Product details

The Hayward Pro-Grid is a vertical grid diatomaceous earth filter, and this is the 48 sq. ft. size with a 120 GPM residential flow rate. It is built for inground pools, inground spas and pool and spa combinations, and Hayward positions the 48 sq. ft. model for both commercial work and large residential pools. The valve is not included.

How it is built

The tank is reinforced thermoplastic, chosen to hold up to hard duty and harsh conditions including in floor cleaning systems. A heavy duty tamper proof one piece flange clamp holds the top and bottom together and lets you open the filter without disturbing the piping. Inside, high impact grid elements are laid out for up flow filtration and top down backwashing, and an inlet diffuser elbow spreads unfiltered water and fresh D.E. evenly across all of the grids. Plumbing is 2" full flow throughout for less resistance.

Servicing

The tank top and bottom are self aligning, and the uniform low profile base with integral lift handles is there so the grid nest comes out in one piece rather than fighting you. A high capacity rapid release manual air relief valve bleeds trapped air with a quarter turn of the lever.

Choosing the valve

Because the valve is a separate purchase, decide on it with the filter. Hayward lists SP0740DE, the Selecta-Flo 2" SKT, and SP0710XR50, the Vari-Flo 1 1/2" NPT, as compatible, with SP0715XR50 in Vari-Flo 2" NPT and SP0410X5025 slide valve in 2" SKT as further options.

Questions and answers

What people ask about this product, answered by our pool techs.

Does this filter come with a valve?
No. The valve is sold separately. Hayward lists SP0740DE (Selecta-Flo 2" SKT) and SP0710XR50 (Vari-Flo 1 1/2" NPT) as compatible, with SP0715XR50 (Vari-Flo 2" NPT) and SP0410X5025 (Slide Valve 2" SKT) as options.
How big a pool will 48 sq ft handle?
Hayward rates this filter at a 120 GPM residential flow rate and positions the 48 sq. ft. size for both commercial and large residential pools.
Is the part number DE4820 or W3DE4820?
The product record carries both. W3DE4820 is the manufacturer part number listed for this filter and DE4820 appears in the same record, so match whichever number your paperwork or old filter shows.
How hard is it to service the grids?
The tank top and bottom self align and the one piece flange clamp opens the tank without touching the plumbing. The low profile base and integral lift handles are there to get the grid nest out in one piece.
