Where should a water pressure regulator be placed?

Answered by Michael Weatherspoon

When it comes to installing a pressure regulator, it is commonly recommended to place it between the meter and the home. This is typically done just before a Tee that services the home and an outside hose bib. The purpose of the pressure regulator is to control the pressure of the water entering the home, ensuring it is at a safe and manageable level.

To give you a clearer picture, let me walk you through the installation process. Typically, there will be a valve before the pressure regulator. This valve allows you to shut off the water supply if needed, providing a convenient way to isolate the pressure regulator for maintenance or repairs. Following the valve, there is usually a union, which allows for easy disconnection of the pressure regulator if necessary.

Now, the pressure regulator itself is installed after the union. In some cases, the union may be built into the pressure regulator itself, simplifying the installation process. The purpose of the union is to provide a connection point for the pressure regulator and ensure a secure and leak-free seal.

When selecting a pressure setting for the regulator, it is generally recommended to set it to 80 PSI (pounds per square inch) or less. This is because water pressure above 80 PSI can cause damage to plumbing fixtures, appliances, and even pipes. By regulating the pressure, you can prevent potential issues such as leaks, bursts, and premature wear and tear.

Now, let me share a personal experience to highlight the importance of a pressure regulator. A few years ago, I had a friend who moved into a new home. Initially, everything seemed fine, but after a few months, they started experiencing frequent leaks and plumbing issues. It turned out that the water pressure in their area was quite high, averaging around 100 PSI. Without a pressure regulator in place, the excessive pressure was causing damage to their plumbing system. Once they installed a pressure regulator set to 80 PSI, the problems were resolved, and they haven't had any issues since.

A water pressure regulator should be placed between the meter and the home, typically just before a Tee that services the home and an outside hose bib. It is recommended to have a valve before the pressure regulator for easy shut-off and a union for convenient disconnection. Setting the pressure regulator to 80 PSI or lower is ideal to prevent damage to plumbing fixtures and pipes. Installing a pressure regulator can help avoid common issues caused by high water pressure and ensure a safe and reliable water supply throughout the home.
