Pressure Reducing Valve Replacement With Clear Answers Before Work Begins
Your pressure reducing valve (PRV) is a small but critical component that controls the water pressure entering your home or business from the municipal supply line. When it's working correctly, you don't notice it — but when it starts to fail, the symptoms are hard to ignore. You might experience sudden drops in water pressure throughout the house, pipes that bang and rattle, water that hammers when faucets are shut off, or dangerously high pressure that stresses every fixture and appliance on your system. A PRV typically lasts 10 to 15 years; when it begins to go, it rarely announces itself with a single dramatic failure — instead it quietly wreaks havoc on your plumbing until the damage is done.
Lapin Services provides professional pressure reducing valve replacement throughout Orlando and Central Florida. Our licensed plumbing technicians — backed by a combined 200+ years of field experience — test your line pressure, identify the right replacement valve for your system, and install it correctly so you're not dealing with the same issue again next year. With a 4.9-star rating from over 1,000 customers and roots going back to 1958, we're the team Central Florida trusts when plumbing problems need to be solved right the first time.
Problems We Solve
Common Pressure Reducing Valve Replacement Problems We Fix
You do not have to diagnose the problem yourself. These are common issues we help confirm, explain, and repair.
Fluctuating or Inconsistent Water Pressure
A worn PRV diaphragm or spring can no longer hold a steady set point, causing pressure to swing unpredictably — strong one moment, weak the next. This inconsistency strains fixtures and makes everyday tasks like showering or running appliances frustrating and inefficient.
Excessively High Water Pressure
When a PRV fails open, it can allow municipal supply pressure — often 80–150 PSI — to pass directly into your home's plumbing. Sustained high pressure accelerates wear on pipe joints, washing machine hoses, water heater relief valves, and every fixture in the system, increasing the risk of leaks or burst pipes.
Water Hammer and Banging Pipes
Improperly regulated pressure is one of the most common causes of water hammer — the loud thud or bang you hear when a faucet or valve closes quickly. Over time, the hydraulic shock from repeated water hammer can loosen joints, crack fittings, and damage water-using appliances.
Leaking at the PRV or Around the Valve Body
As internal components degrade, water can seep past the valve seat or leak from the valve body itself. Even a slow drip represents wasted water, higher utility bills, and the start of moisture damage to surrounding materials — especially in enclosed utility spaces.
Reduced Hot Water Performance
A failing PRV can interfere with the balanced pressure that tankless water heaters and traditional water heaters depend on. If your hot water seems weaker than your cold, or your water heater is cycling erratically, a degraded PRV may be the underlying cause.
When to Call
Signs Your Plumbing System Needs Professional Attention
If you notice any of these signs, call Lapin. We will find the cause and explain what needs to happen next.
Noticeably Weak Water Pressure Throughout the Home
If every fixture — showers, faucets, outdoor hose bibs — seems to have lost pressure at the same time, the problem is likely upstream of your fixtures. A PRV that has closed down too far restricts flow to the entire system and is one of the first components to check.
Your PRV Is 10 Years Old or More
Most pressure reducing valves have a service life of 10 to 15 years. If yours is approaching or past that range, it's worth having it tested even if you haven't noticed obvious symptoms yet — proactive replacement is far less disruptive than an emergency failure.
Visible Corrosion, Rust, or Mineral Buildup on the Valve
External corrosion or heavy calcium deposits on the valve body are signs the internal components are likely in similar condition. A heavily corroded PRV cannot be relied upon to maintain accurate pressure and should be replaced before it seizes or leaks.
Pressure Gauge Readings Outside the 40–80 PSI Range
A simple water pressure gauge attached to an outdoor hose bib can tell you a great deal. Readings consistently below 40 PSI or above 80 PSI indicate your PRV is no longer doing its job. Anything above 80 PSI puts your plumbing system at risk of accelerated damage.
Appliances or Fixtures Failing Prematurely
Washing machines, dishwashers, ice makers, and water heaters are all rated for operation within a specific pressure range. If you're replacing these appliances more frequently than expected, chronic high pressure from a failing PRV may be shortening their lifespan — and the appliance isn't the real problem.

FAQs
Pressure Reducing Valve Replacement FAQs
What is a pressure reducing valve and why does my home need one?
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.
How do I know if my PRV is failing?
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.
How long does a pressure reducing valve last?
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.
Can I replace a pressure reducing valve myself?
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.
What water pressure should my home be set to?
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.
Do I also need an expansion tank when I replace my PRV?
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.
How long does PRV replacement take?
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.
