Saw this relief valve servicing the gas line between the HWT and furnace. Can’t say I’ve seen this before. Am I right in assuming its a relief valve? Comments please.
That is a watts 210 I believe. It cuts off the gas to the water heater.
That looks like a valve not a relief device.
The below and to the left is the same except for the missing handle.
installed watts 210
Yeah. It’s not even going into the WH is it? I can’t tell.
