Swimming pool sand filter: advantages, disadvantages

The sand filter is a natural device that allows you to enjoy clean and clear bathing water. Its operation is simple and practical and this type of product has the advantage of being economical to purchase and use. It, therefore, offers excellent value for money. If the sand filter has many advantages, it is not without constraints. Let’s take a look at how it works and its features.

How does the pool sand filter work?

In the swimming pool, the water circulates thanks to the action of the pump. It is filtered thanks to the filtration system which eliminates residues and impurities and thus offers you a cleaner swim in healthier water. It is a reliable and natural device which must however be properly maintained to function properly.

The sand filter is made up of several elements which make it possible to filter, sieve, and purify the water:

  • The tank: made of polyethylene or polyester and fiberglass, the tank contains sand which serves as a filtering mass and which retains the impurities of the water before it returns to the pool.
  • The multi-way valve: it triggers the filtration process by allowing the circulation of water and it also eliminates the impurities contained in the filter by a system of backwashing and rinsing. This valve contains 6 to 7 ways for inground pools and 4 ways for above-ground models.
  • The pressure gauge: this indicating device controls the pressure of the filter and indicates when backwashing must be carried out.

For proper use we recommend Poolking sand filter, choose a model that corresponds well to the volume of your pool. However, pools that get dirty quickly require the addition of a flocculant to facilitate its filtering action (15 to 20 microns on average). The effect is immediate, but it is a chemical product, which can be a negative point.

How to properly maintain your sand filter?

Maintenance of the sand filter is quick and relatively simple. Good news, because it needs to be done regularly to avoid premature clogging and wear. The more the water is polluted by its environment (residue, plant debris, insects, pollution, etc.), the more frequent the maintenance will obviously be.

You should rely on the indications of the pressure gauge to know when the filter needs to be cleaned. On average, this type of filter should be cleaned two to four times a year and replaced every five years.The large models equipped with 6 or 7 ways are easy to clean, since it is enough to engage the cleaning position which works by a system of backwashing.

What are the benefits of a sand filter?

The sand filter is a device that has significant advantages:

  •         Its use is simple, fast and practical.
  •         It is easy to install and clean, which is all the more appreciable, since the latter is frequent.
  •         Its price is low compared to other types of filters on the market. It is a product with excellent value for money.
  •         It has the advantage of also being economical to use.
  •         The pool sand filter tolerates all types of water (fresh, salt, hard, etc.) and all treatments (bromine, chlorine, etc.).
  •         Its maintenance and operation do not require the services of a professional, which is also a way to save money.
  •         Its processing speed is fast and it is effective in filtering bathing water.

What are the disadvantages of a sand filter?

If it is advantageous, the sand filter is not exempt from certain disadvantages:

  • Its cleaning is simple and easy to carry out, but it works by a system of backwashing, which involves a great consumption of water.
  • The quality of filtration is certain, but it is limited. It filters large residues perfectly well, but the smallest escapes it most often. However, with the use of a flocculant, this problem is easily resolved.
  • It is a bulky and ungraceful device, which can be cumbersome in the pool.
