Ball valve usage varies from unit to unit. To confirm the correct part number for your system, refer to the diagram for your unit in the “Requirements and Technical Details” on product detail pages.
Please contact us if your system is built differently than the online parts diagram. Our product designs evolve over time and we are happy to help restore and/or update older systems.
