FREE Rain and Freeze Sensors:Rain and freeze sensors are a great addition to any automatic irrigation system. When temperatures are near freezing or when we have had substantial rain, the sensor overrides the controller and temporarily turns it off. When temperatures rise again or when the rain has stopped and things dry out a bit, the sensor releases the controller back to its regular programming mode. While supplies last, the City of Carrollton Water Utilities provides free rain and freeze sensors to all water customers for the purpose of retrofitting an automatic irrigation system. Systems must have been installed prior to January 1, 2006. The free devices are limited to one per residential or commercial premise and customers will be responsible for installation of the device. Requests for the free Rain and Freeze sensors must be made in person at Utility Customer Service, 1st floor of City Hall, 1945 E. Jackson Road, Monday through Thursday 7:30 a.m. to 5:30 p.m., and Friday 7:30 a.m. to 11:30 a.m. For more information call 972-466-3000.
This program offers a rebate to commercial, industrial, and institutional water customers for up to half the purchase price of water-saving equipment with a $5,000 maximum. Project must be installed after January 1, 2006 and not be related to landscape irrigation. Rebates are awarded based on a review and approval process. If you are interested in participating in the ICI Rebate Program, call the Water Utilities department at 972-466-3000.
Free Pressure Reducing Valve (PRV) Program (Residential Program)The City of Carrollton offers free pressure reducing valves (PRV) to residents with water pressure above 95 psi. A PRV is a device that is installed after the water meter to reduce the amount of pressure coming into your home. The PRV has the ability to reduce water consumption up to 30%.
To receive free PRV...
- Call the City of Carrollton at 972 466-3425 to confirm that your address qualifies for the program and request a Pressure Reducing Valve (PRV).
- Once you have initial approval, you must take your identification (or most recent water bill) to the Building Inspections department at city hall. You will need to fill out a Building Inspection Permit Application and the Free PRV Program Application. There is no fee for this permit.
- Once the forms are filled out and you receive your permit at the Building Inspection department, take them to the Utility Customer Service counter (which is just across the lobby from Building Inspections). Once the Utility Customer Service representative has reviewed your paperwork, you will receive the free PRV (only one PRV per resident).
- It is your responsibility to get the PRV installed onto the service line to your property. As the homeowner, you are authorized to install the PRV yourself HOWEVER, if you are not experienced with plumbing repairs or installations, it is best to find a licensed plumber to install the PRV. You can find licensed plumbers through local advertising, referrals from people that you know or from the Texas State Board of Plumbing Examiners (TSBPE) http://www.tsbpe.state.tx.us/consumer-information.html
Frequently Asked Questions about Pressure Reducing Valves (PRV)
What is a Pressure Reducing Valve?
Pressure Reducing Valves or PRV’s are used in residential, commercial and industrial applications to decrease incoming water pressure which reduces water consumption.
How does it work?
Pressure reducing valves reduce the pressure of the incoming water. They are made out of sturdy material, such as brass, to withstand the constant force of water pressure. They can be adjusted to regulate the outgoing pressure from 20 to 80 psi and are factory set at 50 psi.
Where are Water Pressure Regulators installed?
Water pressure regulators are commonly installed on the downstream side of the meter in residential, commercial and industrial buildings. This location is desirable because it controls the water pressure flowing to all appliances and faucets in the building.
What is the difference in water flow from a fixture when the pressure is at 100 psi vs. a pressure of 50 psi?
Reducing the pressure from 100 psi to 50 psi will result in a savings of approximately 1/3 because 1/3 less water flows at this lower pressure. Remember, there is more "push" behind the water at 100 psi than at 50 psi and most of this water is wasted. A moderate savings would result if your supply pressure was reduced to 65 psi however, even at this lower pressure, savings with a regulator would be about 20%.
Are there any studies to support this savings figure?
Yes. In 1971 the Washington Suburban Sanitary Commission conducted a test program in 2,400 dwelling units that has attracted widespread interest from more than 40 states and various foreign countries. One of the devices used in their conservation study was a water pressure regulator. It is interesting to note that their report concluded that in test locations using regulators, they found that water consumption was reduced by 30% in October and November and 37% in December.
How do I know if I have high water pressure? If you suspect you have high water pressure you may call the Resolution Center at 972-466-3200 for assistance and additional information.
