Have used this Midwest testers for years and never have had any issues. Always fast shipping from Backflow Supply.
Very good buy and arrived perfect on time!
Shopped around and backflow supply had the lowest price for a Midwest 845 3 valve. They even threw in a pocket knife and notepad !
Haven’t used the gauge yet but the company I bought it from was a great experience. Will use them in the future . Backflow Supply.
excellent had what I wanted
