I didn’t think about doing a bypass type valve. When I look online most seem to be made of nylon impregnated plastic or thin soldered metal. I have trust issues with those. I will just put in two globe valves ($90 each at Grainger) so I can leave them partially open. If the water heater fails, I’ll just leave the valves in the off position and put in a standard 120v residential type heater if the Rariton ends up costing an arm or a leg. I need both my arms and legs unscathed.
