The Hayward S310T2 Pro-Series is a 30-inch top-mount sand filter designed for in-ground pools. Its size and design make it suitable for medium to large residential pools, offering a good balance between filtering capacity and space requirements. The 2-inch Vari-Flo valve is a standout feature, providing six positions that help optimize water flow while keeping pressure low, which can improve energy efficiency and filter performance.

Maintenance is simplified thanks to the system’s design for quick assembly and precise alignment, making it easier to clean and service compared to some other models. The product is engineered to match performance and energy efficiency well, which should satisfy most pool owners’ needs.

One downside to consider is the weight (83 pounds) and size, which might require some effort during installation. This model is not discontinued and enjoys strong positive reviews (4.5 out of 5 stars from over 1,800 users), although it is not at the very top of best sellers, indicating there are other options available that might have additional features or different valve types. This Hayward filter is a reliable choice for pool owners seeking a durable, energy-efficient sand filter that’s relatively easy to maintain and offers versatile flow control.

One of the key strengths is the multilateral underdrain assembly which promotes balanced flow and thorough backwashing, enhancing the filter’s efficiency.
