PEM has a new style of pressure relief valve. The old style has been replaced with a part that now has a hose barb that you can attach a hose eliminating water spray inside the washer cabinet. All future orders will be replaced with this new style part. You can view this item in the ‘General’ parts section for the P-300 and P-400. Please call or email us if you have any questions on how to install the pressure relief valve: 888-969-1601.
