Aquael Ultramax Canister Filter Check Valves – Essential Spare Parts
Maintaining your Aquael Ultramax Canister Filter requires the correct spare parts to ensure optimal performance. One crucial component is the Check Valve In and Check Valve Out, which regulate water flow and maintain system efficiency.
Important: Check Your Filter’s Purchase Year!
Before purchasing a replacement check valve, it is essential to determine the year your Ultramax Canister Filter was manufactured. Pre-2021 models and Post-2021 models require different in and out check valves, and using the incorrect part may lead to incompatibility issues.
