Review on Optimized OEM Technologies Horizontal Axial Pump by Ryan Marx

I took the opportunity and bought this for a DEVIL BISS washing machine with a 5hp Honda motor. Installation was very easy, however, when starting up, pressure was similar to that of a garden hose. I contacted support and spoke to Donna who advised me to adjust the pressure. Opposite the drain hose is a sprint and nuts that can be loosened and then the large nut turned clockwise to increase the pressure. I did and the pressure is now as it should be. Directions are terrible. If the instructions were more complete I wouldn't need to call support.
