This pool has an in-ground cleaning system with floor heads. I replaced a 48 square foot DE filter, because the tank cracked and it was leaking water under pressure. I believe this happened because the filter was undersized. A pool with a suction side cleaner runs a lower pressure, about 10-13 pounds usually. A pool with an in-ground cleaning system will run between 20-25 pounds of pressure. Its important to match the pool equipment to the system, not based on price. Depending on the size of the pool, the distance the equipment is away from the pool, whether it has a spa, a heater, the type of cleaning system it has, the diameter of the pipe, if there are water features etc, all determine what size pump is used, how much water the pump is supposed to move and what size filter is required to handle the flow rate.
This 60 square foot filter was installed to lower the pressure at the filter. The old, 48 square foot DE filter was running a high pressure, 30-35 pounds per square inch. The 60 square foot DE filter is running at 20-25 pounds per square inch. 10 pounds per square inch is a lot. This filter will last longer with proper maintenance than the last, because the lower pressure puts less stress on the collection manifold and grids...not to mention the tank.
