My gas tank water heater is 14 years old and I'm getting ready to replace it. The current water line installation is straightforward. We're connected to a city water supply source and we have an open water system. No expansion tank. Also we're only using our heater for domestic hot water, not house heating. One pipe in and one pipe out.
I took a close look today at the inlet and outlet pipes on my new Rheem heater (the heater is not yet installed), and I see that they have pre-installed ball type heat trap nipples - new to me. Researching these on line it sounds like the cold water trap nipple does not completely block tank expansion flow back into the cold supply. Good to hear but is this accurate? This old 50's house does not have a basement floor drain and I'd hate to have the relief valve pop - big mess.
Also, I've read that the ball type heat trap nipples were/are noisy, but the posts I read were from around 2004/2005. The posts stated that a flapper type nipple is available. This heater was manufactured in Sept 09 so you'd think the noise problem would be solved by now. Should I be OK with these?
Thanks
