Pressure Reducing Valve Replacement in Orlando & Central Florida

A pressure reducing valve (PRV) is a brass fitting installed on your main water supply line that reduces and regulates the incoming municipal water pressure to a safe level — typically between 50 and 70 PSI — before it reaches your pipes and fixtures. Without one, the full force of city water pressure (often 80–150 PSI) would enter your home, stressing every pipe joint, appliance, and fixture in the system. Most homes in Central Florida served by municipal water have a PRV installed as a code requirement.

The most common signs are noticeably low or inconsistent water pressure throughout the home, banging or hammering pipes when you close a faucet, visible corrosion or moisture around the valve, or a pressure gauge reading outside the normal 40–80 PSI range. In some cases a failing PRV fails open, allowing dangerously high pressure — which stresses fixtures and appliances without an obvious symptom until something breaks. If you suspect a problem, a Lapin technician can test your pressure and inspect the valve during a service visit.

Most PRVs have a service life of 10 to 15 years under normal conditions. Hard water with high mineral content — common in Central Florida — can shorten that lifespan by accelerating buildup on the internal diaphragm and seat. If your valve is 10 years or older, it’s worth having it tested even if you haven’t noticed any obvious pressure changes yet.

PRV replacement involves shutting off your main water supply, cutting into the supply line, soldering or threading in the new valve, and calibrating the pressure to the correct set point — typically using a pressure gauge and the adjustment screw on the valve. While a skilled DIYer could attempt this, an improperly installed or incorrectly calibrated PRV can either allow damaging high pressure to pass through or restrict flow too far. Given the potential for water damage or appliance failure, most homeowners prefer to have a licensed plumber handle the job correctly the first time.

The Uniform Plumbing Code recommends household water pressure between 40 and 80 PSI, with most plumbers targeting 50 to 60 PSI as an ideal range for everyday comfort and appliance longevity. Pressure below 40 PSI can make showers and fixtures feel weak; pressure above 80 PSI accelerates wear on washers, seals, and appliance inlets. After installing a new PRV, Lapin technicians calibrate the valve and confirm your pressure falls within the recommended range before leaving the job.

In many cases, yes. When a PRV is installed, it creates a closed plumbing system — meaning water heated by your water heater has nowhere to expand back into the supply line. This thermal expansion can cause your water heater’s relief valve to drip or fail prematurely. An expansion tank absorbs that pressure increase and protects the system. Many Florida municipalities and building codes now require expansion tanks on closed systems. Our technicians will assess your setup and let you know whether one is needed during your PRV service.

For most homes, pressure reducing valve replacement is a straightforward job that a licensed plumber can complete in one to two hours. Time can vary depending on the valve’s location, the type of pipe it’s connected to, and whether any additional work — such as an expansion tank installation or supply line repair — is needed at the same time. We’ll give you a clear timeline and price before any work begins.
