Owning a home comes with a lot of excitement and some occasional stress. When items in the home start to break down or malfunction it can create a burden on the homeowner. Loss of water pressure is one of those burdens. Homeowners need water for a variety of tasks in the home. So, if the water pressure is not good in the kitchen sink, you can’t clean your dishes or wash your hands. Need to know how to increase water pressure in a kitchen sink? Check with the water utility company to ensure they aren’t experiencing any issues.

What Are Some Causes Of The Low Pressure?

Unfortunately, there are a variety of items that can cause your kitchen sink to have low water pressure.Too solve the problem, you will need to troubleshoot every possibility or hire a master plumber to assist. Let’s take a look below at the list of items that should be examined for a solution.

  • Check the aerator – The aerator screen may be clogged. Remove the aerator and soak it in vinegar and rinsing it out is a great start. If the vinegar and baking soda do not clean the screen, then you should purchase a new aerator screen at your local hardware store.
  • Check the cartridge – At the base of your faucet, there is a cartridge tucked away inside your faucet hardware. Turn off the water and remove the faucet. First, replace the rubber o-ring and any seals, and then clean the cartridge in the same manner that you cleaned the aerator.
  • Check the regulator – Located at the service line or main water meter box. You will want to check to ensure that it hasn’t gone bad. They are installed to prevent a rush of water from coming into the home and causing a water hammer. If the regulator is bad, it will reduce water velocity, which will reduce water pressure on your faucets.
  • Damaged faucet – If you find that the aerator and cartridge are working properly, it is possible that other parts of the faucet are damaged. This might be a good time to replace the kitchen faucet.
  • Leaking pipe – unfortunately, leaking pipes are at some point expected. Low water pressure can be a result of leaking pipes. A master plumber will need to come out and inspect the pipes and check for leaks.
  • The water line is blocked – If you have a blockage in the main water line, whether it is toward the main connection or somewhere in your walls, a blocked line can prevent the proper flow of water. Slow water flows are also good indicators of a blockage in the line.
  • Flush the water heater – Use your garden hose and connect it to the hose bib at the bottom of your water heater. Open up the spigot and let the water flow out of the water heater. Once the system is drained you can determine if sediment and other debris have built up in the water heater.
  • Sediment buildup – Low water pressure when using hot water is almost always a cause of the water heater being clogged. Drain or flush the water heater once every 6 months. This will keep your energy bills low and prevent the likelihood of a low water pressure situation.

What Is Another Way To Increase Water Pressure In A Kitchen Sink

If all else fails, you can look to install a pressure booster. In some cases, the distance of your home from the main water line and gravity can really slow the travel of water through your pipes. Installing a water pressure booster will increase the water flow from the local water source to your home.

How Much Does It Cost?

Getting your water pressure fixed in the kitchen sink can be a rather annoying issue. There are so many possibilities for this to occur that you are guaranteed to call a master plumber. The likely fee to unclog any plumbing lines ranges from $150 to $200. The bad thing is, the lines might not be the only item causing low water pressure. If the water pressure regulator needs to be replaced the range for that is from $250 to $400. Fixing low water pressure can add up to be a costly repair.

Other Recommended Maintenance

Now that you have an idea of how to fix your low-water pressure issues, this would be a great time to check the caulk around the kitchen sink to see if the caulk wears off of the kitchen sink and it needs caulking. Choose a water-proof silicone-based sealant, then remove the old caulk, let it dry, and then add new caulk. It is important to do this so water and pests don’t get under your sink.

Next, this would be a great time to get your water lines checked. In some cases, the low-water pressure can result from sediment in the water lines. Check your aerator screens and the water heater to determine if flushing the water heater solves the problem.

Lastly, read up on how temperature controls work with your water heater and your plumbing. Getting an understanding of why your shower water is cold, but faucet water is hot can lead you to a quick assessment of what needs to be replaced.

Low water pressure in your sinks can be a nightmare. Call on a master plumber to help fix the issue.
