What causes most leaks?
• Toilet flappers are one of the most common causes of high bills. When the rubber starts to warp and does not make a good seal on the seat ring, the water in the tank slowly drains which causes the fill valve float to fall and refill the tank. • Pin hole leak in PVC line going to the house. A hole size of a 1/16″ in diameter leaking 24/7 will lose 24,600 gallons in a month.
