The most common cause of VorTech noise is a dirty wetside. It's very important to disassemble and clean your wetside and we recommend a full cleaning 4-6 times annually. Regular maintenance will prevent noise or potential damage to your wetside. To clean your wetside, start by soaking the wetside only in a 50/50 mixture of hot water and white vinegar. From there, completely disassemble and clean all components. For more information on disassembling your wetside, please reference the video links below.
