Water System Pressure > 80psi
The City of West Richland is providing this notice as a courtesy to provide general information about water system pressure in the southern areas of West Richland which typically exceeds 80 psi. Please use the following link for a detailed map of the area with water pressure in excess of 80 psi.
Please note that while the City’s water system pressure may be greater than 80 pounds per square inch (psi), the water pressure within your home may be substantially lower, depending on the size of the plumbing pipe used during construction of your home.
The plumbing in residential homes is typically designed to handle 80 psi or less. With water pressures greater then 80 psi, there is the potential risk of a fixture or plumbing pipe leaking or rupturing (i.e. hose to washing machine, dish washer, etc).
Many homes within the identified area already have a pressure reducing valve installed within their homes, but some may not. The City is recommending that residents first check the water pressure at their home. If you need assistance with checking your homes water pressure, please call the building department at 967-5902.
Planned water system improvements will increase the existing water pressure in this area an additional 5 to 10 psi. If it is determined that your water pressure is 70 psi or more, the City is recommending that homeowners install a pressure reducing valve. This plumbing modification does require the homeowner to obtain a no-cost plumbing permit from the City’s building department.
The following link provides good information on how a residential pressure reducing valve protects a home from high pressure, how it works and how it can save a homeowner money by lowering monthly water consumption. In the brochure, the author talks about reducing water consumption can also reduce ones monthly sewer bill. This is not the case in West Richland as the sewer bill is not based on water consumption but is a flat monthly rate. Contrary to what is shown in the brochure, the City water meters are located in the ground near the back of the sidewalk, not inside or under the home.
If you have any questions or concerns about this notice or how to obtain a City plumbing permit to install a pressure reducing valve, please contact the City of West Richland’s Building Department at (509) 967-5902.
