7 Reasons Your Water Pressure Is So Low

water pressure low in house suddenly

If you determine the lack of water is widespread throughout your home, check in with your neighbors and the water company. Contact your nearest neighbors and ask if they have the same problem. Since your regulator will maintain pressure at the level you set, try setting it bit higher to feel higher pressure. Just remember not to exceed about 60 psi to keep your pipes in good working order. This can happen more with hard water, which has higher mineral content, and installing a water softener can solve the problem. If a valve is leaking or broken, it’s important to fix it as soon as possible.

Step 3: Start with Your Valves

Check for closed water valves, open valves that should be closed (such as hose spigots), and other issues that might affect pressure. If a specific sink, shower, or appliance is involved, the problem probably has to do with the control valve or supply line that feeds the fixture. In the case of a weak shower, wait until the dishwasher is finished running and try turning on the shower head again.

C​logged Pipes

Remove the valve and inspect it for any damage or wear and tear. To check your home water pressure, you would need to purchase a pressure gauge from a hardware store, attach it to an outdoor faucet, and record the reading. But before that, it’s best to confirm whether your issue is indeed related to plumbing issues in your home or something else. If there were any utility repairs or work done on your home recently, and your entire home experienced a sudden drop in water pressure, it is possible that’s the cause. Buildup from hard minerals, such as calcium and magnesium in your water, are common hard water problems that affect fixtures and faucets. The tiny holes in your shower head, for example, can easily get clogged with the residue that dissolved minerals leave behind.

Inspect the Shower Arm

Depending on the type of valve, you may see a ball valve with a lever that moves 90 degrees or a gate valve with a handle that rotates to open and close the valve. To open a ball valve, simply move the handle so that it lays in line with the water pipe. In order to fully open a gate valve, turn it counterclockwise until it can no longer turn, then turn it back a quarter turn to avoid potential leaks or a seized valve.

This can cause a buildup of mineral deposits that gradually constrict water flow. Low water pressure can be caused by a variety of factors, such as clogged pipes, leaks, or problems with the municipal water supply. There is a device installed on most main water lines called a pressure regulator.

Recap: What To Do When Your Water Stops Running

Look for water-related incidents online and see if they affect you. Any kind of water line repair, pipe replacement, or maintenance could make the water supply weak in your area. If your problem is because of this, there is little to nothing you can do until they finish. It can happen to any part of your house from your kitchen tap to your flushing toilet. While you can learn about these things before moving in, there are ways you can lose strength over time.

While you can see what your pipes are made out of, this is where your investigation should end. Unlike other problems that can cause decreased water pressure, you cannot check this one yourself. If you suspect your pipes may be clogged, call a licensed plumber to take a look and determine whether the pipes need to be cleaned or replaced. If you need to cut off your main water supply for repairs around the house, this is where it happens. A plumber will first need to identify the cause of the low water pressure before they can fix it.

Q: Can hard water cause low water pressure?

You should know though, if your aerator is corroded and clogged, there's a good chance it's also happening inside that fixture. Luckily most fixtures aren’t that expensive and are fairly easy to replace. This is good news because if cleaning the aerator doesn’t fix it, replacing the fixture is your next best move. Finding out which of these applies to you and what’s causing it is the first step in fixing the problem. Are there white spots on glasses and silverware coming out of the dishwasher? If you answered “yes” to any of these questions, you might have hard water.

Similarly, corrosion causes oxidation to build up inside pipes, which can block water flow. This issue is often seen in older galvanized steel pipes, along with mineral scaling. Over time, corroded pipes can develop holes and eventually fail altogether. Water pressure that’s too high can create plumbing issues and cause unnecessary stress on appliances like dishwashers and clothes washers. A regulator protects pipes and appliances, and it can extend the life of plumbing fixtures. This is a valve that belongs to your water company, and that is usually located underground.

If the pipe's exterior looks like a penny, it is most likely made of copper, a very common piping material. These are usually black and are easy to identify by the visible clamps. The surface of galvanized steel pipes will look steel-gray in color. If the low water pressure seems to only be affecting one or two fixtures, then there is likely an isolated cause for this situation.

Our skilled plumbers are always ready to handle all your plumbing needs. Since there are different water pumps, it would be pointless to explain how to reset the pump. Keep reading for more detailed explanations of these issues and how to fix them. Remember that, in most cases, you will make your life much easier and avoid further complications by calling in a professional to address the problem.

In some cases, the issue actually has nothing to do with your home’s plumbing. There are all sorts of ways that the water delivery process can go wrong before it reaches your home. For example, if construction breaks a large supply pipe that goes toward your home, your water pressure can drop. You might also have lower water pressure if an issue at a water treatment plant briefly reduces the amount of water that your city can supply.
