Thanks for the quick reply. Doesn't look like there is a check valve. I do have a gate valve in the line from the pump back into the line that feeds the cold water into the tank, and there is a gate valve between that line junction and the cold water inlet nipple of the tank.
I did go look at the old tank and there isn't a rubber heat trap (and the metal nipples didn't have a ball bearing type heat trap either) . The replaced tank was over 15 years old so that may explain why.
I re attached everything the way it was originally except for installing braided stainless steel hot and cold hoses for an easier replacement down the road for myself or the next home owner.
When hot water is turned on at a faucet or shower head, the pump and its up and down stream supply lines become cold to the touch. I just felt the cold water supply line and it's hot as well. I'm guessing that's normal as hot water is being mixed with the cold back into the tank. That was why I asked about the heat trap. Seems almost like it shouldn't be there in a recirc. Pump set up.
Sorry if I'm rambling. I'm trying to give an accurate and complete list of all the symptoms. Must be the architect in me.
Wondering ? Can you download pictures into this forum? That might clear a lot of the confusion.
