If your home’s water pressure feels unusually strong — or you’re dealing with leaking faucets, running toilets, or banging pipes — you may have an issue with your pressure reducing valve (PRV).

A properly functioning PRV protects your plumbing system, prevents costly damage, and ensures safe, comfortable water pressure throughout your home.

Let’s break down what a PRV does, how to know when it’s failing, and when it’s time to repair or replace it.

What Is a Pressure Reducing Valve (PRV)?

A pressure reducing valve is a plumbing device installed on your main water line that regulates the amount of water pressure entering your home.

Most municipal water supplies deliver water at very high pressure — often over 100 PSI — which is too strong for residential plumbing systems.

A PRV reduces that pressure to a safe level, typically around 50–70 PSI, helping protect:

  • Pipes and fittings
  • Water heaters
  • Faucets and shower valves
  • Toilets and appliances
  • Irrigation systems

Without a working PRV, your plumbing system may wear out faster and become more prone to leaks or bursts.

Signs You May Need Pressure Reducing Valve Repair or Replacement

PRVs don’t last forever. Over time, internal springs and diaphragms wear down.

Here are the most common warning signs homeowners in San Diego county north and surrounding areas should watch for:

1. High Water Pressure

If your water pressure feels suddenly stronger than normal, your PRV may be failing.

A plumber can test your PSI and confirm whether it’s exceeding safe limits.

2. Banging or Shaking Pipes (Water Hammer)

Do you hear loud banging when shutting off faucets or running appliances?

Excessive pressure can cause “water hammer,” which stresses pipes and joints.

3. Frequent Leaks or Fixture Failures

High pressure often leads to:

Dripping faucets

Toilet fill valve failures

Appliance hose leaks

Premature pipe damage

4. Pressure That Fluctuates

If your shower pressure changes randomly or you get bursts of high pressure, your PRV may no longer regulate properly.

5. A PRV Older Than 10–15 Years

Most pressure reducing valves last about 10–15 years depending on water quality and usage.

If yours is aging, replacement is often the safest choice.

Pressure Reducing Valve Installation in San Marcos, CA

If your home doesn’t already have a PRV — or you’ve recently installed a new water line — PRV installation is one of the smartest plumbing upgrades you can make.

At Plotke Plumbing & Heating Inc, our PRV installation process includes:

✔Testing incoming water pressure

✔Selecting the correct valve type and size

✔Professional installation to code

✔Adjusting pressure to the ideal PSI

✔Ensuring long-term protection for your plumbing system

✔Proper installation is critical — an incorrectly installed valve can cause pressure imbalance, leaks, or reduced water flow.

Pressure Reducing Valve Repair vs Replacement

Homeowners often ask: Can a PRV be repaired, or does it need to be replaced?

PRV Repair May Be Possible If:

  • The valve is fairly new
  • Pressure adjustment has slipped
  • Internal components are still in good shape
  • The issue is minor or intermittent

PRV Replacement Is Recommended If:

  • The valve is leaking
  • Pressure remains high even after adjustment
  • The PRV is corroded or failing internally
  • It’s over 10 years old
  • You want a long-term solution

Our plumbers will always give honest recommendations based on safety, cost, and longevity.

Why High Water Pressure Is a Serious Plumbing Problem

Many homeowners don’t realize that excessive water pressure is one of the leading causes of plumbing damage.

Unchecked high PSI can lead to:

✔Pipe bursts

✔Hidden slab leaks

✔Water heater damage

✔Costly fixture replacements

✔Increased water bills

Installing or replacing a PRV is preventative plumbing that saves thousands over time.

We at Plotke Plumbing & Heating have noticed an increase in calls from our customers experiencing problems with their water heater and hot water fixtures in the home. Often, these issues are related to a water heater that needs to be serviced, checked, and cleaned with a flush. Reasons to Flush and Service a Water Heater: -Getting the full life expectancy out of the the tankless...like a car or even the human body the better you take care of it and service it, the longer it will last. -Hard water in San Diego is very tough on the inner components of water heaters. -Sediment build up only gets worse if they are not flushed regularly. The build up will then travel through the water heater to all fixtures in the home, causing wear and tear on the inner plumbing from the seals to the faucet aerators and shower heads. These fixtures clog up and corrode to the point that cleaning is surpassed and they need to be replaced. -Some manufacturers won't honor a warranty if the water heater was not properly maintained during it's useful life.

We've seen a large increase in our customers calling us for water leaks lately. Often they don't know the source of the leak, but they get a very large water bill, sometimes months later, and immediately know something is wrong. Or they hear a sound of water running. Or sometimes even see water creeping in through concrete or through the wall or light fixture. While this sounds awful, it's actually quite common. Don't panic! Call us at Plotke Plumbing & Heating and one of our plumbers who specializes in water leaks will be out right away to both find out what is causing the leak, but will also fix it for you right the first time! Common causes of plumbing leaks in our Northern San Diego community can include: High Water Pressure Excessively high pressure stresses pipes and joints, often leading to cracks or drips—especially in shower heads, faucets, and older plumbing systems. Aging, Corroded, or Worn-Out Pipes Over time, metal pipes (especially galvanized steel or copper) deteriorate due to mineral-laden (hard) water and natural aging, leading to leaks. Poorly Installed or Degraded Joints & Seals Pipe joints are common weak points; poor installation, aging sealants, or thermal shifts can cause leaks around connectors, faucets, and appliances. Broken or Drying Appliance Seals & Loose Connectors Rubber seals on appliances like dishwashers, washing machines, or heaters can dry out and crack, while hoses may loosen—both leading to unnoticed drips. Clogged Drains Causing Pressure Build-Up Hair, grease, soap, or flushing unsuitable items can block pipes, creating back-pressure that stresses pipes and often results in leaks. Tree Root Intrusion & Underground Damage Nearby tree roots can infiltrate underground piping—especially sewer lines—causing blockages or fractures that eventually lead to leaks. Chemical Damage from Harsh Drain Cleaners Using corrosive chemical cleaners frequently degrades pipe interiors and seals, making leaks more likely. DIY or Poor Construction Practices Over-tightening fixtures, installing off-brand parts, or using improper techniques can compromise seal integrity and pipe structure over time. Stray-Current Corrosion (Copper Pinhole Leaks) In systems where electrical grounding is disrupted (e.g., after installing plastic components), copper pipes can pit and develop pinholes within months. Whether it's one of these common culprits or something else, Plotke Plumbing & Heating has you covered as qualified plumbers who specialize in leaks repairs. If you're searching for a plumbing in the Encinitas, San Marcos, Carlsbad, and surrounding areas for a plumbing leak repair, give us a call and we are very happy to help! And for a limited time, we're offering a $75 off any water leak repair since we've had so many frantic customers calling us lately for this very concern. Offer valid through 9/30/25.
