Pentair 520595 Union Replacement Pool Spa Sanitizer and Automation Control Systems

Before You Buy

This guide is for the Pentair union identified by the current Amazon listing as part/model 520595. The listing describes it as a Pentair union for IntelliChlor in a quantity-two presentation, so confirm your salt chlorinator documentation calls for that same union rather than another fitting.

Checklist

• Match the part number: compare 520595 to your existing union or service manual before ordering.
• Confirm quantity: the listing states "Quantity 2," so verify whether you need two replacements or only one.
• Do not assume cross-fit: unions can look similar, but different chlorinator models may use different hardware unless your manual confirms it.
