Air bubbles in pump basket

My friend's pool (see below for info) seems to consistently get small, circulating air bubbles in her pump basket. When I put her skimmer shut-off to half for a bit, the basket returns to full with no bubbles. A few hours later, same thing. Is this symptomatic of something?

~15K IG vinyl 1hp pump, Jacuzzi 225L filter

Suction side leak. Could even be the O-Ring on the gasket lid if she's lucky.

Oooh, thanks! I noticed the o-ring looked really dry.I tried to remove it to inspect it, but I couldn't even budge it! Will recommend getting a new one and then scrape away the old one, and replace. Sound like a plan?

As an aside, it's funny. My own o-ring falls out every time I clean the basket. Pain in the patootie! Thank goodness I use skimmer socks!

Yup. It should be soft and pliable.

Put some Pool and Spa Lube on it and it will hold it in place.

Hey. Could one of you hydraulics guys chime in on this thread if you have anything to add? Pool/Spa connection question: http://www.poolforum.com/pf2/showthr...012#post128012 Thanks!!!
