How to Change a Sand Filter

Pool sand filters are extremely useful for reducing the overall amount of debris present in the water, as well as maintain the pristine, clear aspect. While there are several models of filters, as their wide range caters to several basin types, the overall procedure for replacing one is almost the same for all. What is changed, in fact, is not the filter itself, but rather the sand inside it. With time, the sand loses its roughness, thus the filtering ability diminishes. When that happens, it’s high time to replace the sand with a new one.

Replacing Period

Usually, the sand won’t deteriorate too fast, so you won’t have to change it as often as other filter types. It needs anywhere from 2 to 3 years to lose its shape, and depending on how often you use the pool, it might even last up to 5 or 6 years. A sure sign, however, that it needs to be replaced, is the murkiness of the water, its cloudy aspect, as well as the often use of the backwash setting. Another sign is indicated by the pool cleaner having increased difficulty in keeping the water clean.

A correct storage ensures a long utilization period, away from early deterioration due to sun rays.
Required Materials

Before you start working on it, you’ll need the following materials:

  • Sand extractor or a powerful shop vacuum
  • New O-rings – depending on the model of the filter, you’ll need anywhere from 1 to 3.
  • A screwdriver – preferably an automatic/electric type
  • A plug or small plastic bag and rope
  • Filter gel (optional)
Procedure

Although the procedure itself is not difficult to do, there are some steps that need to be followed:

  1. Take a look at the filter and identify how many bags you’ll need to fill it up again. The sand you’ll have to purchase is specially made for filters – so play sand shouldn’t be used. Additionally, depending on the size of the filter, you’ll need the according amount of sand packs.
  2. Use the screwdriver and remove the lid on the filter. Depending on the model this step can be engaged directly, or you’ll have to remove other elements first – like a collar, or connection hoses.
  3. Once the cap is off, remove the water present in the tank – by unscrewing the lid at the bottom – or simply use the backwash option. This will help loosen the sand for better and faster extraction.
  4. In this step you can utilize either the sand extractor or the shop vac – the result will be the same. The entire quantity of sand must be removed from the tank. Once the sand has been removed, if the size allows it, either wipe it with a large sponge, to remove the remaining dirt, or wash it with water.
  5. When the tank is clean, screw the drain plug back in – if it was priorly removed – and cover the outlet pipe. You can either use the plug – if it fits – or cover it with the plastic bag and tie the rope around it. This will prevent the new sand from entering the pipe.
  6. Once everything is set, add some water (half of the tank at least), and begin to pour the new sand inside the tank. Don’t hurry, give the sand enough time to settle properly into the water. Pour another pack until there are no more packs. If you’ve brought enough sand, the tank should be at least 75% filled. Once that’s taken care of, remove the pipe plug – or plastic bag.
  7. Replace the old O-rings with the new ones – either for the main lid, or for the connection tubes, and reassemble the unit.
  8. Once all connections are tightly fit together, use the backwash setting for about 3-4 minutes. This will remove any murky water, preventing it from going into the pool, as well as evenly distribute the sand in the tank.
  9. (Optional) If you want to assure the clarity of the water, place a filter gel capsule in the skimmer basket.
  10. Set the unit on the ‘filter’ mode and you’re good to go.

The overall procedure isn’t difficult, and it can be easily achieved even by beginners. Even more, it shouldn’t be repeated too often, so this maintenance action won’t take too much of your time.

When it comes to keeping the swimming pool water clear, free of debris and particles, while a smooth high-end circulation is assured, naturally, every pool owner wishes only for the best. And since there are more than one types of filters to choose from, the question of their proficiency arises. Although both sand and cartridge types have, basically, the same principle in mind – preserving the water’s purity – the medium through which they achieve the task is distinct.

Sand Filters

These types of filters are quite frequently employed for pool-keeping, and for a good reason too. They are quite affordable, and easy to install, whereas their maintenance is also simple and straightforward. They are suitable for surface-placed basins as well as inground types, employing a high GPM flow rate. Due to their sharp, rough, structure, the sand will hold residues as small as 20 microns, returning only clean water to the basin. Although their cleaning mechanism is hassle-free – just a backwash – its frequent utilization will perturb the chemical balance of the water.

Benefits Drawbacks
Compact and affordable Backwash will disrupt the chemical balance
Doesn’t need often cleaning Utilizes high GPM
Removes fine particles
Sand replacement is done every 5 to 8 years
Low maintenance cost

Cartridge Filters

They provide a larger residue-holding capacity, like the surface that encounters dirt is larger, and also thicker, capturing pieces as tiny as 10 microns. With a simpler maintenance process than their counterparts – a simple wash will be sufficient – the period between the cleaning cycles is shorter. More economical, they utilize low pump pressure, but in turn, they are better suited for smaller basins rather than spacious ones. Even though they imply lower costs on electricity, as they won’t overwork the pump, their upfront price is higher.

Benefits Drawbacks
Larger debris capacity High upfront price
Easier maintenance/cleaning More frequent cleaning – every year
Utilizes low GPM Better suited for smaller basins
Low impact on the chemical level
Removes extra-fine particles


All in all, it is entirely up to your preferences which type of filter better suits your pool. If you don’t want to be bothered with frequent maintenance work and change the medium only once in a while, the sand filter is perfect. However, if you’d rather engage frequently in maintaining your pool sparkly-clean, a cartridge filter will do the trick. In the end, regardless of your choices, you’ll have clean, impurity-free water for swimming.


Final Thoughts

Keeping the water from your pool free from debris and harmful particle is highly important. A sand filter is not only cost-efficient, but it can also deal with tiny, microscopic particles, leaving the water clean and clear.
