Maybe my head has gone soft Brian.


Are you trying to tell me that the H2O temp would go up as it leaves the TPR and goes from 150 P.S.I. to 0 P.S.I.?




Hint: Compressibility of water

Believe it or don't: One end of garden hose attached to sump pump discharge; Other end of garden hose clamped to TPR drain line. Turns out the elderly gentleman had gone slightly senile before admittance to the nursing home.

Just the opposite Michael, I was agreeing with your assessment that steam would be hard to produce in a standard, functional water heater.

Agreed, and consider this... you will only get steam where there is an absence of water in the system ie... air pocket. Water and steam cannot occupy the same space. And yes, steam can condense to return back to the liquid state, but not likely in the short distance of the TPR draintube.
