HOW LONG DOES SAND LAST IN MY SAND FILTER?
Most sand will last between 4-5 years but this is dependant on how well the pool water quality has been maintained. For example if the pool water chemistry has not been kept in balance, this may have caused calcium to build up in the system, turning the sand into a solid lump.
When the sand is coming to the end of its effective life the following points may be noticed:
The normal (clean) running pressure may have increased by 10% or more.
The frequency of backwashing may need to be stepped up. Water flow when backwashing appears less vigorous than when the sand was new.
The pool water condition may be difficult to maintain, causing water clarity problems.
Please note that it is advisable at least once a year for the sand to be cleaned with a de-greaser and a de-scaler.
You may find it difficult to maintain a level of chlorine in your pool water.
