Well, I thought I'd share what I'm doing for other 274rk owners who may be running into the same thing.
After a lot of research I found no answers-- SOOoooo,
What I'm doing is replumbing the water heater by pass.
The total cost will be about $75. and probably about 2 hours.
If any one wants the plans and parts just pm me and I'll send a copy of the drawing and parts list.
