Product details
The Zodiac R0443900 is the valve top assembly for the Jandy Pro Series 2 inch side mount multiport valve. It replaces the working top of the valve as a single unit.
Why the top and not the valve
Everything that moves in a multiport lives in the top: the rotor, its seals and the handle mechanism. The body is a plumbed casting that normally lasts as long as the filter. Replacing the top assembly restores clean separation between the ports without cutting the valve out of the pipework.
What worn internals look like
Water bleeding to waste while the valve is set to filter, a backwash that never runs strongly, or a handle that no longer locks positively into a position are all signs the top is finished. Check the size first: this is the 2 inch assembly, and the 1-1/2 inch valve takes a different part.
