just bought a house. First pool.
It has an old Jacuzzi FM... must be 25 years-old. But every pool guy tell me it's as good as a new machine.

I'm also not very good with all the terms for the machinery I have so forgive me.

Sometimes when I vacuum... especially if the vacuum meets some resistance like when it sucks real well at the bottom of the pool, it will stop working. No more sucking action... no more jet in the pool. Then I unplug the vacuum from the skimmer (I have one skimmer and one jet in the inground pool) and after a minute or so, everything starts again.

Now, that wasn't to bad but I bought a barracuda. When I plug it in the skimmer, it will work for max 15 seconds before it stops sucking and before the jet stops.

Also, when I vacuum, a lot of bubbles come out the jet.

I thought about air infiltration. I changed the rubber ring thing inside what must be called the pump... the small engine near my filter. Although the original ring was cracked, the new one didn't help.

thanks for any help you might have
