Things to Remember When Buying a Pump and a Filter for Your Pool

Posted on Saturday, 18 January 2014 01:24PM by Artful Lodger

Selecting the right size pump and filter for your pool is one of the most things to remember when making a purchase. It is important to use the right size for the pool that you have. The reason that this is important is that filtering a specific amount of water per hour is what keeps algae from growing and maintains a proper pH level. During the pool installation process, adding the pump and filter are generally the last thing before filling the pool with water and calibrating the pH levels.

Pump Type

There are a few types of pumps to consider. One that is gaining popularity is a salt sanitization system. This is a chemical free type of pool pump that requires only a small amount of salt per gallon of water in lieu of chemicals. Salt sanitization systems are ideal for homes with young children or for those with sensitive skin.

Traditional pumps require the use of chemicals and a bit more maintenance. It is ideal to perform a maintenance cleaning on traditional pumps at least once monthly. This prevents clogged passages that can reduce pressure and suction. It also helps to keep the filters cleaner and properly contain debris from recirculating back into the water.

Required Maintenance

Consider the amount of maintenance that a pool pump system will require prior to making a purchase. Some require minimal maintenance other than a filter cleaning/changing and a quick flushing of the system. Others require that parts are removed and cleaned individually on a monthly basis. If a salt sanitization system is the pump type chosen, minimal maintenance is required. Most also come with a reusable bag filter that simply needs to be emptied and rinsed out.


Pump Size

It is ideal to know how many gallons of water your pool holds when purchasing a pump. An example of an appropriate size would be a 15,000 gallon pool requiring a minimum 20GPM pump. The gallons per minute, or GPM, to sufficiently filter all of the water in the pool should be 1.5 times the volume of water in the pool. This also helps to prevent debris buildup, algae formation and spikes in pH levels. Debris can clog the return suction that is known for throwing off pH levels and allowing algae to begin to form.

Enclosed or Non-Enclosed Pump Area

The type of pump that you purchase should weigh some on whether you have an enclosed pump room or if the pump is out in the open. Pumps that are enclosed in a small room are more likely to remain in working condition without incident. Those that are out in the open, close to the pool, are susceptible to the elements and storms. It makes them vulnerable to debris.

For safety reasons, consider purchasing a pump and filter setup that does not contain copper. Unless the pool area is completely enclosed with a fence, copper is an item that is often stolen by those that are having financial difficulty. Some homeowners may want to consider a locked enclosure box to prevent copper theft.


Filter Type

Consider the options in filter type when purchasing a filter to work in your new pool pump. There are options that are disposable to use after only one cycle. A cycle is generally 30 days. Other filter types are reusable and can be cleaned for reuse for up to 12 cycles. Reusable filters simply need to be removed on a weekly basis and emptied. Once this is done, rinsing them out and placing them back in the pump is all that is needed. Filters do all have to be replaced at some point.


It is very important to use the right size pump along with the recommended chemicals for that pump. Pumps that have piping that is made of metal will benefit better from non-corrosive chemicals. Pumps that have piping made from PVC or other materials of the type can use any type of chemical. Take the time to consider salt sanitization systems as they are less costly to maintain and are an all natural way to keep pool water clean and prevent algae from growing.
