Home water pressure problems may present themselves in different ways, all of which can be quite frustrating. Faucets may take forever to fill a sink or bathtub, or a showerhead may not give you that strong spray you want. Your dishwasher or washing machine may take much longer to run a cycle than it should.
When only one fixture has low water pressure it’s likely that the problem can be remedied if you just focus on fixing that one fixture or the pipes serving it. But widespread water pressure issues affecting the whole house indicate different problems. If your home water pressure seems low then the first thing to do is to narrow down the cause.
In many homes, there are two major shutoff valves controlling water to the home. The first is the water meter valve, located right next to the water meter on the main city supply pipe serving your home. Normally, you will not use this valve, as technically it belongs to the water company and is typically used only by water company personnel. But if your water pressure is low throughout your house, especially after some work has been done on your plumbing system, it’s possible that this valve is not fully open.
If you have recently had a repair done and are now noticing a reduction in the water pressure throughout your house, check the meter valve. It may be located on an outside wall of the house (in warm climates), in an underground box between the house and the street, or in an interior utility area, such as a basement or attached garage.
The valve is fully open when the valve handle (which may be just a metal tab that is turned with a special wrench) is parallel with the water pipe. If the handle is set at an angle to the pipe, it is not fully open.
Is the Main House Shutoff Valve Open?
As with the water meter valve, this main shutoff valve is sometimes left partially closed after some kind of repair has been done to the system. If your water pressure has mysteriously lessened after a recent repair, there is a good chance that the valve wasn’t fully opened after the repair was completed.
When the pressure regulator fails, you will notice the effect on all of the fixtures in the home, and it will happen rather suddenly. Although a pressure regulator can sometimes be replaced by yourself with the same brand and size, in most cases is it better to call a Green Apple plumbing professional to take care of it. Replacing it requires shutting off the water to the home at the water meter shutoff valve.
To get an accurate reading of your water pressure, you can test the pressure by attaching a water pressure gauge to the outdoor hose spigot closest to the water main or pressure regulator. Recommended water pressure is 52 to 75 pounds per square inch. If your pressure tests very low, this may indicate a failed pressure regulator.
Do You Have Old Steel Water Pipes?
This problem develops over the decades, so the reduction in water flow is very gradual; you will not notice a sudden drop in pressure. However, if you move into an old house with steel pipes, the pipes may have significant corrosion to start with and the problem may worsen relatively quickly.
Unfortunately, the only solution for corroded pipes is to re-pipe the system with new copper or plastic water supply piping. It is the only way to solve the problem. Usually the best option for re-piping these days, in terms of cost and ease of installation, is to use Pex tubing rather than copper pipe.
