Water Pressure Alerts

 

If you get pressure alerts or notifications when you run water, there may be an issue with your municipal water supply, or with your pressure-regulating valve (PRV). For example, if your pressure is too high (whether water is flowing or not), it is possible that your PRV is no longer functioning properly and needs to be replaced.  Depending on the age of your home, it is also possible that there is not a PRV installed; check with your plumber.  Just like blood pressure for people, high water pressure is a serious risk to the health of your home plumbing system.  Many appliances are only rated to handle incoming water pressure up to 80 psi.  Constant pressure above that level can cause supply lines to appliances to fail prematurely and burst.

Water pressure too low could indicate that there is an issue with the water line coming in to your home.  This could indicate that there is a break in the water line that supplies your home before it enters your home (like a broken line in your lawn due to settling or aging). This can also be caused when there is work on or damage to the water main near your home (like during construction).

See below for the types of pressure alerts you may receive and what they mean:

 

  • "Water pressure TOO LOW at 'location' at [time]." This means the Control measured the temperature of the water in the pipe to be less than 30psi.
  • "Water pressure TOO HIGH at 'location' at [time]." The Control has measured the temperature of the water in the pipe to be greater than 90psi. Your Control may be installed on the wrong side of the PRV - check the diagram below for the correct order.
