Review on Aquasana Brushed 3 Stage Filter System: Superior Water Filtration for a Cleaner, Safer Home by Marcus Barlow

I bought an Aquasana AQ-5300+.55 3 stage filter for about $182 + tax. The filter leaks immediately after installation. This is a slow but constant dripping from the 2nd stage port to the manifold (housing), see photo/video, not sure if it's an o-ring or something else. You can't "tighten" or change this connection since it's a fast connection, so I'm out of luck. This is unacceptable quality control for a $200 product and means they are unlikely to test these devices before shipping. I cannot trust this company/product to replace or guarantee this unit as it will be a $10,000 water damage bill if it breaks while I am not there. Otherwise the water would be delicious. The flow rate was as stated, approximately one gallon per minute. Installation was easy enough if my large sink didn't limit access. The tee is metal which is nice. However, the manifold connections are plug-in connections, which I do not trust very much.
