1. The BEST way to determine water flow and pressure is to NOT have the Water Heater heat up the water. Then OPEN the outside Pop off Valve. See if you have pressure/volume as it should be. IF NOT, then the check valve on the cold water intake(if you have one) is clogged/bad. Replace it.

4. Put the system back exactly as original with new check valves and the new valve you purchased and problem will be fixed. Doug
