It is a porous material that erodes over time, which is why it is important to be replaced periodically. How long does it last? Depending on the pool, chemical water treatment, filtration speed, etc. There are many factors that influence the durability of flint, but it is recommended to change it every 4 or 5 years. Why should it be changed? It is a porous material, in addition to easily saturable with other pool products, it erodes and loses effectiveness. All this causes loss of quality of transparency in the water, increases the expenditure of chemical products, and also takes longer to finish filtering tasks. In addition, the replacement of flint always represents a saving. How do we know that flint needs to be changed?
