel enclosure, usually black but sometimes gold or almond-colored, bolted to the back end of the wet end.

How can I tell what model Hayward pool filter I have?

Often these numbers appear on product labels with spaces or parentheses. Model number is found on the dataplate located on the bottom right of the electrical cover on Hayward Heat Pro units.

How do I know if I have a sand filter in my pool?

If your swimming pool begins to seem a bit cloudy or unclear, then you may have a sand filter that's running slowly. ... It can look like how it's supposed to but not be filtering debris from your pool as it should. If you're suspicious of this, the first thing you should do is test the water chemistry.

Are s1 and D filters the same?

Are these the same as type D filters? Answer: All I know is that they are exactly the same as the filters that came with our spa.

What size above ground pool filter do I need?

When choosing a pool filter for your above ground pool, a helpful tip is to choose one that is at least 1 sq. ft per 10,000 gallons pool capacity. For example: the ClearWater 16″ Sand Filter System has a 1.55″ sq. ft filtration area, making it perfect for a 15,000 gallon pool.

How do I calculate pump motor size?

Pump Hydraulic Power (ph) = (D x Q x H x9.

Pump Hydraulic Power (ph) = (1000 x 0.005 x 65 x9. 87)/1000 =3KW. Motor/ Pump Shaft Power (ps)= ph / pe = 3 / 80% = 4KW. Required Motor Size: ps / me =4 / 90% = 4.5 KW.

Can a pump be too big for a pool?

You might think bigger is better in terms of pump size, but a pump that is too big can cause serious problems. In the example above, the pool's average depth is 8 feet. Now use the formulas below to determine the volume of water in your pool.

Can I replace my 1hp 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.

Is 1 HP pool pump enough?

Pool owners often mistakenly believe if they choose a 2 HP pump over a 1 HP pump, they are getting double the performance. This is simply not true. In this scenario, you will get only about 15% more flow from the 2 HP model. But the amp draw of the larger pump will be significantly higher, raising your electric bill.

Is a sand or DE filter better?

Sand filters are least effective but also the least expensive to buy and use. Cartridge filters are more effective but are more expensive to buy and use. DE filters are the most effective but are the most expensive to buy and use.

Which pool filter is better sand or cartridge?

Cartridge filters can screen out twice as much dirt and debris as a sand filter. Its larger filtration area allows the water to progress through the cartridge removing smaller particles. Maintenance is much easier in that there is no need for a back-washing step.

Is DE filter better than cartridge?

A DE filter will work better on smaller particles while a cartridge filter will work more efficiently with larger types of debris.

Can a pool be over filtered?

No. The reason being is that there is no true “minimum flow rate” of a filter. The tank may take longer to fill up if we have a ½ HP pump on a 800 pound commercial sand tank but the filter will still scrub the water to the same standard.

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.
