How water is regulated in your home
You might have noticed that the water pressure in your home stays fairly consistent day-to-day. That’s a result of a little device called a pressure-reducing regulator that keeps water pressure around 45 pounds per square inch (PSI) in most modern plumbing systems.

Older homes did not have these devices installed with original construction and may experience more water pressure fluctuation.

The regulator is installed on the home service line that’s connected to our water distribution line. It can be found on the exposed piping where the water service enters the home or also located in the garage.

Roseville maintains water pressure of at least 50 PSI throughout the distribution system, though it can be as high as 95 PSI depending on where you live. The pressure-reducing regulator keeps high pressure from inconveniencing you or damaging appliances such as dishwashers, icemakers and washing machines.

Unfortunately, your pressure-reducing regulator is a mechanical device that can fail, noticeably reducing the water pressure in your home. The regulator is part of your home plumbing system—not a component of the city’s distribution system that delivers water to your home. Just as with other parts of your home’s plumbing, the regulator is your responsibility to maintain and repair. If it fails, contact a plumber to replace it.
