Thanks for taking my question. I am experiencing sporadic water pressure increases. The prv is set at 60 psi but, and the time varies, the pressure in the lines will increase to 80 and even 100 psi. I just had the prv replaced one year ago and the pressure has been fine until a couple of weeks ago. I'm beginning to wonder if this may be the result of thermal expansion or is there a way I can test the prv? This problem makes me reluctant to leave the house for fear of busted fittings and/or faucets. Any advice will be appreciated.
