Water Pressure Reducing Valves - Expert Plumbing Installation in NOVA

Low water pressure can be a significant aggravation in your Northern Virginia home. If you get only a weak stream instead of a strong stream when you turn on your faucets, that can lead to problems with cleaning, bathing, and overall home sanitation.

Check with your neighbors, if low water pressure is only affecting your house, check to see if a water pressure reducing valve has been installed. DB’s Plumbing & Drain® can do the necessary adjustments to increase water pressure throughout your home.

Another thing that can cause low water pressure is a leak in the main water lines or somewhere else. Check inside your home for leaks in areas such as basements, garages, or at points where water supply pipes enter your home. See if there are wet spots in your lawn that could indicate an underground water leak. If so, call us right away for our leak detection service.


Why Do I Need Pressure Reducing Valves?

Water pressure regulators are devices that protect plumbing systems from excessive water pressure damage by reducing incoming high water main pressure. If you didn't have a pressure-reducing valve installed between the municipal water system and your house, the water pressure would break all your water lines. The pressure in a municipal system can be as much as 200 psi to service fire hydrants and high-rise buildings, but the pressure in a typical residence is usually around 50 psi. The step-down regulator near your water meter or just outside the house adjusts to the level needed in a typical residence in Prince William County.

Save money With Pressure Reducing Valves

As most of us already know, reducing water consumption can save money and have an impact on the environment. One easy way to start saving money and reducing water consumption is by using a pressure reducing valve.

Pressure reducing valves help home owners save money, water and energy by reducing the amount of water being used and ultimately, wasted. According to research, a faucet left running for ten minutes with a water pressure of 50 psi uses 30 gallons of water; at 150 psi, it uses 56 gallons of water. A pressure reducing valve decreases that incoming pressure from the water supply and sets a low, regulated water pressure for the entire home. The pressure reducing valve can help decrease water usage by one third. That makes for real savings.

If you experience a sudden reduction in water pressure, it's a good idea to check with the water company. There may be a temporary problem with the municipal system. Water pressure may also fluctuate during peak demand. If so, an adjustment to your will be too high once the municipal problem is corrected. That said, most low water pressure problems originate from inside the home. Here are some common culprits:


Clogged Aerators - If you only have low pressure at one faucet, it may be a clogged aerator. Check the aerator screen for rust, debris, and other particles restricting flow. This most commonly occurs when water service is shut-off. Without pressure in the indoor plumbing system, mineral particles adhering to your pipes flake off and become trapped in the aerator filter.

Water Softener Systems - Water softeners can cause a sudden change or decrease in water pressure. To check it, switch the water softener to bypass mode and see if pressure improves. You may also want to have the water softener serviced by a service technician, if you believe it’s the cause of your low pressure.

Shut off Valve - The shut-off valve shuts off water to the home. It’s normally located where the water service pipe comes into the home. If this valve is partially closed, it will affect water pressure throughout the entire home. Check that the valve is completely open.

Low Hot Water Pressure - Problems at the water heater, such as a partially closed shut-off valve, could reduce the pressure of hot water flowing to your kitchen and bathroom.


Low Flow in Older Homes - A common problem in older homes (generally 50+ years and older) is a reduction of flow rate. Over time, mineral deposits and corrosion sediment accumulate on the interior of galvanized pipes. This decreases the diameter of the interior pipe, creating a more turbulent and restricted path for the water. This internal build-up of minerals and corrosion does not pose a safety concern, but it does cause weaker flow. Indoor plumbing and the service line are owned by and the responsibility of the property owner.
