How to: Avoid build-up

July 3rd, 2009

ThoseNastyRings2Villa owner Mark Tillack asks how to avoid the build-up of urine sediments around the drain. He has a 2002-era Villa. He attaches this photo. 

Answer: Pour water–preferably hot–with some vinegar down your urine drain periodically to break up any urine sludge that builds up. Urine sludge is common even in urinals. It is the minerals in your urine adhering to the walls of the pipe. 

The best way to avoid it is to:

1. Make sure your urine drain is sloped as much as possible.

2. Flush the urine drain periodically with water and vinegar. The vinegar’s acid will break the bonds of the salts and minerals. 

Note: Tap water, especially if it is from a well, can have a high mineral content. This can react with the urine minerals to create a hardened sludge that gradually constricts the pipe. (Again, this is common in waterflush urinals.) Flushing your urine drain regularly with cold well water and no acid (vinegar, citrus juice, etc.) can contribute to this constriction, especially if there is little slope in the drain line.
