I installed a Intex sand filter and saltwater system (CS15110) about 3 weeks ago and it seemed to be working fine. Over the last 4-5 days it has become very loud, almost sounding like a bearing is out in the pump.
The pressure gauge over the sand filter still reads in the green and it is still circulating well, but the noise is a pain.
Obviously I'd rather not replace the pump, but if I need to, then I can.
Thanks for any insight.
