Getting drips from the water heater, water pressure coming into the house is 80PSI I checked it with a water
Pressure gauge. I have a potable water expansion tank on the water heater, it a WATTS, model number DET-5
Air charge is 20 - max air charge is 80 - max working(water 150)
I know the pressure coming into the house has to be the same as the tank pressure but is it safe to adjust
The tank to 80PSI?? Or do I need a pressure reducing valve put it??
Thanks for your help,
Joe

unless you have unusual spikes in the pressure, 80 psi does not require a prv.

Yes , add air to the tank. With that low of an air pressure I don't think is providing enough cushion for the expanding water.

If it is NOT a "closed system", it does not even need an expansion tank.
