injecting anti freeze
I use auto anti freeze like most of you do, but I pump it through the machine (including the heater and hoses) with a modified pump up sprayer. I cut the hose, removing the control valve, lance, etc. and added a male water hose connector. I mix the antifreeze, load the pump and pump to through the water inlet until it comes out the hose. I blow out the pump first, using the Shreader (sp?) valve on the pump. I have another male hose end attached to a male air compressor hose fitting. I use this to blow out water hoses and could use it on a p/w without a valve.
