This evening, I came home to find my room flooded and the carpet all wet. It turns out the "double tap" valve on my Eheim Pro II 2026 was broken, so the filter was siphoning the water from the tank onto the floor. I bought my Eheim Pro II back in 2004. It has served me well these last 8 years. Eheim's official website sells a replacement valve for $42. Given the filter's age, should I try replacing the part or should I dump it for a new Eheim Pro III?
