Came in for a standard check valve replacement. Ended up damaging the entire manifold to the machine. I allowed them to disassemble the little brother of the same year, maker, and type of machine. It came back broken. I was down for 3 weeks and the machine is half as strong as it was. I have to replace the entire power unit of the smaller machine myself. After 3 months the original machine they were hired to repair is now spraying oil and has completely lost power. Your money is better spent hiring a guy with a sledge hammer to hit the solenoids.Avoid at all cost.
