PRIMUS Plumb-In Kit: Pressure Reducing Valve (PRV)

Unlock the full potential of your WPM PRIMUS espresso machine with our official Plumb-In Kit. This Pressure Reducing Valve (PRV) allows you to transition from manual tank fills to a seamless, direct-water connection, providing a continuous water supply for high-volume brewing and ultimate convenience.

⚠️ Critical Installation Requirement

To protect the precision components of the PRIMUS, this valve must be installed downstream of a high-quality water filtration system. * DO NOT connect this valve directly to the mains water supply.

• Why? Unfiltered tap water contains minerals and sediment that cause scale build-up and internal blockages, which can compromise pressure stability and significantly shorten the lifespan of your espresso machine.
