Find Leaks – Fix Leaks

Use Your Meter to Find Leaks
Did you know that your water meter can help you find a leak? That’s right! Your meter has a handy leak detection dial to help you identify leaks. Go out to your water meter box and remove the lid. Please use caution as the lid can be heavy. Look at your water meter to find a small dial with a triangle (usually blue, black or red in color). This is your leak indicator! This triangle spins whenever water is moving through your meter. If everything is off and the dial is moving then that’s a sign you have a leak.

If you do have a leak, check some of the most common places: toilets, pool fill and irrigation valves. For further assistance or information please contact the Water Resources Team at (951) 736-2234.

Check Your Toilet for Leaks
A leaky toilet can waste between 30 to 500 gallons of water per day! Just because it doesn't make a noise or have water at the base doesn't mean that it's not leaking. Here's a simple way to check to see if your toilet is leaking:

  1. Remove the lid and place a few drops of food dye or toilet dye tabs into the tank.
  2. Wait 15 minutes.
  3. Check the bowl to see if there is food coloring in the bowl. If so, you have a leaky toilet!

Found a Leak?
All is not lost! Often, toilet leaks can be fixed simply by replacing the flapper valve located in the toilet tank. Flapper valves can be purchased at most home improvement stores here in Corona.

Recirculating Pump Rebate

Recirculating PumpThe City of Corona Department of Water and Power is offering a $50 rebate on newly installed recirculating hot water systems.

What is a recirculating hot water system? 
A recirculating hot water system uses a by-pass valve that connects the cold and hot water supply lines at the fixture that is farthest away from the water heater. The by-pass valve uses the cold water line as the return loop back to the water heater, continuously recirculating hot water.
