I just had a backwash valve installed(push pull type) on my Pentair Quad DE filter, my question is- Is it normal to hear a bubbling/gurgling sound coming from the filter after the filter has been shut off?
I did not hear this sound before the valve was installed and just wanted to get advice whether this was normal or is there a problem. The sound is similar to when you put a water jug on an office water dispenser.
