General Water Concerns

Bypass Water Softener
Discolored Water

Slight discoloration in your water can occur from time to time. Your water is safe. The City’s water quality information is provided in the annual Consumer Confidence Report.

  • Black particles – degraded rubber gaskets, o-rings, or meter washers. Check faucet head and replace o-ring.
  • Brown water – possibly caused by nearby construction, hydrant flushing, or manganese in the water supply. Call 512-218-5555 to flush the hydrants.
  • Cloudy or Milky water – air bubbles from air in the pipes or a temperature change.
  • Yellow water – manganese or resin from a water softener.
No Water

Verify the status of your account with Utility Billing. If your account is current, your water may be off due to any of the following occurring in or around your neighborhood:

  1. Water main break*
  2. Construction*
  3. Blockage in water softener line
  4. Frozen pipes
*If water is shut off due to unforeseen circumstances, as a precaution, you may receive a boil water notice from the City. See Boil Water Notice to learn more.
Shut off Water You can shut your water off at the meter by turning the private wheel valve located inside your meter box.  You can also call 512-218-5555 and a City crewmember will assist at no cost to you.
Water Hardness The average water hardness in Round Rock is 221 mg/L or approximately 12.9 grains per gallon. To learn more, visit Water Quality.
Water Leak
Detect Leak:
The first place to detect a leak is at the water meter outside.
  1. Make sure no water is running inside or outside (washers are off, etc.)
  2. Go outside to your meter box and open the lid. Where’s my meter box?
  1. Watch the face of the meter for several minutes to see if there’s movement.
    • The top middle section of the meter will show an arrow to indicate water is flowing through the meter.  If no arrow appears, there’s no water moving through the meter, so no leak. Sometimes toilets leak slowly, then fill up suddenly, so make sure to watch the dial for several minutes.
    • If the arrow is there, you’ve got a leak.

You can check the meter yourself for any indication of leaks, or call 512-218-5555 to request your meter be checked.

Determine Leak Location:
  • Toilets – Drop dye tablets (request free dye tablets) or a little food coloring into the toilet tank and if the color appears in the toilet bowl, you probably have a leaking flapper. Flappers are inexpensive and can be purchased at your local hardware store. Here’s a video on how to check your toilet for a leak.
  • Faucets – Examine faucet gaskets and pipes under the sinks in your house. Old and worn faucet washers and gaskets frequently cause leaks in faucets. YouTube has numerous video tutorials on how to fix a dripping faucet.
  • Showerheads – Some leaky showerheads can be fixed by making sure they’re screwed in tight and by using pipe tape to secure it. For more complicated valve leaks in showers, contact a licensed plumber.
  • Irrigation System – Look for soggy areas around your foundation and irrigation system. Schedule a free irrigation system evaluation (City of Round Rock water customers only) by emailing Water Conservation or call Jessica Woods at 512-671-2872.
Water Meter
Locate Water Meter:

The meter box is usually located near the curb with a metal or black plastic, rectangular lid. There are often two meters inside, yours and your neighbors, yours is the one closest to your property.

Check Consumption:
  • Once you’ve located your meter box, open the lid to read your water meter. Record the numbers.
  • After 20 minutes, repeat the first step.
  • Subtract the first water meter reading from the second to determine the consumption
Water Pressure
High Water Pressure:

The water pressure can be adjusted by accessing the pressure-regulating valve (PRV). PRV’s can be set to 75 psi or lower. If you need help locating the PRV, you can contact our office at 512-218-5555 and we will gladly assist. Please note that we are unable to adjust or replace the PRV; however, we will help you locate it.

Low Water Pressure:

The minimum water pressure allowed by the state is 35 psi (pounds per square inch). The City’s goal is to achieve a minimum of 50 psi at every meter.

  • If you have a water softener, put it in bypass then see if you have water pressure. You can also check your hose bib outside, if there’s water at the hose bib and no water inside, the problem is most likely with your water softener.
  • If you do not have a water softener you can contact our office at 512-218-5555.
