Having a good faucet flow rate is essential for the kitchen and bathroom faucets to complete tasks within time. A strong and steady flow of water makes cleaning and washing activities more efficient and convenient. With time, people face low faucet rates.
Several factors can contribute to a reduced flow rate, such as mineral deposits, blockages, faulty components, or plumbing problems. How to increase faucet flow rate to restore it to its optimal performance. By following the solutions outlined in this guide, you will be able to increase the flow rate of the faucet and enjoy a smooth and efficient flow of water.
Ideal Flow Rate For Different Faucets
Kitchen Faucet
The average flow rate for kitchen faucets typically ranges from 1.5 to 2.2 gallons per minute (GPM). However, some high-performance faucets can have a flow rate of up to 2.5 GPM.
Bathroom Faucet
The ideal flow rate for bathroom faucets is generally lower than that of kitchen faucets. Most bathroom faucets aim for a flow rate between 1.2 to 1.5 GPM.
Shower Heads
Showerheads usually have higher flow rates compared to faucets. The standard flow rate for showerheads is around 2.5 GPM. However, water-saving models may have flow rates as low as 1.5 GPM.
You can measure the flow rate of your faucet. Take a bucket and place it under the faucet. Turn on the faucet for one minute and fill the bucket.
After one minute, turn off the faucet and measure the volume of the water. Now divide the water volume by time, it will give you the water flow rate in gallons per minute. If your faucet flow rate is below to normal flow rate, you should increase the flow rate.
How To Increase Faucet Flow Rate?
Method 1 – Remove Mineral Deposits and Debris
Over time, mineral deposits and debris accumulate inside the faucet and cause blockage in the flow of the restrictor. You need to remove the blockage to get the proper flow of the faucet.
- Before cleaning the blockage of mineral deposits and debris, turn off the water supply to the faucet. For this shut off the valve under the sink.
- Carefully remove the faucet aerator. You will find it at the end of the faucet spout. Use a plier or hand to remove the aerator.
- Remove the handle by removing its screw and take out the cartridge and other parts.
- Take a bowl and fill it with vinegar or a lime dissolver solution. Submerge the aerator and other parts of the faucet in the solution for about 30 minutes to an hour. It will help to dissolve mineral deposits and break down any debris.
- After soaking, use a toothbrush to remove any remaining debris.
- When the cleaning is completed, rinse the parts with clean water and reattach them. Before reassembling, make sure that all the faucet parts, including the aerator, are completely clean and dry.
- On the threaded parts of the faucet, apply Teflon tape to make a water-tight seal.
Method 2 – Replace Faulty Parts
If cleaning doesn’t work, replace faulty parts of the faucet. Common faulty parts that affect the flow of water are cartridges, aerators, and screens. Before removing any part, make sure the faucet water supply is off.
At the end of the spout, there is an aerator. Use the plier to remove the aerator. Turn it in a counterclockwise direction to take it out. Don’t damage the threads of the aerator. In some faucets, at the place of the screen, you will find the screen.
Steps To Remove The Cartridge
- You will find the cartridge inside the faucet handle.
- To access the cartridge, remove the handle by unscrewing the set screw. If there is a decorative cap on the screw, remove it with the help of a screwdriver.
- Once the handle is removed, locate the cartridge and unscrew it using pliers or a cartridge removal tool.
- Clean the cartridge area and insert the new cartridge. Align the cartridge properly at the right position.
- Put the handle back in place and secure it with the set screw. If there is a decorative cap, reinstall it.
Do Kitchen Faucets Have Flow Restrictors?
Yes, many kitchen faucets come with a flow restrictor. The flow restrictor is a device that slows down the flow of the water. It reduces the consumption of the water. The flow restrictor is not directly visible. It is installed inside the aerator.
In many U.S. states, there are water efficiency standards and regulations. To comply with these regulations, manufacturers have to use these flow restrictors.
The flow restrictor maintains adequate water pressure for everyday tasks. But if you are experiencing low water flow from the faucet, you can remove the flow restrictor of the faucet. However, it’s important to note that tampering with or removing the flow restrictor may violate local plumbing codes or regulations, and it can also affect the warranty of your faucet.
FAQs
How Does a Faucet Aerator Slow Down The Water Flow?
The aerator of the faucet not only makes the water flow smooth but also slows down the water flow to save water.
The faucet aerator comes with lots of tiny holes. These holes mix the air into the water. When air is mixed into the water, the water flow becomes slow. The water flow is reduced as there is less space for water to come out.
What Is The Average Flow Rate For The Kitchen Faucet?
There are different flow rates for faucets in the market but a common flow rate for many faucets is 1.5 GPM. This flow rate is good for many homeowners. You can go with a 1.8 GPM flow rate also.
