No water pressure.
I just changes the release valve on my water heater due to a broken one. I got everything finished up ( water turned on and lit, works fine). Now I have no water hot or cold to my bathroom or kitchen sink. My bath and downstairs sink work fine. The two not working are on opposite ends of the water pipe with the two working from the middle of the pipe. Also I only shut off cold water to the heater, so we had cold water for the night in all sinks.
Any help much appreciated. Asap plz and thank you.
