Thanks for the reply spa guru, Unfortunately the CC is not the issue as i havnt tried it on another pool, but have tried another Creepy crawly on my pool with the same results. As for the vacuum release, when i originally connected it the suction was way too high so i drilled some holes in the skimmer box adapter to allow some water to bypass. The cavitation slowly got a little better so i kept drilling and eventually drilled too much that the CC stopped all together. However pump was still cavitating. It makes me think it is a pressure problem somewhere in the system. Maybe pump too large or possibly too small?

Hi guys, I have just bought a house with a concrete in ground pool. It is a large pool at roughly 13x8 meters. The pump has been running with no problems since we moved in 2 weeks ago. A couple of days ago I got given a new creepy crawly. It's a zodiac t3 and hardly been used. When I plug it in the pump starts to moan and the filter with the clear lid attached to the pump starts to fill with air. I make sure there is no air in the cc hose when it's put into the pool. I have tried the neighbours cc too and same story. I thought maybe the pump was drawing too much so I drilled some holes in the skimmer fitting but as the air slowed, the cc stopped all together. With the flow monitor only reading 1.5. Today I tried the cc attached with the filter set to rinse and this seemed to work fine. I have come to a brick wall so some help would be much appreciated.
