Waterway Slide Valve Piston Shaft | 500-1600

The Waterway 500-1600 Piston Shaft Assembly is designed to restore the internal function of Waterway Crystal Water and Hi-Temp slide valve systems built around the 2½ inch valve design. Produced to original Waterway engineering specifications, it refreshes the piston mechanism responsible for smooth sliding travel, tight sealing, and dependable flow direction inside the valve. The kit includes the central piston shaft along with the required O-rings, gasket materials, and sealing components needed for a complete internal rebuild. Its construction supports chemical resistance and consistent performance through repeated filtration cycles. By installing this assembly, users can revive valve function without investing in a full valve replacement, maintaining system efficiency and long-term reliability.

Additional Info

This FAQ helps online customers verify whether the Waterway 500-1600 Piston Shaft Assembly matches their slide-valve system before ordering from SOSPool.com. It also covers what to inspect when the kit arrives.

Fitment Confirmation, Valve Type & Compatibility

These answers help online shoppers make sure the assembly fits their existing equipment.

How can I confirm the 500-1600 is the right replacement?

Check your valve for Waterway Hi-Temp or Crystal Water markings and verify that it uses a 2½ inch slide-valve design. If so, this internal piston shaft assembly is typically the correct fit.

Is this kit compatible with both older and newer Waterway slide valves?

Yes. As long as the valve uses the same 2½ inch internal platform, the assembly fits across multiple production years.

Can this assembly help fix minor internal leaks?

Often yes. Replacing the worn piston and seals restores proper seating and reduces small internal bypass issues.

Seal Performance, Valve Movement & Rebuild Results

These details help online customers know what to expect once the rebuild is complete.

What improvements should I expect after installing the new shaft?

Smoother sliding action, better position alignment, and improved sealing when switching between valve settings.

Do the new seals hold up to pool and spa chemical exposure?

Yes. The materials are engineered for durability under typical filter-system chemical conditions.

Will this improve valve longevity?

Yes. Installing new internal components can extend the service life of the valve and delay full replacement.

Shipping, Delivery Inspection & Installation Prep

These answers support customers after receiving their order from SOSPool.com.

How is the piston shaft assembly packaged?

It ships with protective cushioning around the seals and shaft to prevent deformation during transit.

What should I inspect once the kit arrives?

Ensure the seals, shaft ends, and gasket edges are free of dents or compression marks from shipping.

Is the kit ready for installation?

Yes. After removing the old components and cleaning the valve chamber, the new assembly is ready to install right away.
