If I had a dime for every customer who proudly told me they put vinegar in their heads, & flushed it with fresh water, in order to prevent calcium building up in the sanitation hoses, I'd be retired now.


The truth is, despite their best efforts, I still find the sanitation hoses plugged & occluded with calcium build up.


Yesterday was one of those days. I hate these jobs and don't technically do them but for good customers I will occasionally make exceptions. In this case the customers hose was plugged with calcium and they had used vinegar religiously to prevent just such a situation.


As an experiment I dropped the head outlet elbow into straight vinegar and left it there to see if there was any change. I had done this before but never took pictures or placed the time in the vinegar into the photo..
