Winterizing Girard Tankless WH
I'm sure this is explained elsewhere, but I couldn't find it.
I want to use the air compression method to blow excess water out of my Girard Tankless Water Heater, but I don't have a clue where to hook up my compressor. If someone can explain in detail, for instance, is there a valve I need to open? One I need to shut? And where do I insert the compressor hose?
Thanks for any info - I'm trying to do this right now, in the rain and the dark. Have mercy.
PS: If there's a video.....?
