Plumbing-City Water Pressure

plumbing-faucetCommon water pressure should be somewhere between 45 and 125 psi.

There are many contributing factors that impact this value that may include 1) distances to the water source, 2) size of the distribution lines, 3) elevation of the water supply, 4) primary water line size and the list goes on. However, your plumbing system should work correctly if the pressure is within the 45/125 psi range. If you have just moved from the city to a rural area, do not be surprised if the water pressure is lower than what you have been used to. Contact your water provider to determine if they are within their specification at your house.  (If your house is served by your own well, the primary pump will determine the pressure. Wells will be covered as a separate post.) There is no maintenance inspection associated with the water pressure item other than knowing what it is as a reference as it can cause the system to act differently than normal. Recognizing the  changes will help to determine if any action is required during high pressure conditions, you may experience excessively noisy pipes, clanging or hammering. Low pressure is pretty obvious… low pressure and low flow. Typically, these conditions can be associated with the service provider performing work that required them to open up or turn off the water near by. If the condition does not pass in 24 hours, you may call them to determine how long the condition could continue.  TIP: If you experience low pressure, take the opportunity to fill up some gallon jugs as you may totally loose water pressure before the water line repair is fixed.

To check your water pressure, simply screw the pressure gauge on to an outside faucet (TIP: closest to the water meter) and open the faucet. This will provide an accurate reading. If you find it to be low or high and intend to call the water department, provide them the reading to assist them in their resolution. (TIPKnowing what the water pressure is, under normal conditions, is also valuable information

Since water lines stay under pressure and are considered a closed system, turning the water off, opening the pipes(s) and exposing the interior of the water line allows dirt and mud into the system. It doesn’t matter whether the work  is performed by the water provider, plumber or yourself, it can cause clogged water filters, strainers and faucet nozzles. If you are aware of the work, wait about three days, then clean your faucet strainers/nozzles/filters. Look for a future post on this subject. Plumbing-Faucets.
