Always cross-reference your filter’s model number and the part number before ordering to ensure a correct fit. It is not intended for smaller Berlin filter diameters (\u00d8500\u2013\u00d8750 mm) or other filter ranges.<\/p>\n
As a genuine Fluidra OEM part, this drain plug is manufactured to the exact tolerances of the original, ensuring a pressure-tight seal and reliable operation under normal pool filtration working pressures. Aftermarket alternatives may not match the thread pitch or material specification of the Berlin filter body, risking leaks or damage to the tank fitting. Choosing genuine protects your filter’s integrity and warranty status.<\/p>\n
The drain plug threads directly into the dedicated drain port at the base of the Berlin \u00d8900 filter tank. Always relieve system pressure and isolate the filter from the pump before removal or installation. Use PTFE thread tape on the threads to ensure a watertight seal, and do not overtighten. Professional installation is recommended if you are unfamiliar with pressurised pool filtration systems.<\/p>","protected":false},"excerpt":{"rendered":"
