How high the max pressure of water heater can be?
Edward S asked:
Water heater has a pressure relief lever. But how high the pressure will be, then the relief leaver supposes to begin work in normal case? Does the pressure will go up 15 PSI?
Thanks.
Since the thread nipple at water heater is rusted into leaking and very difficult to take out, I think to use the connecting method of auto radiator and use rubber hose to connect the nipple and the cold water supply. But I think the rubber hose may strong enough to hold 60 PSI. Any idea?

your average water pressure will be 60 psi

your pressure reief valve will open at 150 lbs , or 210 degrees ……… normal operating pressure depends on your local water authority – all in all i agree 60 lbs is normal -

I have found that if the water pressure is above 90lbs in the house, and you don’t have an expansion tank that in heating the pressure will rise to where it will cause the relief to open.
MY utility says 40-80lbs is normal 60 ideal but they also say their only requirement is to provide “adequate” pressure and if it is too high then you need to add a regulator.
15 psi? Are you talking about a boiler for hot water heat and not a water heater for your potable water? That is more like the pressure a boiler runs at.
