Low water pressure can be more than just a small inconvenience. Your daily routines can become arduous chores, and your appliances may even lose their efficiency. It is important to know how to troubleshoot low water pressure to help restore normal water flow and ensure that your home runs smoothly. The following guide will take you through the steps needed to identify and solve the problem effectively.
First, obtain readings of the water pressure throughout the outlets in your house. Collecting water from each outlet for one minute, the amount of water that comes out in a minute, can be done by measuring their volume. This will provide you with the flow rate per minute of each outlet. A flow rate that is highly below what is generally accepted as normal may suggest whether the issue is limited to a particular area or is generalized within the house.
If only one outlet has a low-pressure problem, it could be a more localized problem. In some cases, if the issue is only with your hot water supply, then this would be related to your water heater. On the other hand, if multiple outlets within the home have low pressure, you may have an overall problem at large with your water system.
Check whether the low water pressure exists at one or more individual fixtures, faucets, and appliances or if it is a widespread problem that has occurred throughout the home. If the symptom only occurs at one outlet, the following issues could be the reason for it:
In such cases where the water pressure in the entire house is low, the problem is usually with the general water supply system or plumbing infrastructure.
Two important valves in your house control the supply of water: one valve by the water meter, which is on the street side of your home, and the main shut-off valve, which is located on your property. Sometimes, these may be partially closed, therefore limiting the flow and pressure of water.
Make sure they are fully opened. A partially closed valve can reduce the volume of water coming into your house, leading to low pressure. These valves may be partially closed accidentally, but opening them might fix it.
Most homes have a PRV (faulty Pressure Regulating Valve) located at the very point of entry for the main water line into your home. This valve resembles a bell, and it controls the water pressure entering your home. If the PRV is faulty or set too low, then you may have low water pressure.
To change the adjustment of the PRV, locate the adjustment screw usually found on the top of the valve. This typically raises water pressure and is done by merely turning the screw in a clockwise direction. Make small adjustments and then test the water pressure after each change until you reach your desired level.
Leaking pipes can be one of the major causes of low pressure. Check your home for signs of leaks, including basement areas, under sinks, and around fixtures. Visible leaks or water damage often provide evidence that water is escaping from your plumbing system, thereby reducing the pressure.
Such rusty or colored water would mean that the pipes are old or highly corroded. In that case, seeking the services of a professional plumber would be a great idea. This may be due to the need for new or replaced pipes in cases of worn-out or damaged ones. This helps to restore the correct water pressure and avoid other mishaps.
However, while this list can help troubleshoot many of the low-water pressure issues, some of these issues may require professional help. For any condition that you fail to solve on your own or suspect more serious problems with the plumbing system are involved, don’t hesitate; instead, call a licensed plumber immediately. They may be able to provide professional diagnoses and make recommendations based on such diagnoses.
