When should I change the sand in my filter?
Reply
You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.

How often do I have to replace the sand in my filter? What is normal operating pressure?
Reply
On a "fresh start-up" a filter would operate anywhere between 10-20 psi. As a general rule of thumb you only want to backwash when the pressure increases 8-10 psi. You want to make certain that the pump is being turned off whenever you move the handle on the valve. Once backwashing is complete (3-5 minutes), you can switch to the rinse option to re-settle the sand bed. Sand will typically last 5-7 years. Premature backwashing will wear down the size of the sand which will cause difficulties such as cloudy water and higher operating pressures.

Does the filter come with sand? Should I buy regular sand?

The filter does not come with sand. You can use a synthetic sand or a No. 20 silica sand.

How do I determine what size sand filter I need for my 24,000 gal inground pool?

The pool filter has to be compatible with the size of your motor. If it is too small, the pump will try to push more water through the filter than it can handle. We also recommend buying a filter one size larger than required for a buffer. Also the larger filter will last longer and require less backwashing. If you have a 1.5 HP pump we would recommend a S310T filter. If 2.0 HP, a S360T.
