How often do you have to change or clean the sand in a sand filter?
Ans: I’ve been in the trade for 30+ years and have never heard that 20 to 25 year time frame for changing the sand in a sand filter. For one, the filter alone will realistically only last 10 to 12 years – sometimes longer. Rule of thumb is to change out the sand about 5 to 6 yrs. At that 5 yr. time frame the sand looses it’s ability to hold the contaminents. The shear motion of the water will,in time, round out the sand particle – thus removing the sharp edges that sand naturally has.
