TRAILER TRASH 2,
I THINK YOU ARE ON TO THE ANSWER. I BELIEVE THE WATER HEATER HAS A BACKFLOW VALVE BUILT INTO THE "OUT" LINE. I DONT THINK IT WORKS VERY WELL THOUGH. I THINK WHAT IS HAPPENEING IS THAT THE COLD WATER FORCES ITS WAY INTO THE WATER HEATER THROUGH THE OUT LINE. WHEN YOU TURN ON THE WATER AGAIN, IT MUST FIRST FORCE OUT THE COLD WATER THAT FILLED THE HOT LINE. THEN THE HOT STARTS COMING AGAIN. A BETTER BACK FLOW VALVE SHOULD DO THE TRICK.
JUST MY THOUGHTS ON THE MATTER, I HAVENT ATTEMPTED FIXING THIS YET.
MERV
