I have a 5 year old P/W, Honda enigne 2700 psi @3 gpm. I maintain it real well. While working yesterday soaping water started running the other way through the detergent injection tube, over flowing the 5 gallon bucket. My question is would it be better to repair the pump, or replace the machine. I p/w about 4 days a month on average. I'm a one man show so da funds are low!!
