Replacing 40gal water heater (Rheem).
New expansion tank goes on supply side, and should be after the shutoff valve.
(A) Space is tight, is there a UPC Code requirement on maximum or minimum distance from the water inlet pipe? (3/4" pipe).
(B) Mounting expansion tank, should air valve face UP, or DOWN? I've read that facing up lengthens life of air bladder, but also manufacturers' want valve facing down. Couldn't find anything in Code about this.
(C) Supporting Tank: Metal or Plastic strapping ?
