Pentair 520588 Pass-Through Dummy Bypass Cell
The Pentair 520588 is a maintenance kit designed for salt-chlorination systems that allows uninterrupted water flow while bypassing the salt cell during winter shutdown or chemical treatment cycles.
Key Features
- Installs in place of the salt-cell so the plumbing remains open and water can still flow.
- Protects the salt-cell from damage during off-season periods, harsh chemicals or peak load situations.
- Compact footprint — typically fits into the existing union or cell fitting with minimal change-out.
- Time-saving service part for technicians: reduces need to remove plumbing or install temporary tubing when bypassing the salt-cell.
Technical Specifications
- Part Number: 520588
- Application: Salt-chlorinator systems — bypass dummy cell for winterization or startup.
- Use Case: In-line installation when salt-cell removed or taken out of service.
- Material & Construction: High-quality molded body engineered for pool system duty.
Installation & Compatibility Notes
Shut off system power and relieve pressure before installation. Remove the existing salt-cell from system plumbing, then install the dummy bypass cell in the same union position or fitting. Ensure plumbing orientation and flow direction match the original. After installation, run the system and verify water flows through without issues and that the salt-cell has been bypassed appropriately.
Maintenance Tips
- Use during off-season or when the salt-cell is taken out of service long-term.
- Check the bypass cell for cracks or wear before re-installing the original salt cell.
- Ensure that the original salt cell and system components are cleaned and maintained before reinstalling and resuming full chlorination operation.
