Meet PRV, Your Home's Water Guardian! 🚿✨ These valves keep water pressure in check, ensuring a comfortable and safe home. Although high water pressure is often seen as a positive, most homes should have a maximum PSI of 75. Anything above 75 can be detrimental to your comfort and home. Normal operating pressure is 60-65. This level of water pressure is more comfortable and better suited for your home’s infrastructure.
