Maintenance Tips
- Clean cartridges when pressure rises about 8–10 PSI above your clean starting pressure (or when flow drops).
- Rinse between pleats from top to bottom and rotate the cartridge as you clean for a more thorough rinse.
- Deep clean periodically to remove oils; if scale is present, degrease first, then treat for scale and rinse thoroughly.
- Inspect and lightly lubricate tank O-rings during service to help maintain a consistent seal and prevent air leaks.
