How do Pentair OEM pool products compare to Non-OEM Pentair pool products?

Pentair OEM pool products meet exact Pentair specifications. As a result, they provide reliable fit and consistent performance. Additionally, materials and quality control meet strict Pentair standards. They offer dependable operation and lasting system integrity.

Non-OEM products cost less. However, material quality and manufacturing precision vary. Compatibility with Pentair systems is not guaranteed. Lifespan and performance may be reduced. Overall, OEM components deliver quality, while non-OEM products, deliver uncertainty.
