I have this 573 backflow preventer but it is leaking at the unions (checked with dry hands and always wet). The guy who fitted it just keeps applying more tightening torque but to no avail. I get sudden puddles (will now check to see if it is from the valve) and a constant drip from the unions. I cant have this leaking non stop as I am wanting to finish my basement. Are there any suggestions?
