How to Troubleshoot a Low Water Pressure Kitchen Faucet

One of the most common problems experienced by homeowners is low water pressure affecting the kitchen faucet. This can be caused by a variety of issues and different factors. So, in order to correct the issues, you need to identify the underlying problem and scope of the issue. Once you have isolated the source of your issue, fixing a low water pressure kitchen faucet may not even require professional help. Establish the Scope of the Issue: The first step in dealing with a low water pressure kitchen faucet is to determine the scope of the issue. If the low water pressure issues are affecting the whole house, it is likely to have a different underlying cause compared to a problem that is localized to just the kitchen faucet. In order to establish the scope of your issue, you will need to move around the house checking other faucets to test the water pressure. If the low water pressure appears to be affecting the entire house or a larger area of your home, you probably have a larger repair issue that will need the attention of a plumbing professional. If your problem appears to be isolated to just your kitchen faucet, you can proceed with your troubleshooting. Identify Your Problem Source: Low water pressure in faucets is often caused by pipe corrosion or clogs, but it can also be a pressure issue at the water source. The first step to identifying the underlying cause of your problem is to check if you have a blockage. This can be either in the pipe or the faucet head. Check the faucet by unscrewing the aerator screen in the spout of your faucet to look for any debris or sediment that could be compromising the water flow. In order to inspect your pipes, you will need to open up a piping access point. Unscrew your riser and back up the fitting so you can protect the pipe. Place a bucket to catch any water flow and turn on the water. You can then check the water pressure coming out of the pipe. Troubleshooting: If you have located a blockage, you will now need to correct the problem to restore water pressure. A blockage or accumulation of debris in the two 1/4″ inlets, supply hoses or screen in the aerator can be corrected by disassembling the faucet head and soaking it. A mix of warm water and vinegar is usually sufficient to clear any sediment and remove a blockage. Once cleaned, replace the parts and check the faucet to see if your water pressure is restored. If the flow is still slow, there is likely to be a problem with your pipes. At this stage, you may need to call in professional assistance. There is a possibility that sections of your plumbing may need to be repiped or cleared, and you may cause further damage if you attempt a repair. An experienced plumber has the tools, skills, and expertise to identify the source of your water pressure issue and provide a solution to restore normal water flow as quickly as possible.
