Hello! I was changing the filters for the first time on my Aquasana AQ-5200 2-stage under counter carbon filters when I discovered a rather large amount (nearly a tablespoon) of white waxy, grease like build-up on the inside of each filter stage housing, pushed into the threads, and on the outside of the filter itself. I installed the filter system myself and did not use any sort silicon grease etc.
The substance is almost pure white, resists water, does not dissolve or melt in hot water or vinegar. Bringing a flame to the substance dries it out, chars the edges black and dries it to a soft powdery consistency. It does catch aflame eventually and burns a low blue / yellow typical looking flame.
Our water supply is municipal, city water and it's seemingly very hard with mineral buildup on many of the fixtures. Boiling water always results in minerals precipitating out.
I could not find any info on such an occurrence here or anywhere else online. What could this substance be, and should I be concerned?
Thanks for your time.
