During certain times of the day, the water pressure in the house is enormous. The toilet tank does not fill up with water, yet when I bleed the water from a sink and release the tension of water, the toilet tank then fills up. Once the water line is relieved, the pressure returns to normal. I'm not sure if I need to change the regulator again, as I just put a new one in 6 months ago. During high pressure times of the day, the relief valve on my water heater also drips water. However, once I open and release the tension of water, the water heater stops the drip. This problem is killing me.

Well, or city water?

What time of day will this happen? Purchase a hose bib pressure gage ,(see image) and tell me how high the pressure builds to. Regards, Tom

City water, and the pressure builds up around 1 pm. Will test pressure tomorrow and let u know. Thanks

Pressure is coming in from the city and 175 psi, and the regulator is dropping it down to 50 psi. However, I just put in a brand new heavy duty regulator, and my release valve on the water heater still drips water during and only during the 1pm time of the day, when the pressure is extremenly high. I can tell the pressure is abnormally high because when I bleed the water from the bath sink, I can feel the abnormal force of the water coming out for about 3 seconds, and then it stabilizes.

What is the significance of 1:00 PM? Is there anything that uses water every day in your house at 1:00 PM? I can not think of anything that runs periodically during the winter except a water softener, but that is usually at night, and hopefully not every day. Plus, that would only help to stabilize the pressure, not raise it. At 1:00 PM, how high does the pressure get past the regulator?
