Installation
Installing the Tier1 Pool & Spa Filter Cartridge is a straightforward process. This cartridge is designed to fit systems that utilize an 8 1/2 inch (Outside diameter) x 23 1/8 inch (Length) spa or pool filter. It is engineered to fit and perform comparably to original equipment manufacturer products.
Before installation, ensure your pump system is turned off and depressurized. Refer to your pool or spa system's specific manual for detailed instructions on how to access and remove the old filter cartridge. Once the old cartridge is removed, carefully insert the new Tier1 filter, ensuring it is seated correctly within the filter housing. Secure the housing according to your system's guidelines and then repressurize the system.
Operation
The Tier1 filter cartridge operates by efficiently sifting out unwanted particles from your pool or spa water. Its pleated fabric design, featuring tight porosity and a dense weave, effectively captures sand, debris, leaves, hair, and sediment. The high strength, high flow design ensures optimal water circulation while maximizing filtration.

The filter's advanced design, including an injected molded core, contributes to strong, reliable construction, superior water flow, and uniform sediment distribution. This helps reduce stress on your pump, contributing to the longevity of your pool or spa system.

Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your Tier1 filter cartridge. It is recommended to clean your filter when the pressure gauge on your filter tank reaches 8 psi above the pressure recorded when the filter was first installed. This indicates that the filter is accumulating debris and requires cleaning.
The filter's superior cleanability is due to its uniform fabric, which reduces clogs and is easier to clean. It utilizes 100% of the filter's surface area for maximum efficiency, and its sturdy, evenly spaced pleats hold up to multiple cleanings without wear.

To clean the filter, remove it from the housing and rinse thoroughly with a garden hose, paying attention to the pleats. For deeper cleaning, specialized filter cleaning solutions can be used. Ensure the filter is completely clean before reinstalling. The lifespan of the filter is approximately 3 months, but this can vary based on usage and water conditions. Regular cleaning will help extend its effective life.
Troubleshooting
If you experience issues with your pool or spa filtration, consider the following common troubleshooting steps:
- Reduced Water Flow: This often indicates a clogged filter. Perform a thorough cleaning of the filter cartridge as described in the Maintenance section.
- Cloudy Water: If water remains cloudy after chemical treatment, the filter may not be effectively removing particles. Check if the filter needs cleaning or replacement. Ensure proper installation and that there are no bypasses in the system.
- Short Filter Lifespan: If the filter requires frequent cleaning or replacement, it might be due to heavy usage, high debris load, or improper water chemistry. Ensure regular water testing and balancing.
If problems persist after following these steps, consult a qualified pool or spa technician.
