Due to "howling" in our plumbing on the last visit the plumber attached a pressure "meter/reader" to our house and asked what the city's water pressure is. They are checking to see if high water pressure or water pressure spikes may be creating the howling.

What is the pressure the city expects at a residence? Ours hovers between 90-112.

Based on location, time of day, and elevation, the water pressure in Frisco can vary from 50 pounds per square inch (psi) to 120 psi. The minimum operating pressure required by the State of Texas is 35 psi. Please send me your street address at so we can check the actual pressure on your street. Also, homes constructed after 2001 were installed with a pressure regulating device. Your device may need to be adjusted or a pressure device could be installed by a plumber. Thanks.

I had a plumber tell me today that the water pressure coming into my house was 100 psi and it should be operating between 60-80 psi. I have a leaking water heater pressure relief valve and he said that the high water pressure was the cause of the leak and I should install a pressure regulating device.

My house was built in 2005 and should already have one installed. How can I tell if one has already been installed. Any help would be greatly appreciated.

Thank you

Pressure reducing valves have been required on all new homes since 2001. They are typically located in a valve box adjacent to the main shut off valve where the water supply enters the home. These devices require periodic maintenance to perform properly. Plumbing Inspection staff can assist in locating your PRV if needed. Contact us at 972 292-5301 or
