I purchased from steambright a pumptech 500psi regulator repair kit for one of my portablesM500, it came with a piston black rubber that goes on the piston and another metal ring with a rubber in the middle. I am trying to figure out does the round ring with rubber go in first and than piston? I am not sure! Or just piston? Not sure if this peace is something extra they send for other similar machines. Can you help?
The flow switch that fires the burner would have to be able to be work under the lower flow of CC tools.
There are lower flow switches available, but I am unfamiliar with your unit to know if it can be changed to a lower-flow fired switch if necessary.....they are usually pretty standard switches that are changeable.
