Why You Should Install A Pressure Reducing Valve

If you're dealing with high water pressure in your home, you might be facing hidden dangers that could cost you thousands in repairs. While strong water pressure might seem like a good thing, more power in the shower, faster fill times for sinks and tubs, uncontrolled pressure can wreak havoc on your plumbing system.

That’s where a Pressure Reducing Valve (PRV) comes in.

Whether you’re a homeowner asking, “Do I need a pressure reducing valve?” or simply trying to understand “What does a pressure reducing valve do?”, this post will walk you through the essentials. As professional plumbers in Tulsa, we at Spot On Plumbing want to help you protect your home and your wallet by understanding the role a PRV can play in your plumbing system.

PRV

What Is a Pressure Reducing Valve (PRV)?

A pressure reducing valve is a plumbing device installed on your main water line, typically just after the water meter. Its job is to regulate incoming water pressure from the municipal supply and reduce it to a safe, manageable level for your home’s plumbing system.

Most residential plumbing systems are designed to handle water pressure between 40 and 60 psi. However, city water supplies can often exceed 100 psi, especially in areas of Tulsa with strong municipal systems or elevation changes. Without a PRV, this excessive pressure can cause long-term damage to pipes, fixtures, appliances, and more.

What Does a Pressure Reducing Valve Do?

If you’ve been wondering, “What does a pressure reducing valve do?”, here’s a breakdown of the key benefits:

1. Protects Your Plumbing System

High water pressure can lead to burst pipes, leaking fixtures, and premature wear on your plumbing system. A pressure reducing valve acts as your home's first line of defense, regulating the water to a safe level.

2. Extends the Life of Appliances

Appliances like water heaters, washing machines, dishwashers, and even ice makers can be damaged by excessive water pressure. Installing a PRV helps these appliances function efficiently and last longer.

3. Prevents Water Waste

Excessive water pressure can lead to water waste. A PRV helps reduce your water usage, which can lower your monthly utility bills and help conserve a precious resource.

4. Reduces Noise

Ever heard banging or clanging in your pipes? That’s called water hammer, and it’s often a result of high pressure. A PRV helps reduce or eliminate this annoying and potentially damaging issue.

How Does a Pressure Reducing Valve Work?

You might be asking, “How does a pressure reducing valve work?”

Great question.

A PRV contains an internal spring and diaphragm mechanism. As high-pressure water enters the valve, the spring compresses and restricts the flow, reducing the pressure to a preset level (usually between 50–60 psi). The valve automatically adjusts to maintain consistent pressure, even if the municipal supply fluctuates.

Many PRVs are adjustable, so your Tulsa plumber can fine-tune the pressure based on your home’s specific needs.

Do I Need a Pressure Reducing Valve?

Here’s the million-dollar question: “Do I need a pressure reducing valve?”

Here are some signs and scenarios where a PRV may be necessary:

You Have High Water Pressure

If your water pressure exceeds 80 psi (which you can measure using a pressure gauge on an outside hose bib), a PRV is not only recommended, it’s often required by plumbing code.

Your Pipes or Fixtures Leak Frequently

High pressure puts stress on plumbing joints and seals, causing chronic leaks or even pipe bursts over time.

Your Appliances Keep Breaking Down

If you’ve had to replace your water heater, dishwasher, or washing machine earlier than expected, high water pressure could be to blame.

You Hear Strange Noises in Your Plumbing

Water hammer, pipe knocking, and other noises can indicate that the pressure in your system is too high.

If any of these signs sound familiar, it’s time to talk to a professional Tulsa plumber like the team at Spot On Plumbing.

Pressure Reducing Valve (PRV) FAQsCan I install a PRV myself?

While it’s possible for experienced DIYers, PRV installation usually requires cutting into your main water line. For safety and code compliance, we highly recommend calling a licensed Tulsa plumber.

How long does a PRV last?

Most PRVs last 10–15 years with normal use. If you notice pressure issues returning, it might be time for a replacement.

Is it required by code?

In many municipalities, a PRV is required by plumbing code if water pressure exceeds 80 psi. We can help you verify whether this applies in your neighborhood.

Can a PRV improve water conservation?

Yes! Lowering the pressure reduces water usage across all your fixtures and appliances.
