Backyard Aquaponics
A place to discuss aquaponics

Hello, does anyone knows why an index valve will not rotate from bed to bed correctly? . Mine tends to go to the same bed over and over until I change it manually or it will go to all the 5 beds at the same time. I have the index valve on a timer 12 minutes on and 10 minutes off. (This problem started about a year ago, our aquaponic is 8 years old)
