Eastern Massachusetts is suffering from a severe drought this summer.  Residents of Concord are currently prohibited from washing cars or watering lawns. To help in the conservation efforts, I decided to tackle a long overdue home maintenance project today.  Three of the four toilets in our house have slow toilet tank leaks (a small trickle of water constantly flowing down the sewer pipe).  Over time I am sure it adds up to significant amount of waste and it also causes the tank valve to cycle throughout the day and night which is very annoying.  It took about 90 minutes to remove, completely rebuild and replace each of the toilet tanks. Not the most pleasant task in the world but well worth the effort.
