My pump is making a strange sound, approximately every 40-50 seconds. At first I thought something may be jammed in the impeller, but I've cleaned that out as best I could and its still making the noise. I've included a link to the video below, the sound of the pump changes towards the last bit of the video. (I've since emptied the skimmer basket too, just FYI ;-) I have the pump turned off now because I didn't want any damage to occur.
Any ideas? Thanks for your help!
