Leak Detection

Household Leak Detection

Water leaks can waste a lot of water and cause outrageous utility bills. Check for leaks around the home by reading your water meter and inspecting your toilet, faucets, showerhead, and even irrigation system. 

Fix A Leak Week 2018
Fix A Leak Week is a national annual event held by EPA WaterSense to encourage water consumers to find and fix household water leaks to save water, energy, and potentially even money on utility bills. This year, Fix A Leak Week is March 19-25, 2018. Celebrate Fix A Leak Week by being a leak detective and checking for leaks in the kitchen, bathroom, laundry room, basement, and even outside. Most leaks are easy to fix, such as a dripping faucet or running toilet. Finding and fixing leaks is simple! Inspect fixtures, twist and tighten connections, and replace if necessary with WaterSense labeled models to save at least 20% more water without sacrificing performance. 

Royal Leak Detection

Royal Leak Detection Contest

In celebration of EPA WaterSense's Fix A Leak Week, we are holding a Royal Leak Detection contest. One lucky Concord resident will win a free new "thone" (WaterSense labeled toilet) if entered by 5:00 p.m. on Friday, March 23, 2018. WaterSense labeled products are certified to use at least 20% less water, save energy, and perform as well (or better than) regular models. Enter for a chance to win by sharing with us how you find and fix water leaks! Scroll down below for some ideas on how to find water leaks in the home!

Enter one of two ways (or enter both ways to double your chance to win):

Water leaks can be a royal pain! A leaky faucet, toilet, showerhead, or irrigation system may seem harmless, but more than 10,000 gallons of water are wasted each year from leaks in the average household. Leaks can also cause an increase in utility bills from more water usage. Find and fix leaks to save water, energy, and potentially even money on utility bills! View our official contest rules for full terms and conditions.

Be A Leak Detective

There are many ways you can be a leak detective:

Check all fixture connections and see if any water is leaking through. Sometimes tightening is all that is needed. Consider adding an aerator (a twist on screen that adds air into the water stream) to your faucets to save water, without sacrificing the water pressure.

Many toilet leaks are caused from the flapper being broken or decayed. The flapper is the piece of rubber that is attached to the toilet handle that allows the water to flow into the toilet bowl from the tank after flushing. A quick flapper replacement should do the trick! Another common toilet leak is water flowing down the overflow tube. If this is the case, lower the water level in the tank to save water and reduce utility costs. If you can hear the toilet running, then that is a sure way to tell if you have a leak. You can still have a leak, even if you don't hear your toilet running! If your flapper looks fine and there is no water going down the overflow tube, a good way to test for a leaky toilet if your is to perform a dye test. Simply place dye into your toilet tank (do not flush) and wait for approximately 30 minutes to see if the water in the bowl changes to the dye color. If it does, then water is leaking from the tank. Be sure to flush after the test to remove the dye. Most toilet repairs are easy fixes and parts can be easily found at local hardware stores. Consider upgrading to a WaterSense labeled toilet to reduce your water use by 20-60%! Older toilets use as much as 6 gallons of water per flush, while newer water efficient toilets, such as WaterSense labeled models, use closer to 1.3 gallons per flush, while still providing equal or superior performance!

Toilet Leak Dye Test Kits
Toilet Leak Dye Test Kits are available at our water billing window at 311 North State Street. Come grab your free material to perform a quick and easy leak test on our toilet! Hurry in while supplies last! Materials will only be on display through the end of March in coordination with our Fix A Leak Week promotion.


Showerheads can also get old and leak. A showerhead that drips 10 drops per minute can waste more than 500 gallons of water per year! Most leaky showers can be fixed by tightening fixture connections. A simple fix would include wrapping the leak with pipe tape, or consider upgrading your showerhead to a WaterSense labeled model to save water and potentially even money off utility costs.

Garden hoses and irrigation systems should be checked regularly, especially after winter to check for damage from frost or freezing. Make sure connections are tight. Pipe tape can be used for a quick solution to wrapping up any leaks. 

Most repairs are easy fixes and parts can easily be found at a local hardware store, but contact a licensed plumber if additional help is needed. Visit our WaterSense webpage for more information about EPA WaterSense and ways to conserve water.

City Leak Detection

Our crews continually work at fire hydrants and valves to find any potential water leaks throughout Concord. Finding hidden leaks helps to conserve water, which prevents the waste of City treated water and reduces the efforts and costs of excessive pumping. Water service will not be interrupted unless a leak is found. Notice will be given if a leak is found before repair. The City of Concord is not responsible for leaks found within private property.
