How to Adjust the Water Pressure of Your Bathroom Faucet

High-flow faucets are great when trying to fill up your tub or sink quickly.

While high water pressure can be convenient, it can also cause disasters down the road, from damaged pipes, broken fixtures or appliances as well as higher utility bills.

If you’re not ready to replace your bathroom faucets but you’d like to avoid falling into long-term inconveniences, we have a few possible solutions.

Understanding Water Flow Rates

In the U.S., the maximum flow rate for bathroom faucets is 2.2 gallons per minute (GPM) at 60 pounds per square inch (PSI). The federal government has set this flow rate and required bathroom and kitchen faucet manufacturers to comply with the standards.

Faucets with a WaterSense label meet the U.S. Environmental Protection Agency (EPA)’s criterion for water efficiency and performance. WaterSense compliant faucets use at least 20 percent less water, save energy, and perform better than regular models. Many states have implemented even more strict water flow restrictions.

Water Pressure & Water Flow

While water pressure and water flow are often used interchangeably, these two mean different things. The former is the force that pushes the water through pipes, while the latter is the amount of water passing through pipes at a given time.

High water pressure creates high water flow. When water pressure is sufficient, water flows through the pipe faster. Conversely, the lower the water pressure, the harder it will be to disperse water out of the pipes.

Both low and high water pressure present problems.

3 Ways to Regulate Water Flow of Your Bathroom Faucet

If your home has high water pressure and you wish to reduce your home’s monthly water usage, these three tips will do the trick:

1. Install water pressure regulator

When the water pressure is too high, it forces the water out of the pipes faster. While this may seem ideal, high-water pressure may do more harm than good.

Extreme water pressure doesn’t only cause you to waste water every time you turn on your bathroom tap, but it also leads to plumbing problems.  Most faucets are tested to 60 PSI.

To avoid these from happening, have a plumber install a water pressure regulator to reduce the chances of leaks and pipe bursts, as well as conserve water and cut utility costs. 

2. Replace the water aerator

According to the U.S. Environmental Protection Agency (EPA), aerators are an effective water-saving technique that can be employed in homes.

A water aerator is a small attachment fitted at the end of faucets. Aerators come with a screen, which helps span the opening of the tap and break the water flow into multiple smaller streams.

By installing a top-quality aerator, the amount of water exiting your faucet is regulated, resulting in utility bill savings. Most high-quality faucets today have built-in aerators. Check your bathroom faucet to see if the aerator is working, and install a new one if it needs replacement.

You may also consider buying a new bathroom faucet with a water-saving aerator like Lulani’s Yasawa single-hole bathroom faucet for peace of mind.

3. Adjust the valve underneath the sink

The shut-off valves underneath your sink play an integral role in controlling how much water goes through your pipes.

If you wish to reduce the water pressure to a particular faucet, turn the valves clockwise by a quarter rotation. Make sure to turn the cold and hot water valves equally to create more consistent water pressure.

Summing It Up

Reducing your home’s water usage could start with your faucets. You can do many things to save water, from replacing your old water aerator to installing a water pressure regulator and adjusting the shut-off valves.
