Homeowner cannot remove or install Moen 1222 shower cartridge due to apparent vacuum or pressure lock when local valves are closed, lacking the correct removal tool.

Existing solutions (plastic tool, brute force with board) failed to remove and install cartridge; Moen's recommended cartridge removal tool is not owned and unclear if it resolves vacuum/pressure issue with local valves closed.
