What Is a Pressure Reducing Valve

Definition of a Pressure Reducing Valve

A pressure reducing valve, or PRV, is a device designed to regulate and stabilize the water supply pressure in a plumbing system. It achieves this by controlling how much water is allowed to flow through it, effectively reducing high incoming pressure to a steady, pre-determined level. This precise pressure control is essential to ensure that water pressure remains consistent, regardless of changes in usage or fluctuations in upstream pressure.

PRVs are vital to protecting plumbing infrastructure and serve to guard against over pressure that can cause premature stress on pipes, fixtures, and appliances. The PRV is a hydraulic, pressure-reactive diaphragm valve that takes the higher pressure from upstream and reduces it to a safer, more controllable downstream level while allowing water to flow continuously and evenly. This control valve system is crucial for maintaining the integrity of the plumbing system.

By preventing excess water pressure, a PRV contributes to the overall efficiency and longevity of plumbing systems. For instance, it eliminates problems such as banging pipes or dripping faucets, which are often a result of pulsating pressure caused by improper regulation.

How It Works in a Plumbing System

PRV mechanism is very simple but works very well. It employs a pilot valve, sometimes called the “brain,” to modulate water traveling through the system. As demand increases and water flows out, the PRV compensates by opening more to lower pressure and vice versa.

Our V port throttling plug allows for exacting control, including at very low flow rates. It achieves this without overloading the system. Usually, PRVs are placed on the incoming water line, right after the water meter. This intentional positioning allows the entire plumbing infrastructure to receive the advantages of controlled pressure.

Preventive maintenance is important to keep debris out of the valve’s internals to allow it to run freely and for many years with little maintenance. The long-term financial benefits of a properly installed PRV could save homeowners thousands in necessary repairs, with short-term installation costs at $50 to $500.

Importance of a Pressure Reducing Valve

Protecting plumbing fixtures and appliances

Even stable water pressure is important in preventing premature damage and tear on faucets, showerheads, and other fixtures. When water pressure gets dangerously high, these components are subjected to too much force. This additional pressure puts a strain on them, causing them to fail at an accelerated rate.

A faucet designed to withstand full pressure may start to leak or drip before its time. This is especially true when it’s subjected to unrelenting, high pressure. Household appliances such as dishwashers and washing machines are similarly affected.

Too much pressure can over-stress internal components, leading to premature failure and costly repairs. Adding a pressure reducing valve (PRV) to your irrigation system keeps pressure levels even. This reliable protection ensures your investments stay on track for years to come.

Preventing pipe damage from high pressure

If high water pressure is the culprit, it can silently wreak havoc on the integrity of your pipes over time. This additional stress makes them more susceptible to leaks. Even worse, it might result in unexpected breaks that create costly water damage.

For example, if you have copper or PVC pipes, they may fracture under sustained pressure above 80 psi. A PRV is a protective measure. It brings excessive pressure down to a safe, workable level and avoids these expensive problems.

It’s an inexpensive but smart investment to safeguard the backbone of your residential plumbing system.

Enhancing water usage efficiency

The bottom line is that a PRV doesn’t just protect—it saves. By regulating water pressure, it helps get water where it needs to go without excessive pressure wasting water.

For instance, less pressure means less water wasted while people go about their daily routines—washing hands, rinsing dishes, washing a car, etc. That’s less water that goes to waste, and ultimately utility bills are kept lower and more stable.

More importantly, this controlled flow benefits your wallet. Beyond its budgetary benefits, it makes the state a better steward of the environment by lowering overall consumption.

Benefits of Using a Pressure Reducing Valve

Extending the lifespan of plumbing systems

Here’s why a pressure reducing valve (PRV) is one of the most important devices you need to protect your plumbing system. By reducing water pressure to an ideal level, it avoids putting unnecessary stress on pipes, joints, and fixtures. This prevents premature wear and tear, allowing fixtures like faucets, showerheads, and appliances to last longer.

Like hypertension in the human body, excessive water pressure can put a serious strain on the system. This repeated stress is a recipe for potential failure down the line. The lower the pressure, the less chance of leaks, bursts, or water hammer which requires costly and frequent maintenance.

As another example, a properly maintained PRV can reduce repair requirements by up to 50%, reducing their repair time and cost. Consistently checking your PRV will provide this continuous safeguard, prolonging the overall lifespan of your plumbing system.

Reducing water waste and utility costs

One of the primary ways a water pressure regulator (PRV) saves water is by effectively lowering water pressure, which subsequently decreases water usage at the source. For instance, reducing the pressure from 100 psi to 50 psi can lead to substantial water savings, potentially saving you nearly one-third on your water bills. This reduction is crucial as it contributes to the overall efficiency of your plumbing system.

In reality, homeowners could save more than $200 annually when considering water heating and sewer costs. With lower water supply pressure, it takes less water to heat, which translates to lower energy expenses. This aspect is especially significant since approximately one-third of residential water is typically heated.

In reality, real-world examples go as far as demonstrating the use of pressure reducing valves to save millions of gallons, providing enormous financial and environmental returns.

Improving overall system safety

Safety is a key benefit of using a PRV. This helps reduce the risk of pressure-related problems such as water hammer, which can severely damage pipes and appliances. By ensuring pressure levels remain within safe limits, it helps prevent leaks and pipe bursts, sidestepping expensive emergencies.

From a safety perspective, this added layer brings peace of mind. A high-quality, dependable PRV can keep abrupt, costly plumbing disasters at bay. This helps your home’s system operate effectively, helping you avoid surprise shutdowns.

Consequences of Not Having a Pressure Reducing Valve

Increased risk of pipe bursts and leaks

High water pressure in your plumbing system is like high blood pressure in your body. Ignore one or the other and you may be headed for disaster. Too much pressure always exerts a lot of pressure on your pipes making it more prone for a sudden failure or leak to occur.

Even the tiniest crack in a pipe can lead to significant water damage. It can devastate your floors, walls, and furniture in a matter of days. Just one dripping faucet can waste almost two gallons of water a day. A running toilet wastes about four gallons each hour!

Without a PRV, issues can compound in an instant. Failing to do so can result in expensive damage and a whole lot of extra hassle.

Higher water bills due to inefficiency

Uncontrolled water pressure can lead to increased water usage, increasing your utility bill. When water is flowing as forcefully as possible, appliances and fixtures require more water than necessary, driving your water bills much higher.

Unsuspecting homeowners will start seeing their costs go up without understanding that high pressure is the culprit. Adding a PRV can prevent a substantial amount of water waste—up to one-third.

Not only does this conserve water, it reduces the amount flowing to the sewer system for treatment. In the long run, that makes this simple step a boon both for the environment and municipal budgets.

Damage to household appliances and fixtures

It’s not only hard on your pipes, high water pressure can damage your appliances and fixtures as well. Dishwashers, washing machines, and water heaters endure unnecessary wear and tear caused by constant pressure fluctuations, ultimately shortening their lifespan.

Fixtures such as faucets and showerheads can drip, leak and/or stop functioning properly. Recommended water pressure by code, water pressure inside your home should remain between 40-80 psi.

A PRV provides a constant pressure, safeguarding these investments and avoiding costly replacements or repairs.

Signs You May Need a Pressure Reducing Valve

A pressure reducing valve (PRV) is crucial for maintaining appropriate water pressure in your plumbing system. Homeowners should watch for signs that indicate the need for a valve works.

Loud pipes or banging noises when you run your water. This is usually due to excessive pressure or a defective PRV. Repetitive knocking or humming sounds coming from the walls are dead giveaways.
Frequent leaks or drips on your faucets and fixtures. These are all signs that high water pressure is putting a strain on your plumbing.
Excessively high water pressure on your gauges. If consistently above 80 psi that’s a red flag that your PRV is likely not doing its job.

Experiencing Frequent Plumbing Issues

Recurring plumbing problems, like leaks, burst pipes, or loss of pressure when multiple fixtures run, may point to high water pressure. Fixing these problems sooner rather than later can save a lot more expensive repair work down the road.

A licensed plumber can help determine whether your PRV is in good working order—or if it’s time for a repair or replacement.

Noticing Unusually High Water Pressure

You can test your water pressure with an inexpensive pressure gauge, which can be screwed on to an outdoor spigot. Residential systems tend to work most efficiently between 40 and 60 psi.

If it’s higher, your PRV may not be functioning properly. Routine monitoring and testing help keep your system well within this less damaging range.

Observing Spikes in Water Bills

Excess pressure overworks and wastes water and can result in surprise utility bills. Monitoring bills monthly as well as usage trends over time can help identify anomalies.

When we investigate these pressure spikes, we almost always find some underlying pressure problem that a PRV can fix.

How to Maintain a Pressure Reducing Valve

Good preventative maintenance of a pressure reducing valve (PRV) will go a long way in preserving your plumbing system and ensuring appropriate water pressure, ultimately saving homeowners money on maintenance costs.

Conduct regular inspections for leaks and performance issues.
Clean the valve to remove debris and mineral buildup.
Schedule replacements based on age and condition.

Inspecting the valve regularly for wear

Routine inspection will not only make sure your PRV is working as it should but avoid damaging and potentially expensive issues. Watch for indications such as leaks, corrosion, or weird noises.

For instance, water pooling around the valve or the appearance of rusting should be signs of aging. For future maintenance, documenting these findings will be useful in tracking the valve’s condition over time.

Have a professional plumber check your PRV annually to prevent big problems down the road.

Cleaning and removing debris buildup

As time passes, debris and minerals can build up inside the valve, interfering with its ability to work. Removing blockage from the valve allows water to flow freely, keeping redirection in the valve from creating fluctuating pressure.

Carefully disconnect the PRV, rinse it thoroughly with water, and clean away any mineral buildup. Annual cleaning during regular maintenance will keep low water pressure at bay and help the valve perform its best.

Regularly cleaning valves saves water, too—up to one-third of water usage in some cases.

Replacing the valve when necessary

Typical PRV lifespans range from 7 to 12 years, but they can fail prematurely if damaged. Signs such as ongoing leaks or pressure problems indicate it’s time to replace it.

Replacing in a timely manner prevents more extensive plumbing issues and saves energy by decreasing the use of hot water. Consider having your pressure reducing valve professionally installed for the best safety and performance.
