    Knob on backwash valve

    The valve on my pentair backwash valve broke as I was trying to open it. Is this something that happens often, should I have been living that handle. It's only an year old.
    I was looking for the part, looks like I can replace the handle without having to change the whole insider part, or do you all recommend changing the whole inside.

    Thanks, jr

    Opened it up, sure enough there was a piece of pvc glue at the very bottm of valve that was probably making it difficult to open everytime i had to back wash until it broke.

    Good for you to open it up and explore. That handle is pretty easy to order and replace DIY. Let us know if you need help.
