There is a pink slime or growth in my toilet or shower. Is this caused by my water?: No. Certain species of airborne bacteria gravitate towards and thrive in a moist environment, such as showers, toilet bowls, sink drains, tiles, and dog dishes. These slimes are naturally occurring and can be unattractive but are generally harmless. The best way to avoid this problem is to keep these surfaces free from the bacterial film through regular cleaning using Lysol or a chlorine-based product.

11. Can I taste or smell chlorine in my water?: Some people are more sensitive than others to the smell or taste of chlorine and may become aware of occasional changes in chlorine levels in their tap water. For example, the taste of chlorine may be more noticeable at times of day when water use is high. This is because the water is reaching you quicker and contains more chlorine than when it has been standing in the pipes. Levels of chlorine may also become more noticeable if we’ve been working on the water mains.
