How To Increase Water Pressure in a Kitchen Sink? With 6 Solutions

Finally had the energy to wash the dishes, but not much water came out after turning on the faucet? The sudden drop of water pressure in kitchen equipment is the most troublesome problem for homeowners. Imagine you have a sink full of dirty dishes, you turn on the tap, and your water only drips out! Several different issues led to this situation. Today, we will tell you all about how to increase water pressure in a kitchen sink.

The first thing you need to do is check whether the water pressure of the other faucets in the house is high or low. If the water pressure of all faucets is shallow, there may be a problem with the plumbing in the house. However, it’s just that the water pressure of the kitchen faucet is low, then this article gives some ideas to increase water pressure in the kitchen sink. You can use these methods to increase water pressure in a kitchen sink.

Solutions to Increase Water Pressure in a Kitchen Sink (With Causes)

1. Leaking Pipes

leaking pipes - increase water pressure in the kitchen sink

If your basement had flooded, you already know that your pipeline is leaking. Leaks can mislead your water supply, so you will not get the entire flow even if everything else is working. Leaking pipes can also cause water pressure to drop. However, the challenge with leaks is that they are not always visible. Look around to see if there are any wet spots. Find out which pipe is leaking and try to fix it quickly. Again, if you notice a change in water pressure due to a pipe leak, you may have to deal with more than one leak.

Solutions:

  • Buy a pipe clamp that is the same size as the leaky pipes. (Clamps only work on copper and PVC pipes.)
  • Align the rubber gasket on the pipe with the leak point.
  • Install the clamp around the washer and tighten the bolt.

Note: The clamp is only for a temporary repair. You either need to replace the pipe or contact a plumber to return it for you.

2. Impaired Pressure Reducing Valve

Some homes had equipped with a pressure-reducing valve. This device regulates the pressure from the municipal water supply to your home. Relatively easy to find; look for the broadening device sitting on the water inlet.

Solutions:

  • You can adjust it by loosening the screw located at the top.
  • Turn it counterclockwise and turn on the faucet again to check for improvements.
  • If it is still too low, the valve may have a problem. In this situation, I recommend calling a plumber to check.

3. Damaged Water Lines

Another cause of low pressure in the faucet is damaged water pipes. A few years after of building of the house, the tubes of the house may leak. The line is under the wall and floor so that you won’t find a small thick leak. Another cause of low pressure in the faucet is damaged water pipes. Corrosion and debris can also affect water pipes in walls and under floors. When this reaches a significant level, it will affect the pressure of nearby faucets.

Solutions:

  • Air pressure: The plumber connects an air hose to the faucet affected by the local blockage. They blow air pressure into the faucet and then release water to observe the corrosion, calcite, etc., that fall off.
  • Replace the Damaged Pipe: This is a standard solution when the pipe blockage becomes severe, and the pipe had made of corroded old materials. The plumber will track the lines that cause the problem and remove them and install new pipes.
  • Pipe Cleaning: The plumber uses wooden clogs to locate the pipes and remove them from the rest of the line. Then they used a solid detergent to remove the old materials from the inside, the pipe placement and then restored.

Solutions:

  • Remove the handle.
  • Remove the Retaining Clip.
  • Replace the Cartridge.
  • And, check the water.

6. You Share Pipelines

Shared pipes are pipes that carry water to multiple houses, which means that your water supply had distributed to two or more households. For example, when someone uses the dishwasher when you wash your hair, you will often notice changes in water pressure. Only this time, it changed because there was someone next door.

Solutions:

  • Change your timetable and do when the water pressure is high.
  • Or, you can replace the pipe and contact plumbing.
