You’re trying to enjoy a nice, hot shower, yet the water just trickles out. When your water pressure just isn’t what it should be, it leaves an impact. Not only that, low water pressure can be indicative of more serious plumbing problems. There are many potential root causes of low water pressure, and with some troubleshooting, you may be able to figure it out yourself. If you can’t or if you simply don’t have the time to launch a full-scale plumbing investigation, you can rely on Hubbard Plumbing for plumbing services in Suffolk County. In the meantime, here is how you can troubleshoot low water pressure.

Step One: Identify Where the Low Water Pressure Is

Are you experiencing low water pressure only in the shower, or is it present through all faucets in your home? Go through and check all the carious fixtures that supply your house with water, from the showerhead to the kitchen sink to the outdoor faucet. This will help you determine whether or not there are specific problem areas, or if it is an overall issue of water pressure. Also make sure to run both hot and cold water, because if the water pressure is only an issue for hot water, it indicates an issue with the hot water heater.

Step Two: Address Problem Areas

If the low water pressure is only an issue in one or two areas in your home, it’s likely due to a clogged faucet or aerator. To address this issue, remove the end of your faucet and examine the aerator for buildup. You can clean the aerator by soaking it in vinegar and water. Alternatively, you can replace it. Before you replace the aerator, run the water. If the water pressure is still low, it indicates a more general problem with the overall plumbing.

Step Three: Address Overall Issues

Alternatively, it could be an overall problem with your plumbing. Here are some simple, general problems that may be causing low water pressure.

PRV or Water Shut Off Valves

First, look at the Pressure Reducing Valve (PRV). This bell-shaped valve is usually on the line where it enters the home. You can see if it is the source of the issue by adjusting the screw on the valve. Turning it clockwise should tighten it, increasing the water pressure. You can do the opposite by turning it counter-clockwise. If the valve is broken, it may need to be replaced.

Then, check the water shut-off valve at the water meter. Even if it has only been adjusted slightly, this can have an impact on water pressure. Turn the valve so it is completely open. Finally, test your faucets. If your water pressure has been restored to normal, this indicates that one of these valves was the issue.


Then, check your home for leaks. Toilets are one of the most common sources of leaks in the home, so start by checking the tank of each toilet. Drop some food coloring into the tank, then wait an hour. If the color is in the bowl, it indicates a leak.
