Air returning from pump reducing pressure

[neil.gould]

Hi
Hope someone can help
We have a sand filter system and a pump
I have air coming from my pool pump blowing air bubbles back with the water so the cleaning vacuum won't work?
Any ideas it started doing it a week ago
Thanks
Neil

Is the O-Ring on the lid of your pump worn or missing? the problem would be somewhere on the suction line from your skimmer, vacuum port, or pipe work. Also, is there any abnormal dirt showing up in your filter or blowing back into the pool via returns? More than likely, it would be something as simple as the O-Ring.

Thanks for your reply, Ill have a go at changing them, no returning dirt just bubbles
Thanks

If you are replacing the o-ring, make sure you use a good teflon o-ring lubricant such as aladdin's or lube-tube
