Details
The INTELLICHLOR REPLACEMENT UNIONS - SALT are critical components that create a watertight seal between your Pentair IntelliChlor salt chlorine generator and your pool's piping. They are designed to be tightened and loosened for maintenance or removal of the IntelliChlor unit. However, the rubber seals inside these unions are subject to wear and tear from continuous contact with water, chlorine, and other pool chemicals. This constant exposure can cause the seals to become brittle, cracked, or compressed over time, compromising their ability to hold a seal.
When these unions begin to fail, you'll typically observe leaks around the connection points. If left unaddressed, these leaks can worsen, potentially leading to significant water loss, damage to surrounding equipment from prolonged moisture exposure, or even a complete loss of connection for the IntelliChlor unit. This would prevent the generator from functioning, meaning your pool water would no longer be sanitized by the salt chlorine system, leading to cloudy or unsafe water conditions.

Always ensure the union threads are clean and lubricated with a silicone-based lubricant before reassembly to ensure a good seal and ease of future removal. Hand-tighten firmly, then give it about a quarter turn with a wrench for a secure fit.
