Hooking up Suburban water heater - User Error
I bought a suburban water heater to replace the one that someone had screwed a boat plug into the anode prior to me purchasing (thanks for helping me out w/ that one, wouldn't have figured out).
Now I have a different issue, water fills for a few minutes then sprays out the back of the tank. The PEX tubes are not cracked.
There was two adapters I took from the old tank. I was 99.7% sure I did not mix them up (not that it means anything, the old tank was shot anyway).
I put the adapters in the new tanks with the one with the valve (see photo) in the hot water (top of tank) so that water could come out, but not backflow.
I've attached the setup, there is a bypass valve at the bottom T intersection above the blue towel (see photo) but not at the top T.
Any help would be appreciated, assume I'm a moron because clearly I missed something because it doesn't work. I've probably missed the obvious somewhere.
