Q: I purchased an EC40 DE filter. I took it apart to clean it in the middle was a tall tube with the check valve. How do I place this back in the tank??? Does it connect to something and which way do I place it in the tank. Does the open side with the valve face towards the incoming water or the drain side??? And how do I keep it standing up when I place the top back on with the fingers??? I’ve called a couple company’s but they know nothing about this filter. They were numbers your company gave me! Please I need some help. Single lady so I do everything myself.
