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 by type
The cost of replacing a water pressure regulator can vary depending on the specific type of regulator you need. The most common type of regulator for residential homes is a direct-acting valve costing $75 to $200, plus installation. Other regulators for sprinklers or larger buildings cost more.
| PRV type | Average price* | Details |
|---|---|---|
| Direct-acting valve | $75 – $200 |
|
| PRV with backflow protection | $150 – $600+ |
|
| Pilot-operated valve | $500 – $5,000+ |

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 are DIY-savvy and have plumbing experience, the only PRV installation you should consider tackling yourself is replacing an existing PRV with a new one of the same model, size, and manufacturer. Hire a licensed plumber if the job involves more complex plumbing work.
