Hayward Slide Valve Assembly for Pro-Grid D.E. Filters — 2" Pipe, Preassembled Full-Flow

The Hayward SP0410X502S Micro-Clear Slide Valve Assembly is a factory-ready 2" push/pull backwash valve with integrated 2-inch pipe for Hayward Pro-Grid vertical D.E. pool filters.

This slide valve assembly is designed as a direct replacement or upgrade for Hayward D.E. (diatomaceous earth) pool filters that use the Pro-Grid vertical grid system. It combines a push/pull backwash mechanism with full-bore 2-inch internal plumbing to minimize flow resistance during normal filtration and backwash cycles. The assembly ships preassembled so you can install it quickly without additional parts or time-consuming assembly steps.

How does this slide valve improve flow and backwash efficiency?

The SP0410X502S uses a 2-inch full-flow internal pipe that reduces constrictions in the plumbing, helping maintain higher water throughput during filtration and backwash. Its push/pull design offers a simple, reliable control method that requires minimal effort to change filter modes.

• 2" internal piping for reduced hydraulic resistance
• Push/pull operation for quick mode changes
• Engineered to match Pro-Grid vertical D.E. filter geometry
• Preassembled unit eliminates leak-prone field joins

What are the installation and compatibility details I should know?

The valve is supplied specifically for Hayward Pro-Grid vertical D.E. filters and fits systems using the corresponding slide-valve interface and 2-inch plumbing. No assembly is required, but confirm your filter model and plumbing size before ordering to ensure a correct fit.

• Intended for Pro-Grid vertical D.E. filter models
• 2" pipe connection—verify your system plumbing matches
• Preassembled for straightforward replacement installs
• Standard push/pull handle for manual operation

How does the SP0410X502S hold up to routine pool maintenance?

Designed for residential and light commercial pools that use D.E. filtration, the slide valve handles repeated backwash cycles and normal seasonal use. The robust internal piping and factory assembly reduce wear points and potential leaks that can occur with aftermarket plumbing modifications.

• Durable 2" internal plumbing for repeated cycles
• Factory-assembled to minimize installation errors
• Simplified push/pull action reduces operator error
• Suitable for regular maintenance and seasonal servicing

What should I expect in terms of physical features and care?

The assembly arrives ready to install and includes the slide valve body and 2-inch coupling. Basic care includes periodic inspection of seals and the handle mechanism, and winterization or draining according to your local pool maintenance practices.

• Ships fully assembled—no on-site coupling required
• Check seals and O-rings periodically for wear
• Follow standard pool winterization to prevent freeze damage
• Replace if visibly cracked or leaking under pressure

Who is this for: Pool owners, service professionals, and maintenance crews who operate Hayward Pro-Grid vertical D.E. filters and want a reliable, factory-assembled push/pull backwash valve with full 2-inch flow capacity. If you need a straightforward replacement that reduces plumbing resistance and simplifies backwash operation without extra assembly, the Hayward SP0410X502S is built for that purpose.
