How Does a Pressure-Reducing Valve Work
If you are looking near the main shut-off valve in your home (which we sure happens frequently) and notice a cone-shaped valve near it, you may ask yourself, “What could that be”? The answer may (or may not) surprise you. That cone-shaped valve is called a Pressure pressure-reducing valve (PRV), and it is sometimes necessary to control the water volume in your home. They are small, relatively inexpensive valves typically located near your water meter.
Does a PRV reduce my sinus pressure? What about the pressure from my job?
Unfortunately, your PRV does neither. Although it does control the water pressure in your home, it is comfortable to use and keeps your water bill under control. It can help conserve energy consumed within your home, save you money on maintenance of the other plumbing in your home, and reduce your monthly bills.
If you hear banging pipes in your home or water appears to be gushing from an open tap, you probably have excessive water pressure. If your home has low water pressure, you may also need to replace your PRV. You can also get your water pressure tested by a plumber or your water company.
Does my PRV last a lifetime?
Your PRV will last approximately ten years under regular use. We recommend replacing it after ten years to prevent it from going out, which can cost you more than just a headache. When a PRV goes bad, it can cause your home to have immediate excess or decrease in water pressure, which can be very symptomatic. Symptoms include banging pipes, no/intermittent water, and/or the valve can begin leaking.
