Just to keep you informed as to what we do here with a hot water TPR valve fitted water heater – we run the tpr valve discharge to waste but……. we also fit a relief valve on the cold water inlet to the water heater which is set at 70% of the pressure of the hot water relief so in fact when the water is being heated the cold water valve discharges cooler water to waste. But heck we ain’t got no water shortages or water meters in most places in this here God’s Own Country so it don’t matter much.
