Adjustable Water Pressure Regulator with Gauge - Brass Water Flow Control Valve for Home Plumbing, Irrigation System & RV Use

You just bought a new plumbed in espresso machine and are reading the installation instructions.  You notice that the installation instructions say that the maximum pressure is 2-3 bars (30-45 PSI) but the typically city water pressure in Canada is 4-5.5 bars (60-80 PSI).

The adjustable water pressure regulator can be set between 0-8 bars and will also protect your espresso machine against water pressure fluctuations.  It even comes with a built-in gauge!

Connection is John Guest 3/8" (ø external 10 mm)
