  • The terms "water pressure regulator", "water pressure reducing valve", and "PRV" refer to the same thing. This plumbing component helps regulate and maintain the water pressure coming into your home.

  • Most homes need a PRV. Water coming in from the city's main line may have pressure up to 200 PSI (pounds per square inch). For most homes, 55 to 65 PSI is ideal, and anything above 75 PSI could damage your appliances and compromise both your comfort and your home's entire plumbing system.

  • If your home does not have a PRV, installing one could reduce your water use by 25% to 30%.

PRV replacement cost factors

Several factors can influence the cost of installing a new water pressure regulator:

  • Location: Plumbing contractors may charge additional travel fees if you live outside their service area.

  • Accessibility: If the existing regulator is difficult to access, you may pay higher than average for any additional labor and materials required to replace it.

  • Regulator type: You'll pay more to replace the regulator if your home needs one with a backflow preventer.

  • Material: Brass and bronze regulators cost more than aluminum or plastic models, but PRVs made from higher-quality materials last longer and may be more cost-effective over time.

  • Emergency service: Additional fees may apply if you need to replace the regulator urgently due to a malfunction or water damage. Some professionals charge $100 to $300 more for unscheduled emergency appointments or appointments outside of normal business hours.

  • Home warranty: Some home warranties may cover water pressure regulator replacement.

Labor

The labor cost to install or replace a water pressure regulator ranges from $225 to $450. Plumbers charge $75 to $150 per hour, and most PRV installations take 3 hours (sometimes less) to test the pressure, shut off the water, replace the regulator, and re-test after turning the water supply back on.

Additional factors that affect your potential labor costs include:

  • Adjustment vs. replacement vs. new installation: In some cases, a plumber can adjust a malfunctioning PRV, but most failing units need replacement. Adjusting typically takes less time and costs less than replacement, while replacement usually costs less than a new installation involving additional plumbing work.

  • Pipe modifications: Some installations may involve plumbing system changes to accommodate the new regulator, such as moving the water meter, shutoff valve, or water main inlet location, adding to the total cost.

  • Permit requirements: A plumbing permit costs $50 to $300 and may be required for a PRV installation, depending on your local building codes.

  • Other repairs: Main water line repair costs $400 to $1,500, depending on the issue. If excessive water pressure causes any other damage, additional plumbing repairs will add to your total cost.

Even if you have a well system, you need a water pressure regulator to protect your plumbing fixtures and appliances from excessive water pressure.

Can I install a water pressure regulator myself?

Follow these guidelines when hiring a plumbing contractor near you to install or replace a water pressure regulator:

  • Compare at least three detailed estimates from local plumbing professionals.

  • Choose a high-rated plumbing company that is licensed and insured.

  • Check out their customer reviews on HomeGuide and Google.

  • Be cautious of extremely low estimates, as they may indicate poor quality or lack of experience.

  • Ask for a detailed contract and warranty in writing before the plumber starts working.

  • Don't pay the final bill until the job is complete and the water pressure has been re-tested to confirm the proper PSI.

Asking the right questions can help you select the best plumber for your PRV replacement:

  • Are you licensed and insured?
