I'm inspecting a house and found a water heater installation I've never seen before.
The pressure relief valve is on top of the water heater, and it has an IN and OUT.
The gas line is connected to the IN, and the OUT goes to the water heater manifold.:eek:
Can this be right? Normally I see a P&T valve with just a discharge to connect the overflow pipe to.
Anyone see this before? Is it code for residential?
Thanks
