Heat traps nipples same direction? In wrong direction?
I just put in a new hot water heater. I noticed plastic and flaps inside the nipples, the nipples came with Teflon on so I put Teflon side down and installed the hot water heater. I'm not a plumber and I thought the nipples were funny so I started googling and noticed that the hot side and the cold side are probably different. There was nothing to tell me which one was hot or cold so I have a 50% chance that I put them on the wrong side :(
Is this dangerous? Does it make that much of a difference that I should be concerned and take it apart and check ( it took me 1/2 a day to connect it so its no short job to check and if I was wrong swap them).
Much thanks!!
