Homeowners looking to reduce their water and power bills have the perfect solution in a pressure water regulator. This gadget is pretty useful if you experience irregular water pressure or your water source is a high-pressure municipal line.
This article will explain how a water pressure regulator (or pressure reducing valve, PRV) works and then expound more on all the above ways mentioned to save with the PRV. You will also find helpful tips on saving water and reducing your energy bill.

How a PRV Works
A water pressure-reducing valve and an outdoor hose faucet work in a similar manner.
The PRV is installed near the water main and features an adjustment screw to control water flow through the valve. You only need to tighten the screw to reduce water pressure, thus restricting water flow.
Municipal water usually comes in at high pressure, at times reaching up to 150 psi (pounds per square inch). However, most residential plumbing fixtures perform best at about 50 psi.
When water passes through the PRV at high pressure, its inner mechanism reacts by narrowing the flow area, thereby reducing the pressure to between 50 and 80 psi. The PRV also permits more water to flow if the incoming water pressure falls.
A PRV thus helps lower the pressure of water getting into your home by moderating the flow. In this regard, it protects your plumbing and fixtures from unnecessary wear and tear.
However, messed-up pipes and fixtures are not the only things to contend with when you have high water pressure and water surges. The intense pressure can also cause you to spend lots of money on repairs. You may also face additional problems, such as:
- Dripping faucets
- Leaking sprinkler valves
- High water bills
- Broken or burst pipes
- Running toilets
- Banging pipe sounds (water hammer) – a sure sign that your water pressure is excessive
- Damaged appliances, including washing machines, water heaters, refrigerators, and dishwashers
This short video explains what a water pressure regulator is and what it does.
Ways To Save With a Pressure Relief Value
Here are several effective ways to save with a home water pressure regulator:
- Reduce your water consumption.
- Stabilize your water pressure.
- Protect your household appliances.
- Save money on energy and water bills.
- Protect your water heater.
- Minimize water leaks.
How a PRV Can Save and Regulate Water Pressure
Below are several ways a PRV can help you save and regulate your water pressure. It can:
1. Reduce Your Water Consumption
To reduce water wastage, you should avoid your water pressure going beyond 50 psi. A PRV comes in handy if the city water entering your house comes in at high pressure (above 80 psi).
You could also experience high water pressure if your water heater has a faulty expansion tank or you live close to a fire hydrant.
The water pressure regulator helps lower this pressure and regulates water flow, helping you conserve water. Besides, reducing your water pressure by 10- 20 psi could result in thousands of water gallons per year in potential savings.
To put this in perspective, reducing water pressure from 100 to 50 lbs (45.35-22.68 kgs) results in savings of up to 33%. Likewise, the water flowing at this lower pressure will also reduce by a third. This drop results because water at 100 lbs experiences a higher push than water at 50 lbs.
According to the Environmental Protection Agency (EPA), a typical American family consumes 300+ gallons of water per day. Most of this water usage occurs indoors. And that translates to thousands of dollars annually in water payments.
Below is a chart showing the results of a survey conducted on average American household water usage by the Water Research Foundation. It breaks down the average daily consumption per household.
2. Stabilize Water Pressure
By controlling the amount of pressure in your incoming water, a PRV helps to stabilize the water pressure. What’s the effect?
Stabilization helps you have a relaxing shower instead of enduring a jet stream. You can also wash dishes in comfort, without water splashing all over you.
You can get a plumbing contractor to perform a test (using a pressure gauge) to confirm whether your water pressure is higher than necessary.
3. Protect Your Household Appliances
Household appliances suffer damage when forced to handle high water pressure since it puts a heavy strain on them. With a PRV, you are assured of steady, regulated water flow that allows your appliances to perform optimally, thus prolonging their life.
4. Save Money on Energy and Water Bills
More water runs out every time you shower, flush a toilet, or turn on a faucet with high water pressure. Eventually, you end up paying more for this excess consumption.
Also, according to the EPA, American households heat approximately 30% of their water. And heating uses energy.
Installing a PRV helps you save money by reducing your energy bills, water bills, and even wastewater bills considerably. By cutting water consumption by up to a third, the PRV minimizes the energy needed to heat water.
In other words, saving water translates to increased energy conservation. You will also experience fewer appliance repairs or replacements.
Consider swapping your faucets, showerheads, and toilets for water-efficient models designed to deliver excellent water pressure with minimal water use to increase your savings even further.
Doing so could result in a 20% reduction in water usage, allowing an average family to save around $130 in water bills and 13,000 gallons of water every year.
Here are additional tips on how to conserve your water:
- Attend to household leaks as soon as they occur.
- Turn off the water between washing dishes while brushing your teeth or soaping yourself ( in the shower).
- Run your dishwasher when it’s full—eliminating a load of dishes each week can save your family almost 320 gallons of water per year.
5. Protect Your Water Heater
Consistent high water pressure can mess up your water heating system. While water heaters usually contain a thermal expansion tank to handle water expansion upon heating, the expansion space might run out if your water pressure is always high.
This buildup can seriously damage your water heater. A PRV can prevent such damage.
6. Minimize Water Leaks
Excessively high pressure poses a significant danger to your pipes. Heavy water flow can lead to leaks or hairline cracks in the pipes, resulting in a massive blowout.
Even worse, water leaks often result in extensive damage to floors, walls, drywall, and cabinets that entail huge reconstruction and restoration. Mold infestation is also highly likely in moisture-laden environments.
To prevent a severe plumbing disaster or structural damage, you might want to consider regulating your water pressure sooner rather than later.
Fortunately, you can do the installation on your own by following basic guidelines. Alternatively, you have the otion to call in a plumber.
