Dear Valued Customer:
Clarksville Gas and Water Department contractors will be in your area very soon replacing existing water mains to accommodate the road widening project on US41A/Madison St. As part of this project, Clarksville Gas and Water contractors will replace and reconnect your service line from the new water main to your new water meter and meter setter. The new replacement setter includes a check valve (backflow preventer).
When a backflow prevention device is placed on a water service line, the water that has been delivered through the customer's meter is prevented from returning through the meter to the water main, thereby preventing potential contamination of the water supply by cross connections. This creates a closed loop system within the customer's water system. This condition may result in a condition to the customer’s internal plumbing that is called “Thermal Expansion”.
What is Thermal Expansion?
Thermal expansion is an increase in water pressure due to heated water having nowhere to go in a closed system. When hot water is used it is replaced in the water heater with cold water. As the cold water is heated in the water heater it expands.
The closed system leaves little or no space for expansion. The result is a potential increase in water pressure that may damage water heaters, plumbing systems and fixtures.
What can be done about thermal expansion?
There are signs to look for to identify potential problems before more serious ones occur. Please learn the signs of thermal expansion from the list below.
Some signs of thermal expansion
The relief valve on the water heater drips during the recovery cycle. Hot water pipes make a creaking sound.
There is a sudden surge of water when a faucet is first turned on, then the pressure drops.
Premature failure of water heaters, plumbing and fixtures.
Hot water in the cold water lines.
It is important to know that the water heater relief valve should not be used as a means of controlling thermal expansion. Instead, contact a plumbing professional if you suspect a problem. The plumber can schedule an inspection and install proper thermal expansion control methods.
Current plumbing codes require the installation of thermal expansion relief devices in "closed systems". The two most common methods are to install either an expansion tank, or a thermal device installed on the cold water line to the tank. We suggest you discuss the best solution for your needs with a licensed plumber.

12 MARCH 2014 Underground Utility Line Locating and Markings on Madison Street (U.S. Highway 41A)
CLARKSVILLE, TENN. - Clarksville Gas and Water utility line locators have been working diligently to locate and mark underground utility lines along Madison Street, including several side streets, from Richview Road to just east of McAdoo Creek Road for upcoming utility line relocation work. The line relocations are in conjunction with the Tennessee Department of Transportation road widening of U.S. Highway 41A between State Route 76 and McAdoo Creek Road.
The utility line relocation work phase is targeted to begin this spring and is estimated to be finished by mid-year 2015; however, utility line locating and marking will continue throughout both the line relocation work and the entire highway widening construction project.
Underground utility lines are marked with color coded paint lines, stakes or flags which should not be removed. Removing the markings can result in punishment for vandalism under the Tennessee Underground Utility Damage Prevention Act, Tennessee Code Annotated §65-31-101, §65-31-112.
It is imperative the line location markers remain in place to alert digging and excavation crews of the line locations to help avoid damaging the lines. Damaged lines can lead to personal injury, inconvenient outages, costly repairs and delays of the scheduled work.
Motorists traveling through the work zone are asked to slow down, obey posted traffic signs and be alert of workers as they perform the important job of marking utility lines along right-of-ways for your safety.
