Okay. This is my second winter in this house and this problem just started about four weeks ago. My pressure relief valve is leaking water out of the extension pipe. I replaced the expansion tank and installed a new prv. I am still having the same problem. Sometimes the water drips, sometimes a trickle sometimes nothing. I did not have this problem last winter. Pressure in my Burnham furnace is 30 and temp is 180 but sometimes when it is firing,pressuret goes up to 40. That is when it leaks the hardest. I am wasting about a gallon of water an hour.
Could pressure be to high in system? If so, why did I not have this problem last year?
How do I reduce the pressure?
