New (Larger) Expansion Tank Causing Reduced COLD Water Pressure?

[Busthead]

Hello,


Replacing a 2.1 gallon thermal expansion tank with a 5 gallon unit appears to have caused the cold water pressure to decrease. The toilet tanks fill more slowly. The water from the fridge dispenses more slowly.


I confirmed the pressure at a hose bib and increased the expansion tank precharge to 60 PSI.


I'm a DIYer, not a pro but I'm also not crazy. Something has changed. I just don't know how or why.


Please help!

The laws of physics say the tank is not to blame. Most likely the valve you shut off to change the tank is to blame. Another possibility is sediment was disturbed and is clogging the end fixtures.
