What size filter do I need for my pool?
Selecting the right size filter for the pool is not an entirely easy task, yet you need to make sure that your pool is clean, open and safe. So at first step of choosing the right size filter of the pool is to find the right size of the pool pump.
Most of the people end up with purchasing a pool pump which is bigger than the one they want. Most of the time this can be an expensive mistake. The more significant pool pumps are costly and might increase the energy consumption rather than a usual pump. The worse part of this is that a too large pump can even overpower the filter system. On the other hand, a pump which is very small might lack power which it wants to pump efficiently and to filter the swimming pool. Eventually, it might lead to the growth of algae or bacteria.
Select the right size of pool filter
Even though you have found the correct size of the pump, in case if you select a pool filter which is small, that would create too much pressure while making the material of the filter to break down and provide the filter ineffective. In some cases, the pressure that is produced by the tiny filters may cause pressure to build within the pump. As a result, it may cause explosions or damage seriously to the pool pump. So let’s go through the below guidelines to know how to find out the perfect size pool filter.
The amount of water your pool holds
Before you choose a pool filter, you need to find out how much of water your pool can contain. It is quite simple if you got a nice rectangular shape pool, but it would be difficult when your layout of the pool is complex. There are four types of designs as rectangular, oval, round and kidney.
Pool depth- no matter what is the shape of your swimming pool, you want to calculate the average depth of your pool. If you’re going to do it, you need to find the most in-depth section of your pool and the shallowest section to identify the average among them.
Gallons per minute
You need to calculate your pool volume in gallons. Once you do it, you need to figure the number of gallons per minute that you may need the pump to handle. Most of the owners of the pools want to run their pool pump for less than eight hours. In such cases, you need to figure out how many gallons you need within a minute. But for larger pools or commercial pools you preferably need to be able to run the swimming pool four times within the day, which means you need to pump it less than six hours.
Feet of the head
You will have to consider the piping between the pump and the pool which is known as the feet of head. When you have the head more, the GPM will reduce more. Moreover, you need to consider any valves and fixtures in the piping. At least you need to have an estimate about how many feet of piping is there among the pump and pool.
Select the pool pump
When you find out your feet of the head, and the GPM all you need to do is to find the right pool pump. Almost all the retailers or manufactures of pumps would offer you a chart which indicates the GPM capacity of the pump according to many feet of head lengths. So it would be better if you know the capacity of the pool and the requirements of the pump to purchase a somewhat large pump.
