Installed my FASS Titanium 150 and it sounds to be cavitating I spoke with customer service and they told me to do a bucket test but I'm not sure what the problem would be if the bucket test works. Should I just install a sump?
I've installed dozens of them over the last few years and have never had one that was defective. I have only heard of a small amount of them being defective and only here on this Forum so far.
