You've probably heard that a new Colorado law takes effect in September 2016 that will require all new toilet installations in Colorado be certified water efficient and meet federal WaterSense
standards. WaterSense certification provides that plumbing fixtures use at least 20 percent less water. For toilets, that means using 1.28 gallons of water or less per flush, as opposed to the federally mandated maximum of 1.6 gallons per flush.
While low-flow toilets will save up to 13 billion gallons a year in Colorado alone, they can also present a few problems. With less water to flush with, you may find yourself flushing more than once because of the low flushing power. This of course defeats the purpose of having a low flow toilet and should be avoided.
Sometimes the problem is caused by an under filled toilet tank. Check the manufacturer's instructions for setting the fill valve to ensure the water in the tank is at the right level. Many tanks will have a fill line to help, if there is no line, a good rule of thumb is to keep the water level about a half inch below the top of the overflow tube inside the tank.
Second, open the tank and adjust the tension on the flapper chain. The chain should only have a little slack, if it's too loose the flapper won't open all the way when the toilet is flushed and water in the tank won't empty completely.
