Detecting Water Leaks
How to Detect a Water Leak
If you suspect a water leak, turn off all the faucets in the house. Check your water meter to see if the flow detector (a small red or black marker) is moving.
If the flow detector moves, then stops, then moves again, it is a good indication that your toilet valve is leaking or that there may be a very small leak.
If the flow detector moves slowly, it is a good indication that you have a small leak.
If the flow detector moves rapidly, it is a good indication that you have a break in your line - check for soggy areas in your yard or under your house.
Your toilet may have a silent leak. Drop a little food coloring into the tank. Wait about 10 minutes without flushing. If color appears in the bowl, you have a leak.
Check for moist spots around and under the house plumbing and around outdoor plumbing.
Replace worn washers in faucets and showerheads. Even a small drip can waste as much as 170 gallons of water each day, or 5,000 gallons per month.
Possible Toilet Leak Sources
The flapper valve and valve seat (A) have deteriorated or corroded.
The flushing arm and lift chain (B) are not working properly.
The water level in the tank is too high and spills into the overflow tube (C).
The float rod, ballcock and / or float ball (D) are corroded.
Water leaks are costly. A “typical” toilet leak at today’s rates can add three hundred dollars ($300) to a single water bill. Our information is provided as a courtesy with hopes of action on your part, which may minimize an unnecessary waste of water and expense to you.
