Excess grease should never be poured down the drain. In addition, fat from greasy foods, such as bacon, should be wiped off the dishes before they are put in the dishwasher. On occasional use of hot boiling water or a good commercial cleaner will help to keep your house drain line clean and free of trouble. Use fabric soaked in hot water to thaw the pipes. An open flame on frozen pipes could lead to a steam explosion or a fire hazard.
Defective toilets can cause the greatest amount of water loss.
The two most common causes of leakage are a defective supply valve or improper seating of the rubber tank ball. Leakage can be detected by placing food coloring in the toilet tank at night. If, in the morning, food coloring is visible in the bowl, you have a leak. Repairs can be done by a licensed plumber. This is the responsibility of the property owner.
