Is your tap set NPT? Every one I have ever seen was 3/4 NPT. If your tap set is standard thread and not NPT that is your problem, and do not use that to tap the hole or you will likely ruin the water heater. Any plumbing supply house or home improvement center should have a 3/4 NPT tap on the shelf!
Exactly^^^^^^^^^
The pipe nipple worked........because it was NPT (National Pipe Thread)
which is TAPERED
Suburban has ONLY used 3/4" NPT
Hopefully OP didn't use that 1" SAE tap cause he will now have to buy a whole new water heater.
Suburban doesn't sell just tanks due to them being glass-lined
