You're right. It (combo ball/pressure relief valve) might be an 80# or 125# release, but who knows? He has to verify a PRV install or not, w or w/o a check valve feature. He then has to establish delivered house pressure with the WH turned off and go from there.
Or he could simply move the valve drain indoors and get away from the freezing.
