9/23/13: Water Pressure.
50 psi (pounds per square inch) to 70 psi, is standard in most homes. Sometimes when we visit friends or vacation in another area, we remember the fantastic shower with excellent that water pressure. When we get home, our low water pressure makes us want more.
There are several factors that determine the “natural” water pressure in your home. First, the size of the water main that comes into your house can make a difference. Generally a two-inch pipe is pretty standard. If you have a one-inch pipe coming in, that could be an issue. Check this out first. Second, the dynamic pressure of your water system increases when your pipe sizes reduce going to the fixtures, within limits. For example, your shower head increases the power of the flow but the line pressure stays the same. Third, there are systems that can be added that channel water into tanks where the pressure can be manipulated, and then these tanks feed the house with high pressure water. Here are some tips on keeping your water pressure as high as possible:
1. Check the water meter. If the water meter is not completely on, it can cause pressure problems.
2. Check the main shut off valve. Make sure this valve is wide open, all the way on.
3. Check the pressure regulator. When this device fails it can cause either a big increase in water pressure or a big decrease. If this device has failed, or is in disrepair call MH Mechanical.
4. Old or corroded pipes. These can be a cause of lower water pressure. It’s especially true of old galvanized pipes. You can get a buildup inside the pipes that slowly lowers your water pressure over the years. While re-piping can be a major plumbing expense, it can make a big difference.
5. A clogged screen on the water line. Some water meters have a screen where the town pipes connect to the inlet side. The screen keeps out small particles that can harm the meter. Cleaning or replacing the screen can solve the pressure problem.
