Pentair System 3 Modular Media Filter S8M500 Replacement Cartridge Pack | 170148
Couldn't load pickup availability
Pentair System 3 modular media filters use balanced-flow hydraulics for consistent performance, and while tanks carry warranty coverage, cartridges like this pack are considered consumables and are not typically covered.
Q: How often should I replace these cartridges? A: Inspect annually; replace when media shows signs of wear, tearing, or when backwash doesn’t restore flow. Q: Can I use just one cartridge instead of full pack? A: Using only one module may unbalance flow and reduce efficiency. It’s best to replace both together.
