Just had a plumber install a new shower mixing valve and spout. He recommended caulking around both the spout and the valve. The spout advice seemed pretty obvious. But the valve has the foam seal on the backside of the cover plate. What to the pros do? Is this foam seal adequate? Could plumber's putty behind the mixing valve cover plate replace caulk on the outside?
