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.
Pro Tips: Pentair 98209800 High Flow Air Relief Valve
- If you notice your valve is leaking or becomes difficult to open, make sure to check the surrounding O-ring and the threaded hole on the lid.
- Sometimes replacing the air relief valve will not fix the problem. Especially, when there is damage to the threaded hole on the lid. Be sure to shut off the pump and relieve filter pressure before working on the air relief valve.
- Once you have installed the air relief and the pump is running. Always make sure to open the air relief and allow any trapped air to release. There should be a steady flow of water going to the filter, then turn off the valve.
