Question about Water Heaters
I have a 9 year old Rheem PVW50. Last year I replaced the drain valve, T&P valve and the anode rod. The old anode rod was worn out. A couple of months ago I noticed the T&P valve was leaking every once in a while. Then it started every day. I read an article that said if the T&P is leaking to open the cold water faucet, if the T&P stops dripping it is not the water heater. But to check it out get a watts gauge with high pressure marker. So I purchased one and found out the cold water was going up to 110 psi and hot water heater up to 150 psi. Found out I need to replace the Watts Pressure Reducting Valve AU25B. After replacing valve cold side is now 50 to 60 psi. However, the hot water heater registers 50 to 60 and when the water is being heated may go up to 100 psi. No water is leaking out of the T&P valve or anywhere else. Putting my ear to the heater I can hear a little grumbling out of the tank but not overly so. So my question is 2 fold. First, is the water pressure of 50 to 100 in the tank ok? Secondly, when is the best time to replace the tank but still get maximum usage out of the water heater? Thanks for your help.

I'm assuming your talking the pressure relief valve is what's leaking. If plumber says water heater is o.k., then we'll go with that but need to find reason for excess pressure. 2 reasons usually causing that 1) water temperature is getting too hot, or 2) incoming water pressure to tank, is too high.
Have you noticed any difference in those 2 areas such as: water flow at all taps seems to be stronger, even cold taps? Have you payed close attention to hot water temperature, does it seem hotter than usual? If it does, or did seem hotter, have you tried adjusting thermostat on tank down a few degrees to see if that stops the tripping of the pressure relief valve?

These are interior metals, similar like rock used in a sauna, to help keep water hot longer. Here is somethings to check out.
