SERVICE TIP
Checking for water leaks behind or under toilets or other appliances can make it difficult to locate the source. Dripping
water at room temperature makes it difficult to feel wetness. Taking four or five sheets of toilet tissue and wiping all
seams and waterline connections offers a simple means of locating the general area of the leakage. Start at the top of
the unit since gravity will cause a leak to run downward. When the tissue comes in contact with the leaking water, it will
immediately change texture.
